AMSOIL’s 10W-30 Synthetic High-Mileage Motor Oil to Clean Your Engine for 7500 Miles

A popular upgrade for warn engines or anything over 75,000 miles which you may not know the history of.

The High-Mileage line is The Best Value Synthetic in Omaha

A super value 10W-30 comparing price to others in this class, when this is the minimum additive package in a quality line most cars need set at a competitive price. Excellent “Stepped-up” detergency not available in other oils in this class and it’s a true synthetic. You will know immediately when you first switch. And the best part it’s now in stock on 84th in our Omaha Amsoil dealer store! An excellent AMSOIL product to add to your shop too.

Our First Level Do It Your Self Synthetic in a 10W-30

This belongs in a blog but I’ll lay it out here..
So we have 5 tiers in all for gasoline cars. The lowest is a new semi-synthetic for lube centers to help them have a better product for all customers. The next is our OE which is also designed for service shops needing a premium 100% synthetic at a cost to retain repeat business. Then this – the High Mileage which is a full additive synthetic for those who want the best but don’t need competition or “enthusiast” level synthetics. This product has a longer drain interval and in two oil changes will clean up an engine in the time it takes the competition to do in FIVE!

Above this we have the Extended Life which is a top tier 20K synthetic for extreme heat and then our Signature which can withstand abuse dished out by the toughest driving and small sump turbocharged cars.. SO in summary this High Mileage oil overlaps 90% of all driving conditions and the tough demands modern engines have on the lubricant.

High-Mileage Synthetic Motor Oil Overview

AMSOIL 10W-30 100% Synthetic High-Mileage Motor OilPreventive maintenance that includes high-quality lubricants is key for keeping vehicles safe and dependable for the long haul. AMSOIL 10W-30  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!!

Cleaning Requires a Durable Viscosity. 10W-30 High-Mileage Has You Covered

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 10W-30 Motor Oil is formulated to maintain viscosity, even in extreme temperatures. Many will often upgrade from a 5W-30 to 10W-30 in older vehicles, so this is your choice.

10W-30 High-Mileage Synthetic Oil Reviews

 

Best oil
By  DONNA,  a  Verified Buyer  from  Taylor PA  on  August 11, 2025
My son in law got me started on this oil and it is now the only one I use. My car runs a lot better with it
Outstanding
By  CHRISTOPHER,  a  Verified Buyer  on  August 06, 2025
I have a 2018 Subaru Impreza. I was starting to get bad gas mileage around 145,000 miles. I switched over from using OEM oil and filter to using a wix xp filter with this oil and my gas mileage went back up significantly. Also, my engine sounds like it is idling more fluently and quietly again. I can’t say enough good about this product, I will be a life long AMSOIL customer.
