AMSOIL Synthetic 5W-20 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 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.
This is the 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!!

- Enhanced detergency to breathe new life into dirty engines.

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-20 Motor Oil is formulated to maintain viscosity, even in extreme temperatures. Many will often upgrade from a 5W-20 to a 5W-30 in older vehicles when they have issues with oil consumption but with this High-Mileage oil that is not needed.
- Synthetic High Mileage 5W-20 Maintains proper film thickness in extreme operation.
Sludge Reduction
AMSOIL 100% Synthetic High-Mileage 5W-20 Motor Oil reduced sludge by 67%, VV demonstrating its cleaning power that helps engines last longer and perform better.

Leak Protection! Yes – no other competitor uses a QUALITY additive for this because it eats profits
- Synthetic High Mileage 5W-20 Conditions seals to help prevent leaks. – Even the Signature Series is famous for reduced leaks
Oil leaks are an inconvenience and if left unchecked can lead to lack of lubrication and engine failure. AMSOIL 100% Synthetic High-Mileage 5W-20 Motor Oil provides a boosted dose of seal conditioners to restore aging seals and help stop leaks.
Note: Many higher mileage vehicles which call for 5W-20, especially those with turbochargers, the owners often go up to a 5W-30 for added protection if the engine has experienced wear. For that consider the High-Mileage 5W-30 or even 10W-30 versions.
