I’ve been running Amsoil in my S-10, Astro Van, 1987 Harley-Davidson ( bought new myself), 2005 Peterbilt, Wheelhorse 312-8, chainsaws, lawnmowers, and snowblower. I am more than happy with Amsoil products. I use Amsoil grease as well. The newest machine I own is the 2005 Peterbilt. I highly recommend their products.

High mileage goals with the right product. I protect all my vehicles with Amsoil. The proof is in the oil analysis and longevity I get with my vehicles.

Great oil for a high mileage vehicle

This is a good oil and the containers are convenient. The company ships quickly with very good packaging.

Couldn't recommend Amsoil stuff more. I've been running Amsoil in every car I've owned for the past 15 years. Old cars, new cars, cars that have never seen synthetic oil before, etc. Haven't had an issue I can point back to synthetic oil, but I have gotten some engines well over 300k with nothing more than regular oil changes with Amsoil. Check it out, get it while you can, you won't be disappointed.

Order and delivery accurate and on time.

I have been using amsoil for 20 + yrs. It's the only oil I use in all 4 vehicles

Love this product

Everything I own goes well over 300k miles before I sell it. Amsoil always!!!

I am an automotive technician and I know the value of a high quality oil and keeping up with maintenance. Changing your oil is the cheapest way to keep your vehicle running strong and efficient. I have bought AMSOIL 0W-20 Oil for the past several oil changes on my car and it only continues to keep my engine running strong. I always recommend AMSOIL to customers and friends for high quality product with endurance. Will continue to service all my vehicles with AMSOIL products to ensure longevity and performance from my vehicle!

Been using amsoil for long time, 2 trucks, tractor an 4 wheeler. Good stuff

Went into a 2025 Subaru Wilderness turbo.

I've been using this extended life in a couple of my cars that don't get a lot of miles put on them. Change it once a year and all is good.

Great stuff

Lovin' the longer change intervals. The car has been using Amsoil since it's second oil change .Had the valve covers off to repair a leak , amazing how clean the top end is after 245,000 km. Engine runs great with no problems .

I put this in my 1995 Subaru Legacy with 232,000 on it and the engine purses like a kitten. Runs great on the highway.

love the price and not having to change oil as often.I run it 10000 miles or i get two changes out of it

I used Amsoil in my ZO6 ever since I had power additive on motor. This oil works wonders for me. Keep the beast lubricanted well.

Great oil and filters always have everything I need for all my vehicles super fast shipping I highly recommend.
