AMSOIL High-Mileage 5W-20 Synthetic Motor Oil

High-Mileage 5W-20 100% Synthetic Motor Oil by AMSOIL

High-Mileage cars or trucks which you purchased used, need this for one or two oil changes

New cars are no longer a popular option for more than a handful of reasons so buying used has its advantages.  High-mileage cars aren’t always bad but not knowing the maintenance AMSOIL is here once again for the rescue! AMSOIL 5W-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 left deposits), helping extend the life of your vehicle.

Preventive maintenance that includes high-quality lubricants is key for keeping vehicles safe and dependable for the long haul. So AMSOIL’s new High-Mileage line is here for that first step. Reverse that neglect. The additive packages and quality synthetic base in this formulation rejuvenate aspects of the engine via sludge removal and seal quality to enhance the reliability of the engine.

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. If you are already using Signature or XL than stick with those. This product is more of a first step or lower cost synthetic to compete for that 3rd or 4th vehicle.

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 5W-30 Motor Oil is formulated to maintain viscosity, even in extreme temperatures. Many will often upgrade from a 5W-20 to 5W-30 in older vehicles so this is your choice.

• High Mileage 5W-30 Maintains proper film thickness in extreme operation.

Effective Sludge Reduction

AMSOIL 100% Synthetic High-Mileage Motor Oil reduced sludge by 67%, demonstrating its cleaning power that helps engines last longer and perform better.

Customer Reviews on the High-Mileage Oil

Motor is smooth

By  CURT,  a  Verified Buyer  from  NH  on  June 08, 2024

Decided to try Amsoil over my go to royal purple. I am super impressed! No more valve chatter at idle

I was always skeptical of Amsoil, not in a bad way just a little concerned with cost vs actuality. But I got to say I can definitely tell the difference in the way my work trucks runs especially on cold start ups and colder weather in general. I’m sold… just from the way the engine sounds. Definitely a difference.
