Customer Ratings & Reviews

I've used this on my highly modified SRT-8 for 8 years. Great oil.

I put this in my wifes car and noticed a big difference in mileage and power.Best oil on earth.

I have not used it yet. My purchase was a preemptive strike. I bought a new car for my wife and when its interval comes up I want AMS OIL in it.

Best oil I've ever used. Truly great product that keeps my supercharged heel srt8 running smooth

Overall a good oil. Time will tell and I'm sure it will be in amsoils favor like every other product they manufacture.

I have had my car for 12 years and put 220k miles on it. I have also sent my used oil to a lab for analysis in between my oil changes. When I was at 200k miles I had to move a lot for my job and couldn’t find Amsoil so I used a different brand synthetic. Before I did that, even at 200k miles my car had no oil seeping from anywhere. You could eat off of the block. Within two oil changes of a different brand I started getting oil seep from gaskets and seals. Two Amsoil oil changes later and the seeping has stopped. The lab has always commented on how my motor is wearing significantly less than comparable motors. I also beat the crap out of my car and have seen the drag strip many times. I have no worries that with Amsoil products every vehicle I own will go 300k miles plus.

Received my order quicker than expected

I’ve been using Amsoil in both of my trucks. I have a 2002 Tundra and a 2016 Chevy Silverado. I think Amsoil is the best oil you can buy. Both trucks are running great. Neither burn a drop of oil.

I have been using this oil for many years , and I would not ever change to another brand! Out beats all the other brands.

This was the last chance before I replaced my cam and all my lifters in my 09’ 5.3l. With only 106,000 miles I did not want to do that job. My motor would tick on some start ups and always when it was hot out. This Amsoil and the Amsoil motor and trans cleaner quieted my motor right up. I always skeptic of Amsoil’s claims but have seen enough studies to say they mean what they advertise. I’ll be an Amsoil customer for life now. Thanks, Amsoil!

Best oil I have ever ran in my vehicle, gives me a higher level of confidence than any other oil.

Will never use another oil again.15 out of10

I started using your Signature Series Oil in my 2010 Ford F-150 SVT Raptor for the last three oil changes. I've seen an average Fuel Mileage increase of 2 MPG. Because of this performance, I've just started using Amsoil in my wife's Ford Edge. I expect to see fuel mileage gains in that vehicle also. I've experienced the benefits of Synthetic Lubricants and have used them in all my machinery for many years. Very happy with your product and your On-Line store.

love using this oil. nobody has a super great time changing the oil every few months like in the past with regular oil. with this about once a year I make arrangements to get it done.

There is no other oil I will use but Amsoil!! I’ve used it at least 30 years! I’m a retired Firefighter, even when it was 30-40 degrees below zero my vehicles always started when the pager went off. I use Amsoil in my Pickup, SUV, Outboard motor, Lawn Tractor, and Snowblower. It’s always has done an Outstanding job for me.

Amsoil is the only oil I put in any of my vehicles

The best way to treat your car or truck.

I’ve tried Mobil 1 Full Synthetic and Chevron/Havoline Full Synthetic. Both oils would give my engine just a little tick on start up when it was below 30 degrees or so. No tick so far with the Amsoil. The lowest temp so far has been around ten degrees. Very happy with this oil.
