AMSOIL is a perfect High Mileage Oil.

Engine oil has been called the lifeblood of a car. An engine runs smoothly, almost effortlessly, when the engine oil is full and clean. Hundreds of moving parts work in perfect timing to produce raw horsepower and torque. But take away the engine oil and – well, everything stops.

Engine oil serves several purposes in an engine. It helps carry away heat that builds up, reduces friction inside, washes deposits from internal components, prevents wear on moving parts, and protects against corrosion.

In a high-mileage engine, the oil is even more important, and without the proper oil and oil changes you could be facing engine problems. Wear and tear has created space where there previously wasn’t any. Seals and bearings have some pitting and wear, and minor leaks are developing.

But with the right engine oil alone, many of the symptoms of a high mileage vehicle disappear. What is high mileage oil, and what is the best motor oil for high mileage engines?

What High Mileage Oil is All About

For most people, high mileage oil isn’t typically a concern. They’ll use whatever the quick lube shop has on hand. But it’s proven that you’ll get better performance, reduced wear, and longer engine life when you choose the best motor oil for well-used cars. When you’re choosing the best oil for older cars or high mileage engines, there are several criteria you can look at.

Engine Age

Engines can be considered high mileage at 75,000 miles and up. Or, if your car is 7 years old or more, it’s a good idea to look for an oil with the best viscosity for high mileage before your engine starts failing.

Viscosity and Temperature

Look for an engine oil that tolerates high temperatures and maintains its viscosity – that is, its ability to protect at high temps.

Climate

For cold-weather climates, the first part of the oil rating is important. In most temperate climates, a 10W oil will suffice, but the best motor oil for high mileage engines in cold weather will start with 5W or even 0W.

Additives

Check for additives that clearly spell out the oil’s protective qualities. Many high mileage oils contain detergents, seal conditioners, friction modifiers, and antioxidants to keep everything neat and tidy inside.

Budget

You’ll find a wide range of high mileage oils on the market – synthetic, semi-synthetic, and conventional. Prices vary by brand and grade with synthetic being the best and most expensive for obvious reasons.

High Mileage Oil

High mileage engines often lose compression, the gaskets become brittle, the rings wear and valves do not seal as tightly, increased oil consumption, reduced fuel economy, decreased performance and more rapid oil breakdown. However, these problems can be avoided by running a high quality synthetic motor oil. By using a premium synthetic from the start, these problems would be minimized or cease to exist in the first place.

Benefits such as these are nothing new for our customers. All AMSOIL motor oils effectively condition seals, keep oil consumption to an absolute minimum, resist oil breakdown and deposit formation and permit easy engine cranking and quick starts in the coldest temperatures, all while keeping friction and wear to a minimum.
