Put this in a 2024 Frod Edge ST. Works great

I have been using for years on many vehicles. Worth every Penny

This is great you feel the difference in the perforance of the vehicle.

Amazing product can't wait to see how it performs compared to royal purple

Over 300,000 km and no problems at all with the engine!

I run this in a toyota prius C and a Nissan pathfinder. The pathfinder is direct injected and the oil you pull out of that motor looks aweful even at 5000 miles. People have complained for years about the 3.5 l gunking and sludging up as well, so I've been running this in her. I still do the 5000 mile intervals and it still looks aweful coming out but with less breakdown I'm hoping to avoid the sludge these engines seem to produce. So far I'm very pleased. In the Toyota it does great as well with its 6000 mile intervals.

Amsoil is the only product I truly trust. From their engine oil, their transmission fluid and gear oil. My 19 Silverado, my 19 Equinox and my beloved 2010 Camaro SS. Amsoil products flow through them all.

Turbos make great sense for us living at high altitudes. The AMSOIL Signature oils have the right detergent package to avoid LSPI and the shear strength to keep engines lasting a long time.

Amsoil is the best, best by far of any motor oil

A never fail oil/filter purchase. I run this truck hard in both work and play, Amsoil keeps everything under control.

This is the best engine oil I have ever used for my Dodge Challenger. Thanks!

First time using the Signature Series 5W-30 and I like it so far 2014 Ford Taurus SHO

Excellent oil. I have used for years.

Amazing has my Dodge Challenger scat pack sounding great, and running smoother then when I got it. Definitely recommended!!!

16 year old Lexus engine sounds quiet and runs smoothly 👍🏼

Truck runs better than ever

Products are top notch and customer service excellent and shipping is fast and dependable.

I put this in my 2021 Toyota tundra 1794, as well as aired the Goodyear wrangler (stock size) tires up to 47# rear and 50# in the front, followed by unplugging the negative side of the battery overnight. After I hooked the negative back up, I drove several trips using the sport mode(as soon as I put it in gear I bumped it up to 6th gear and left it. This allowed the motor to not rev up when slowing down. After a week of driving this way I went back to d and not sport mode. Result= the truck went from a steady 12 mpg or lower up to a steady high 15 mpg up through so far 19.+ on state route easier driving. (Looking ahead to let off the pedal at times coasting made more since to stop) avoid cruise because it uses the engine to slow the truck down so it waste fuel mileage.

Use amsoil in everything I own. One car with 5W-30 has over 370,000 miles, going strong.

Great stuff, it's expensive but I'm gonna buy it anyway.... 🤣
