I HAVE BEEN USING AMZOIL FOR OVER 48 YEARS IN ALL MY CARS AND EQUIPMENT. IT THE BEST OIL IN THE WORLD.

Awesome product and gives great protection

I didn't think my '08 AMG could sound or run smoother, but then I, on my first oil change, I used my much-loved Amsoil. Now the beast (as my wife calls her) purrs like a sweet 500+ hp kitten. I also noticed a small fuel mileage increase, and during the hottest months no oil consumption (as the prior owner had noted).

I have run the Signature Series in my Toyota Highlander (156000) and Toyota Tundra (88,000) since they were new. Zero mechanical issues plus increased fuel economy. Superior product! There is nothing else I would use!

ITS THE BEST OIL AND FILTER YOU CAN BUY. I USE IT IN MY CARS AND TRUCKS.

The stuff is amazing

I have heard good things when researching which oils to use in my Jeep JLU. I researched all the big branded oil and settled on AmsOil. I just replaced all the main fluids in my Jeep as it was right at 50,000 miles. I planned on only using the best lubricants available and in all my research AmsOil was one of the few top choices. I plan on doing all major fluid changes and maintenance on my Jeep, and will continue to use AmsOil lubricants going forward.

Keeps my truck running smooth.

I've run Amsoil exclusively in my car for the last 550,000km. Recently had to open the engine for repairs and my mechanic was amazed at how clean and wear free it was. Always use the best product possible, that's Amsoil.

Noticeably smoother engine after using the Amsoil. Used this in my 97 nsx with 136k miles on it. Car feels fantastic

I love using the best oil out in my new car. Only the best from it's 1st oil change on.

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.

Takes the abuse well and doesn't break down on the extended drain intervals, even with extreme heat situations

Excellent product as always. Can't say there's much improvement in fuel mileage as the viscosity of modern oil is basically thick water, but I have noticed a 1-2 psi increase in oil pressure over previous dealer installed oil. Truck seems to run "happier". Will give a better update on lifespan and any other positives at next service.

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
