Customer Ratings & Reviews

I own a 2012 chevy Tahoe, it got 390 000Km on the odometer, I always ran good quality synthetic oil in it but the engine would always have a ticking sound coming from it. Since I switched to Amsoil high mileage the ticking went away and the engine feels more responsive, I will continue using Amsoil until the engine dies, I just regret not switching to this oil earlier.

This is my second time using AMSOIL. I’m not sure if it is the right one for my car . After changing the oil, the car makes a loud noise. I’m used to liking Pennzoil . So I am going to try AMSOIL for a few times. I’m hoping better . I like AMSOIL transmission fluid and gear oil.

I've been using this oil in my truck since the second oil change after I bought it. My truck is 17 years old now and still motoring along. This is good oil but then that's a known fact.

You notice a difference at startup that lasts throughout the life of this oil.

I boght Amsoil for my personal vehicle because it made me a believer! I did an oil change for a friend of mine an his car was mechanicly noisy. Th engine was so loud when we pulled it into th garage for th oil change. We installed a wix oil filtr boght from Amsoil an the z max oil because his car was a flat tappet engine. Aftr th oil change we started it up an th engine was so quiet we coudnt tell that it was running anymor! I will always use Amsoil products in my vehicles! True believer here!!!

Love this stuff.

Most of my used cars are with AMSOIL. I love the member price and when I do change it out. It seems to hold up the density nicely.

We have a camry we got for free that has about 300k on it. We drive about 300 miles a week with it and I had been using signature series but the 2.4 was consuming about 1 quart a week. I started topping off with this high mileage amsoil and after 5 weeks it has stopped or slowed down significantly in its rate of oil consumption. I'm impressed

switched up to this on my older f150 when i added a remote mount filter since it now takes 7 qts per oil change. the quantity is nice and will cover 2 oil changes with a couple extra quarts for the same cost as getting just 2 oil change kits and actually saving a few bucks

consistently does the job i need it to do. the truck that uses this on just about every oil change is rolling on 350k on the original engine as we speak.

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
