Just started using High Mileage Oil so we will see! Amsoil is great, so no worries!

I recommanded this product to any body good oil

Great good oil

With Ams Oil I have more confidence in my vehicle lasting longer every time I change the oil.

Fast shipping great product

This is the at least the second time I've purchased and used this oil in my 2018 Silverado 5.3l engine with over 75,000 miles. To date, I am really satisfied with my purchases using the products from AMSOIL. You should to.

I use this in my 2014 Jeep Wrangler and it's always been great to use

2020 renegaxe 2.4 performed way better just by changing to amsoil. Mpgs went up more reponsive pedal ...will do all our cars with this oil in the furue! Tks

Purchase of high mileage product is in anticipation of next oil change. Anticipate same quality as previously purchased products

I love the signature series, oil and filter that goes with it. However, the filter has been out of stock for several months with no update on when it will return. So I suggest not buying this product until the filter is available.

Great product really works. Also came in perfect timing.

I switched to Amsoil a couple of years ago and all my vehicles run better on it.

I have used amsoil in all my vehicles for quite a few years, I believe it has extended the life of the engines. Great product.

Really high quality pruducts and quick delivery. I'm glad of being Amsoill customer

in all my toys and cars never let me down......totally reliable products

Noticeable improvement compared to other synthetic oil.

My review ,Smoother sounding motor ,knowing I'm doing the best for the motor and the love for my Truck to give it the best

since i have been using Amsoil 5-30 engine oil in my truck i have had no issues with low oil pressure which most garages use a cheap part synthetic motor oil which breaks down fast. So happy to have switched to amsoil great product my cost a bit more but it saves you money over the long haul if you want to keep your engine in top shape. Also my garden tractor would smoke every time you started it up but since i put amsoil small engine oil in no more smoke runs better and doesn’t use any oil. Thanks and i’m spreading the news to everyone i know, keep up the great work customer for life

I have tried many oils for my trucks, including the Royal Highness lol but honestly Amsoil has been the best I currently have 200,000 miles on my 2020 jeep and I truly believe the oil is keeping the engine running stronger then ever. I will continue to run Ams and constantly recommend it

Great stuff
