I have been using this oil for over 10 years and it keeps the internal parts of my engine clean and it performs well. No oil burning and no leaks. Highly recommend.

After making the switch from Mobile 1 and then later Royal Purple let me tell you, my sports car runs so much better. I can tell the difference in throttle response, there's less vibration, and my car sounds better too.

have used only this oil in my vehicles for 20 years. my old ford escort had 400,000 miles on it when i sold it and still ran great.

Been usin Amsoil on all my vehicles but recently switched to Amsoil on my 2019 Type R. Currently tracking the Type R with Ow-20 signature series noticed no issues with the oil. Thanks Amsoil!

I had my engine opened up at 341k to replace the water pump. It looked like a brand new engine inside, no gunk or carbon deposits anywhere to be found. My mechanic couldn't believe it. I love and believe in Amsoil's products; and wouldn't drive a vehicle without them protecting my investment.

I believe this oil to be the best,it is proven and I don't believe it can be beaten .Pure synthetic oil is the way to go these days and amsoil signature series is the oil you should use if you want protection.

Very easy cold start Rev smooth

I have 5 vehicles none of them drove over 15000 a year so now I just change oil once a year in all of them in December and it comes out cheaper than using conventional motor oil and not as much work

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.
