Customer Ratings & Reviews

I started using this oil due to the GDI turbo KIAs blowing up due to the silent knock/detonation inherent in the 2.0s. So far so bueno.

Short & to the POINT. I have been using AMSOIL for over twenty years , its the BEST, I have 3 vehicles & its the only oil I USE. OUTSTANDING OIL !!! SgtMaj

great oil for the high out turbocharged mustangs

I have been using signature in all my vehicles for awhile

Excellent product. Superior quality compared to other brands. Only issue is that that the vehicle kit comes with 7 quarts, when my vehicle only requires 6 quarts. 2023 Bronco 2.7

I have used Amsoil for 15 years. I have tried them all. Ansoil extends my change intervals by over 2000 mile on each change ( according to the truck computer) the only oil I use

Changed in April 2023. Engine seems to run quieter. Had to use pan plug gasket over again as forgot to have one on hand. Developed drip from plug but no other leaks showed up.

I use in several vehicles presently and are seeing good results.

I am experiencing wonderful results with this oil in my new car

This is the best transmission fluid out there. Your trans will shift better and last longer.

I had been used this oil for my Lexus Is250 2012. Also, for my Nissan Sentra 2012 model. There are no doubts about it, 5W30 signature series was and will always my picks. Thank you Amsoil !

This is Project Farms (Youtube) #1 oil for a reason! Great product in my opinion! Highly recommend Amsoil if you love your vehicle!

I started using this oil in 2019 and have never stopped using it. I love it and my vehicle loves it even more!

I have been using Amsoil products for over 20 years, From Gasoling, Deisel, and 2-stroke and 4-stroke. This is the best oil on the market. Been using this particulare oil, Signature Series in my wifes BMW, twin scroll turbo in-line 6 since new. I run it 10K miles changing the filter at 5K. Cost is about $100 per change. Car has 225,000 miles and runs perfect and does not use oil, maybe a quart per 10K which is nothing. I have never and will never have an oil related failure I can guarantee that. It may cost a little more but its worth it. All my friends ask me when am I going to become a dealer.

Finishing up my first 5k on Amsoil 0-20 Synthetic in my 2015 Lexus GS 350 AWD. I replaced front differential and rear differential at the same time as the engine oil. The car had 77k on it in September 2022 and is now right at 99k in early July 2023. While the car was serviced well according to records the differentials don't appear to have been changed. No real difference in drivability than before but simple peace of mind with good quality full synthetic oil. I have notice 1-2 mpg better in fuel since the oil change but could also be related to spark plug change out along with new OEM air filter. Car is in overall good condition but I would like to run it to 200k and believe Amsoil will be part of that.

Hands down the best Oil I’ve used. Noticed the performance and fuel economy boost. I will continue to run this oil/products in all my vehicles for ever 👍

I’ve used Amsoil Signature oil for years now in all my vehicles with excellent results. Engines keep running perfectly with seemingly no wear and never any oil consumption even with extended change intervals.

Been using it for years. Great oil. Tundra has 129k miles. Never misses a beat.
