High Mileage XL Series Synthetic Oil Change

Keep motoring with an AMSOIL high mileage oil change.

You love your car. After years of ownership and hundreds of thousands of kilometres, you don’t have any plans to replace it. But owning a high-mileage car can be fraught with expensive repairs if not cared for properly. Fouled spark plugs from oil consumption, worn internal components from friction, and oil starvation from sludge-blocked oil galleries can change your plans and force your car into early retirement.

Routine oil changes using AMSOIL’s XL series oil for the best high mileage oil change can extend the life of your engine and potentially reverse some of the symptoms you are experiencing.

What exactly is a high mileage synthetic oil change? It varies according to a vehicle’s use. It could be 20,000 km of hard city driving or 200,000, 500,000 km, or more of a city-highway combination. Whether your vehicle’s clock is threatening to turn over or you expect to drive it until it does, choosing the right oil is imperative to prevent unexpected and unavoidable issues. Use the AMSOIL XL series for the best oil for high mileage in these situations. It contains higher quality additives than the competitors like Mobil 1 high mileage and Pennzoil high mileage oils. AMSOIL XL Synthetic oil with boosted additives ranks at the top of the class. And what would you rather have – the best high-mileage oil or something barely above average?

Symptoms of high-mileage vehicles

Does synthetic oil fix oil consumption issues?

If you drive a high-mileage vehicle, a typical symptom is that they can burn oil, simply due to worn cylinder walls and piston rings. Microscopic gaps allow oil droplets into the combustion chamber where they burn, contaminating the fuel injectors, spark plugs, valves, catalytic converter, and more. The mechanical correction required is expensive and time-consuming – tearing apart the engine and replacing worn parts to restore tolerances to like-new. But who has the time or money to deal with that frustration?

A high mileage oil change doesn’t correct the wear and tear, but it can reverse the symptoms either partially or completely. The uniform particles can often provide a better seal between the piston and cylinder walls, minimizing the amount of oil that can slip past. It can even help wash away soot and carbon that’s built up inside a high-mileage engine.
