Customer Ratings & Reviews

With 227,000 miles on my 20212 Camry I could feel and immediate smooth engine after switching to Amsoil. Highly recommend, can go wrong!

I used amsoil XL when was 12k miles and now that switched to higher and the High mileage is still 12k miles and hopefully since my vehicle is above 75k that it will give that added boost we all have trusted amsoil with and will use til my vehicle decides to no longer be

First time using on high mileage car. So far so good. Time will tell but I have high hopes.

Have been using Royal Purple for many years. When I saw the performance improvements in the laboratory results, it’s a no brainer. Amsoil from now on!

I only use Amsoil my prior 2000 Ford Expedition went $366,000 MI on the original engine it was never opened or ever touched. It was running fine when we sold it we no longer needed a four-wheel drive expedition in South Carolina.

This 4.7 V8 with 282,000 miles runs like a top. But it’s even better with 5W-30 100% synthetic high mileage oil.

Best oil I have used for my daily driver. Engine runs very smooth. 4.3 liter vortec with 254k on it

Best on the market

Great product

Well the car has 180,000 on it so I decided to go high mileage. Oil and filter are done so now we wait and see.

I've been using this oil in my truck for the last year. I have noticed a big difference when towing the racecar. Even after 5000 miles oil still looks fresh. Engine has been running smoother since switching to Amsoil. I use Amsoil not only in my daily drivers but also in my racecar. Great products.

It’s helped slow down the oil burning issues with the 2az-fe engine. Never got a recall for this engine from Toyota and been meticulously checking the oil more often than most drivers do. Have used various brands like Mobil 1 to the cheap Quaker State conventional oil to monitor my oil burning problems. This product definitely slows it down. Been ordering it consistently since introduction by AMSOIL. Was using Signature Series prior to this and it didn’t help with the oil burning issues as much as this one. I still do oil changes every 3K just because of the oil burning issues. Oil is inexpensive compared to a freezed engine with no oil in it or blown engine with no oil in it. It’s worth it. Currently almost 260K miles on this badly designed engine!

This is the best engine oil on the market. Much better performance using this product. Unless something else comes out better, I will be a lifelong customer.

Good price, highly recommend for any high mileage vehicles to know this oil will protect your engine, especially during cold climates

👍

This has to be the best lubricant I’ve ever used, fixing to swap all my equipment to it!!!

Amazing oil. Super high quality and always packaged with care!

I have used Amsoil in all of my vehicles and have been extremely please with its performance. I have three high milage vehicles including a 1930 Model A Ford in which I use their high Zinc 10W/30W Oil. I am extremely pleased with the quick delivery and lubricating properties of the AMSOIL Products.

I love the fact the kit comes with everything, oil, oil filter, GLOVES, FUNNELS!!

I’ve been using this product about five years and it’s very great. I will not change it for another. I’m very happy with it and I will recommend it.
