Customer Ratings & Reviews

I had to settle for the high mileage instead of the signature blend which is my usual oil. But I've been running it now for about a month in my daily driver (Ram 1500) and I do anywhere from 50-100 miles a day. Steep grades, mountainous highway driving, high desert heat upwards of +100°. And this oil has performed better than any other "synthetic" oil you buy at one of the generic parts stores. I don't notice a big difference between the signature series and this one, but I like them both and so does my truck. Last oil change, my oil still looked like it had plenty of life left in it. Which is a good sign. And when I added the new oil (high mileage series) it made my engine run so smooth and quiet. Can't wait for my next oil change when I go back to the signature series! Amsoil for life!

I’ve used this oil for years and I have never been disappointed with it

engine knocks a little with this oil, i put in valvoline max life 10w30 before but never had any knocks!! ?

I run this in my o3 Dodge Ram with no problems.

So far the oil is running good inside the engine there’s no check engine lights or anything.

Best oil for my 2003 Silverado rolling up on 100,000 miles!

5 star

Great product like always!

I have over 400,000 on my GMC Sierra, and this oil outlasts the rest. I have recently changed my wife's vehicle to AMSOIL. She has over 100,000 on her Buick Encore.

Heard about this stuff while working in the auto industry from a friend who swears by it. Did an oil change in my garage at home with this stuff and it appears to be working great so far. I have a 2016 Chevy Silverado 1500 w a 5.3L V8 and it is running VERY smoothly. A little expensive but I know that quality comes at a price. I used the high mileage oil because my truck is at about 95,000 miles. They claim this stuff last 12,000 miles or one year but I will not let it go that long. No complaints, seems to be a great product!

It's the only oil that I put in my 08 6.7 Cummins. The engine thrives, shows 0 leaks, and runs like a sewing machine with 226K miles.

It’s so easy to reorder my kit for my truck and cars. My rep has helped me anytime I’ve needed it. Yes, Walmart is cheaper, but ask anyone in the whole store a question about what’s best for you car and no one can answer you or show you the facts. Walmart doesn’t deliver in my area and I would be weary if they would pick the right products in the first place.

I currently use this in a 2015 Toyota rav 4 with 122,000 miles. Been using the high mileage oil ever since the vehicle had 75,000 miles. The vehicle sees a lot of short trips. The vehicle doesn't "use" oil(not adding an extra oil) between oil changes. In one year we usually travel around 10-12,000 miles

I have found that Amsoil representatives have exceptional people skills. In addition to that, their oil quality is the best!!!

Great price for a great product for your vehicle!
