How to keep your passenger car engines running smoothly
Today’s hardworking automotive engines need maximum protection against high-mileage wear, corrosion, and oxidation. From engine and gear oils to greases and transmission fluids, choosing the right lubricant to match every job is critical to achieving peak performance from your passenger car engines.
Our guide offers practical ways to protect and maintain all types of passenger car engines. Learn how to select oils and lubricants that will keep your automotive engines motoring on for thousands and thousands of miles.
THREE TYPES OF ENGINE OILS AND WHEN TO USE THEM
Protect your vehicles’ engines with the right oil
All engine oils have many “jobs”. To simplify: An engine oil’s primary job is to provide sufficient lubrication to protect against the heat and friction caused by the moving parts inside internal combustion engines. However, not all engine oils are the same, and it’s vital to know which one is best suited for each job.
Engines that are properly maintained with the correct oil type will run smoother and last longer. But choosing the right oil can be complicated. Engine type and age, climate, and driving conditions all impact the wear and tear of automotive engines. Understanding the different engine oil types, specifications, and additives will help you select the best oil that matches the needs of each vehicle you service.
1. Full Synthetic Engine Oil
Advantages of Full Synthetic Oil
Full synthetic engine oils are made from a petroleum base oil that is purer than a conventional crude product. Fewer impurities mean that the oil doesn’t break down as quickly and protects your engine longer than conventional engine oils or even synthetic blends. Using full synthetic motor oil results in better fuel efficiency, more horsepower, and improved wear protection.
An engine’s parts are constantly moving at high speeds, creating heat and friction. Full synthetic motor oils are engineered to retain viscosity, to resist extreme heat and to still flow quickly in winter temperatures, allowing your engines to run smoothly year-round.
Turbocharged engines are designed to improve performance and fuel efficiency. However, that improvement comes at a cost: higher temperatures. Because these engines run hotter and often have very tight oil passageways, they require a low-viscosity engine oil that can flow quicker and still withstand the heat and friction generated by a turbocharger shaft spinning at 200,000 rpms. Full synthetic engine oils are the best-suited to perform at high temperatures, protect against thermal breakdown, and retain viscosity under these extreme conditions.
As oil flows through a vehicle’s engine during combustion, deposits form. Deposits from conventional oils can turn into sludge that builds up in the engine, reducing efficiency and lifespan. Synthetic engine oils contain chemical detergents and other additives that resist the buildup of deposits. Cleaner engines run smoother, more efficiently, and longer than dirty, congested engines.

Full Synthetic Engine Oil - Euro
European cars require different oils with different specifications than cars manufactured in the U.S. This is due to the European Union’s stricter emissions standards, the more frequent use of diesel engines, and longer service intervals.
European emissions standards
The EU more strictly limits carbon dioxide (C02) and carbon monoxide (CO) emissions than the U.S. Because of this, European OEMs use more diesel engines. Diesel engines emit less CO2 and CO and provide better fuel economy but emit more nitrogen oxides and particulate matter. To counteract this, diesel-powered European cars are equipped with filters and catalysts to reduce tailpipe emissions.
Oil components, such as sulfated ash, phosphorus and sulfur (known as SAPS), can shorten the lifespan of diesel engines and emissions devices. Therefore, it is imperative to choose synthetic oils formulated specifically for European vehicles that contain lower SAPS levels to protect emissions-control systems.
Longer drain intervals
While in the US and Canada, the traditional 3,000-5,000 mile oil change still exists, European automakers recommend longer oil change intervals – from 10,000 to 15,000 miles. Longer drain intervals require a robust synthetic oil capable of protecting against wear, deposits and sludge for the duration.
Each European OEM’s recommendations and specifications vary slightly from one another. Overall, European OEM engine oil specifications tend to be stricter on different performance characteristics than in the US and Canada. These specifications require technology delivered exclusively by full synthetic oils.

2. Synthetic Blend Oil
Just as the name implies, this type of oil is a mixture of synthetic base stocks and conventional crude-based oil. Synthetic blends provide some of the performance advantages of a full synthetic at prices more closely comparable to conventional oils.
Using full synthetic oil costs about 30% more than using a synthetic blend. While conventional oils will only last about 3,000-5,000 miles between oil changes, full synthetics can last up to 15,000 miles (sometimes more). Synthetic blends fall somewhere in the middle at about 7,500 miles. Therefore, using a synthetic blend provides a step up in protection without breaking the bank.

3. Conventional Engine Oils
All conventional engine oils are initially refined from natural petroleum crude. With so many manufacturers switching to synthetic motor oils, you may wonder if it’s ever okay to use conventional oils. Conventional oils still have their place and can provide good protection under the right circumstances at a lower price.
Conventional oils are typically used in older cars and those out of warranty and generally cost much less than synthetic oils. Those who are diligent about timely oil changes can use conventional oil, if the owner’s manual indicates it is permissible to do so. Additionally, more frequent oil changes can alert a mechanic to a serious problem developing in an engine.

6 WAYS TO ENHANCE THE PERFORMANCE OF HIGH MILEAGE VEHICLES
Here’s a checklist to consider for helping keep older cars going strong even longer
In 2020, the average age of vehicles on the road in the U.S. rose to 11.9 years, according to IHS Markit. The older the car, the higher the miles, and the more problems that can surface. Luckily, today’s cars are built to last. Most modern vehicles are designed to drive at least 150,000 miles over their lifetime, and some can get double that.
With the proper maintenance and protection, you can keep your high-mileage vehicles running smoothly and reliably for as long as possible.
What is a high-mileage vehicle?
If a car has 75,000 miles or more on it, it’s considered a high-mileage vehicle. High-mileage cars require more frequent maintenance than newer vehicles to keep them on the road and performing at their best. Another thing to keep in mind is that a vehicle can be considered “high mileage” based on age, not just miles. Vehicles reaching the 6-7 year old mark can benefit from the additional protection of Kendall GT-1 Endurance High Mileage even if they still have relatively low miles driven.
Here are the top six maintenance tips you can use to enhance the performance and reliability of your high-mileage vehicles.
1. Change the Oil
It should come as no surprise that this is the first thing we want you to keep in mind. After all, if the engine is the heart of your car, then the oil is its blood. Therefore, the number one thing you can do to keep your high-mileage vehicles performing stronger for longer is to change its oil at the recommended interval and use a motor oil specifically formulated for high-mileage vehicles.
Why choose a high-mileage oil?
Just like any piece of machinery, as engines age, their internal components are subject to increased wear. High-mileage oils contain additives that take care of older engines, like seal compatible conditioners, antioxidants, detergents, and strong anti-wear or anti-friction additives.
Motor oils formulated for high-mileage vehicles have higher film strengths and viscosities that help them stay thick longer to better protect engine parts by eliminating the risk of metal-to-metal contact.
Kendall’s High Mileage Motor Oils are specially formulated with unique additives that may rejuvenate worn engines – this, in turn, may slow down the aging process of high-mileage engines.
Our premium quality, part-synthetic automotive engine oil specially designed to provide excellent engine protection for both turbocharged gasoline direct injection, conventional gasoline-fueled and flex-fueled passenger cars and light trucks under all operating conditions. It also is recommended for use in lower-mileage vehicles, including new cars under warranty. It is part of the Kendall ILSAC GF-6 product line.
2. Oil Supplement
The engine is the heart of the car. To keep it performing strong, give it a boost of protection with an oil supplement made especially for high-mileage cars. Adding an oil supplement to your motor oil helps to eliminate deposit buildup and protect the engine from corrosion. A clean engine results in less vibration, quieter operation, and better overall performance.
Our high-mileage booster has been formulated exclusively for use with Kendall GT-1 motor oils to deliver the added protection from sludge and rust that high-mileage vehicles need. So, your engine gets the protection it deserves and the performance you rely on.
The High Mileage Booster is a unique concentrated blend of key additives, specifically tailored for high-mileage gasoline-powered vehicles. GT-1 High Mileage Booster increases resistance to corrosion and helps to improve engine cleanliness. It is part of the Kendall ILSAC GF-6 product line.
3. Transmission and other Fluids
Fluids keep a car’s components performing correctly. Regularly check the car’s coolant, power steering fluid, brake fluid, and transmission fluid. Top off any that are low. If any are particularly low, it could indicate a leak in a hose or tank. Replace fluids at the recommended interval.
The automatic transmission system is one of the most complex pieces of equipment on a vehicle and keeps your gears changing smoothly. Maintaining the transmission fluid is important in high-mileage cars, because it keeps the system fully lubricated to avoid particle buildup and dryness that can lead to grinding, overheating, or breakage.
Our premium quality, full-synthetic transmission fluid is specifically designed for use in passenger cars and trucks with belt- and chain-driven continuously variable transmissions as well as step-type automatic transmissions. It’s engineered with unique frictional properties required for protection and performance across all three types of transmissions. With more than 1 million miles of on-road testing, it delivers proven performance in CVT and step type automatic transmissions.
4. Battery Care
If the car’s battery isn’t performing, the car won’t start. Keep batteries clean by removing any corrosion from the top of the battery and around the cables with a metallic brushed dipped in a mix of baking soda and water. Open the cover and check that the electrolyte level is at one-half inch. Add distilled water, if needed. If you won’t be using the car for an extended period, such as while on vacation, attach the battery to a voltage maintainer to keep it charged.
5. Check and Replace Filters and Belts
Keeping air filters clean by and replacing them when they are too dirty or old will keep your engine running smoothly by helping to ensure efficient combustion. While you are at it, check belts and hoses for wear and replace any that need it.
Tires keep the car firmly planted on the road. Bald, under-inflated or over-inflated tires, and road hazards can shorten the life of your tires, damage the suspension system, and create safety issues. Make sure to keep tires inflated to the correct pressure and rotate them often to prevent uneven wear. Check tires for nails and other hazards and fix any needed repairs. Finally, be sure and replace your tires at the manufacturer’s recommended intervals.
6 WAYS TO ENHANCE FUEL ECONOMY IN MODERN VEHICLE ENGINES
How to get better mileage and performance from your vehicle
While today’s engines are more fuel efficient than those in the past, there are still many ways to enhance the real-world fuel economy you get from your vehicle. A car’s weight, aerodynamics, resistance, drag, and engine performance all impact gas mileage. Choosing a fuel-efficient car, using certain driving techniques, keeping up with proper maintenance, and selecting an advanced motor oil formulated to meet the challenges of today’s engines can help you save money by getting more miles out of each tank of gas.
1. Use a motor oil formulated for modern engines
The push toward better fuel economy and decreased emissions has forced OEMs to develop more fuel-efficient, less polluting engines, which require more advanced motor oils that are specifically formulated to meet their unique challenges.
Modern engine design
Increases in fuel efficiency and emissions standards have resulted in smaller engines that use modern technology to improve mileage and reduce greenhouse gas emissions.
- Gasoline direct injection (GDI) and turbochargers work together to enable a smaller engine to generate the same horsepower as a larger engine.
- Stop-and-start technology allows an engine to turn off and on automatically when driving in traffic or high-congestion areas.
- Variable compression engines enable high efficiency and high performance of smaller engines at highway speeds.
These new engines require a more advanced motor oil that protects against the unique challenges presented by these engines, such as low-speed pre-ignition (LSPI), increased wear, and sludge formation.
ILSAC GF-6 and API SP standards
To meet these challenges, Kendall worked with the American Petroleum Institute (API) and original equipment manufacturers (OEMs) to develop a new standard: ILSAC GF-6 and API SP. These new standards went into effect on May 1, 2020.
GF-6 technology provides enhanced wear protection, prevents LSPI, improves fuel economy, and reduces carbon emissions in modern engines. It also helps OEMs meet their mandated targets for fuel efficiency and emissions.

2. Perform regular maintenance
Dirty air filters, worn out spark plugs, and bad connections can all affect fuel economy. Following your vehicle’s recommended maintenance schedule will keep it running more efficiently and produce fewer greenhouse gas emissions.
3. Keep tires properly inflated
A very no cost approach to improved mileage, improved handling and overall safety is simply keeping your tires at the proper inflation pressure. Make sure you have your tires checked for inflation pressure at every service. If you have concerns, most tire stores will check your pressure and give your tires a quick visual inspection for free.
4. Skip the warm-up
The old adage of needing to ‘warm up the car’ before you drive it is a holdover from the days of carburetors and doesn’t hold true for today’s modern fuel-injected, electronically-controlled engines. Engines perform most efficiently at regular operating temperature, and the fastest way to reach that point is to drive right after starting the car.
5. Slow down
6. Remove roof racks, cargo boxes, and bike racks
YOUR GUIDE TO CHOOSING THE RIGHT TRANSMISSION FLUID FOR THE JOB
Keep your vehicles’ gears shifting smoothly with the right fluid
The transmission is one of the most important – and complex – systems in a vehicle. It is responsible for literally making a car move by receiving the power from the engine, converting it into torque, and transmitting this rotational power to the wheels.
Transmission repairs are notoriously one of the most expensive and complicated repairs a vehicle owner can face. Therefore, keeping the transmission in tip-top shape and using the right transmission fluid is critical to the safe and efficient operation of any modern vehicle.
How does a transmission work?
The transmission uses a series of gear ratios to keep a vehicle’s engine spinning at an optimal rate (neither too slow nor too fast) while simultaneously providing the wheels with the right amount of power they need to start, move, and stop the car.
The transmission acts like a power switchboard for the car: It increases torque to accelerate away from a stop, prevents the engine from working too hard at highway speeds, and disconnects the engine power from the drivetrain to allow a car to idle without moving.
There are 4 types of transmissions
While manual transmissions are mechanically simpler, automatic transmission are easier to use. Instead of the driver changing gears with a clutch and gear shifter, an automatic transmission uses a highly complex torque converter and a series of computer-controlled gear sets, clutches, and brakes to automatically shift gears up and down. The complexity, number of moving parts, and computer system needed for automatic transmissions can lead to expensive repairs, if not maintained properly.
Automated Manual Transmission
Like a manual transmission, an automated manual also employs a mechanical clutch. However, the clutch is automated using automated using electronic, pneumatic or hydraulic controls. Sometimes referred to as a “Direct Shift Gearbox” (“DSG”) or a “Sequential Manual Gearbox” (“SMG”), this transmission allows for either fully automatic forward gear shifts or manual shifts through the gear selector or through buttons or paddles on the steering wheel.
Continuously Variable Transmission (CVT)
The CVT is similar to an automatic transmission, but it operates using a completely different mechanism. The CVT doesn’t have gears at all — instead, it uses a system of belts and pulleys to produce an infinite range of ratios. The car’s computer decides how to adjust the pulleys to create the optimal ratio for the particular driving situation. This makes CVT transmissions especially fuel efficient.
What does transmission fluid do?
In order for your transmission to work properly, it can’t have any of its metal parts grinding against one another. Similar to motor oil, transmission fluid acts as a lubricant between the transmission’s moving parts to facilitate smooth operation and to keep the transmission lubricated, clean, cool, sealed, and most importantly, to transfer power.
Typically, transmission fluid needs to be changed every 30k-100k miles, depending on manufacturer recommendations. It will need to be changed more often on cars driven in high-stress conditions, such as frequent stop-and-go city driving, towing heavy loads, or driving up and down hills regularly.
How to choose the right transmission fluid
Since the transmission is one of the most complex systems in a vehicle, choosing the correct fluid is critical to preventing damage and ensuring the maximum performance and fuel economy. Today’s modern transmission fluids are typically blended with synthetic base oils to offer better performance, with improved resistance to heat, cold, oxidation, friction, and shearing.
Here are the most common types of transmission fluids and what makes them different:
These automatic transmission fluids are the most common on the market and were designed and licensed exclusively by GM, Ford, and Chrysler. These fluids are formulated for the newest transmission technologies in today’s modern cars. They also can be used in many imported vehicles, according to manufacturer recommendations. All three include friction modifiers, which reduces the friction in lubricated parts.
