AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil

AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil

With rapidly rising new-vehicle pricing and the high cost of repairs, drivers are keeping their vehicles on the road longer than ever. Preventive maintenance that includes high-quality lubricants is key for keeping vehicles safe and dependable for the long haul. AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil is designed specifically for the unique demands of high-mileage engines (or engines which have been using oils which leave deposits like free oil change oils), helping extend the life of your vehicle.

This 0W-20 should be your first step to help clean up that engine w/o needing to use an engine flush.

It delivers purpose-built protection at a time in your vehicle’s life where it could benefit from more-robust maintenance. It cleans and protects engines with boosted detergency and an additive package that fights oil breakdown and oil leaks.

I suggest a couple changes with this oil then switch to XL or Signature.  This is a great choice should you buy a used car with over 80K on the odometer or that vehicle you really don’t know the history.

LOWER Cost than the XL Line!!

Engine Cleanliness thanks to our High Mileage Oil Line

  • Enhanced detergency to breathe new life into dirty engines.
  • Removes deposit buildup to help restore peak performance.

Cleaning Requires a Durable Viscosity

Engines can lose compression as cylinders and piston rings wear. This leads to reduced horsepower. Maintaining a consistent fluid film helps to counteract compression loss by sealing combustion chambers to maintain performance. AMSOIL’s High-Mileage 0W-20 Motor Oil is formulated to maintain viscosity, even in extreme temperatures. Many will often upgrade from a 0W-20 to a 5W-30 in older vehicles so this is your choice.

  • High Mileage 0W-20 Maintains proper film thickness in extreme operation.

High Mileage Synthetic Motor Oil Reviews

Great Oil

By  FRITZ,  a  Verified Buyer  on  May 14, 2024
Works as a great Oil to use to extend engine life. I use this in our Ascent and my WRX. Great Oil that I use in the winter for my WRX and year round in our Ascent. Always very little oil consumption between changes every 5k.

Great for my High Mileage truck

By  PAUL,  a  Verified Buyer  from  Aldergrove BC  on  May 11, 2024
I have 422,000kms on my truck still towing my quad around and it feels better after a yearly oil change.

Seems to be a good oil

By  Nick,  a  Verified Buyer  from  Michigan   on  May 10, 2024
Runs good in my 2017 Lincoln MKZ 3.0 Twin-Turbo V6 Not sure what else to say, it’s motor oil haha.

Switched to amsoil

By  JEREMY,  a  Verified Buyer  from  Maryland  on  May 05, 2024
Switched to amsoil about a year ago in my 2015 JKU . Since the change I’ve noticed better starts and smoother acceleration. And small gains in RPM and power in 5th and 6th gear. (even with the ac on).

The best Oil!

By  ERIC,  a  Verified Buyer  from  Ontario, Canada  on  April 14, 2024
I have been using Amsoil products in both my trucks for a couple years. Huge difference in quality and performance. I drive alot and no oil has kept up to how amsoil does. 10/10 recommend Amsoil products!
