Have been using Amsoil products on my vehicle for the past two years. I love the superior product they offer. Great customer service and I’ve always gotten a prompt response anytime I have had a question. My last order was stolen off my property and Amsoil shipped a new package very quickly for me at no cost.

Amsoil is the best out there. I’ve replaced all oil and greases with Amsoil.

My 2020 tundra serves me well, so to keep it in perfect working order I have had amazing results using 0W20 in the last four tundra’s I have owned and even recommended when selling my vehicles to the new owners to continue using Amsoil 0W20 Signature Series

This oil is the only oil I will use in a 2013 WRX which is in near new condition. And with this oil, I know the engine is getting the very best oil available.

Been with amsoil for 30+ years. Truly the best. Any of their products are fabulous and exceed expectations !!

I have been using amsoil for 5 decades and rely on it to keep my vehicles running for a very long time. My oldest vehicle is 39 years old with 400,000 km's on it and it runs like a charm even though I still push the original engine hard there is no sign of oil loss or burn, I trust Amsoil.

If you are keeping your vehicle for the maximum usable time this is the best way to insure it stays in the best possible mechanical condition and that comes from 35 years of usage

I'm always impressed as I drain the old out during an oil change, after 7 - 8K miles, at how clean it still looks. Very durable oil.

I have not yet used it but I will find a purpose for it. I ordered this by mistake , wanted the 5W20 oil. I have been a preferred customer for 15 years and and using Amsoil for 20 years. Was disappointed when they could not help out with return shipping charges.

great oil. i use it in my 2001 ford truck.

Use this in my 19 Toyota Tacoma. Runs quiet and smooth. Feel good knowing the protection of AMSOil.

This oil is fantastic. My 2.5 Turbo runs smoother and quieter and the protection is second to none. After 8,000 miles this oil is just like new in the crankcase. Yet I'm not surprised... my prior auto ran 425,000 miles without a single engine repair! I will always recommend Signature Series Amsoil..

Been using this oil since 1995. Did some modifications on my 1998 Camaro and there was no noticeable wear. All the parts looked brand new. I use this in my hot rod and both of my other cars. Simply the BEST

This is the best oil I’ve ever used,there will be no other oil that is going in my Heritage Softail!

This oil seems to be an elixir for my 115k mile F150 workhorse... she's running smoother than ever (I've run Mobil1 syn since new, until now). Highly recommend for your car or truck too!

very pleased with this oil ffelt the difference on my 2019 ram runs cooler and can feel the engine is quiter now after using this product

Amazing product, the advanced quality can be seen in the YouTube videos that compare Amsoil to other top oils, Amsoil way better after freezing, and heating. Now I want to buy transmission fluid for my cars and oil for 2nd car, and am frustrated I will not get the preferred customer discount for my first purchase.

This is my first time using the oil and filter but I will come back with a answer but one thing I noticed is that it is really quite

Good 👍

I have found that using this oil has reduced my oil consummation for my 2013 Chevy Avalanche with the 5.3 engine.
