This is probably the best oil ever used in my engine.

I use 0-20 in my bmw x-1 suv, and 5-30 in my wife x-5 they both perform perfectly even the bmw service dept said excellent choice, this speaks volumes for them as they ate the best techs out there Roadshow Bmw memphis tn

I have used this specific oil for 15 years,now on my Z06, Cadillac and Ram.

Product arrived on time as advertised. Quality, ease of pouring and the clear liquid level gauge is a nice feature. The engine seems to like this oil as there is very little engine noise while running.

Have been running the Signature Series 5W-20 in my son's 2015 F150 with the 5.0 Coyote since we purchased it last year with 148,000 miles. Ran the AMSOIL Engine Flush for 15 minutes before our first oil change with AMSOIL because I want the best protection. Seems to run quieter and hope to get another 150K miles, running all fluids on AMSOIL...

Great product and customer service.

I’m running a 2019 Sierra with the 6.2L. My truck isn’t in the recall range, but I still want to have the best oil in it. And my employer pays for my oil changes. I don’t like what I’m reading about the manufacturer’s reasons for using 0W-20/40 in these engines (gas mileage). So I’m using a thicker oil. I’m seeing zero difference in mileage since I switched to this oil, which is good.

After 20k miles still good

I change it every year less than 25k miles and the oil viscosity still good

I use this in every gas vehicle engine I own(5). I change it every 5k with and Amsoil filter & never a mechanical problem.

Works great

Arrived on time, works like it should have no complains.

Just started using in my Toyota Tacoma (very happy) I finally came around on my every day truck and soon my wife's car. I always use Amsoil Z-rod in my old Corvette and think I will be all set now will my oil changes.

On my third oil change since dealer oil change ran out. So far oil still looks good when changing at7500 miles. Light duty and light towing. Mainly highway miles minimal idling.

I started using this oil when my 2016 Silverado was 2 years old. I immediately noticed a difference in how the engine ran. Now, 8 years later it runs as well as the day I bought it

Works great in my 2024 6.4 hemi dodge ram 2500 4x4

When you use the best,your results are the best

1996 Tacoma V6 3.4 4x4, Truck is now 30yrs old and I’ve owned it 6yrs and from day one I switched it over to Amsoil full synthetic. Truck has 292k miles and still runs strong.

This oil is excellent—high efficiency and performance. I recommend it 100%.

Amsoil provides great quality products, always recommend !
