This oil is worth the extra money, to protect the ridiculous amount of cash,We pay for our vehicles. Amsoil has never failed me.

great products, worth the extra $ for the piece of mind.

I ordered oil and a filter to change the oil in the LS3 in my C-10. It was shipped quickly and the gloves, filter and oil change sticker were a nice surprise.

Been a loyal user since the late 1980's and haven't used any other oil.

Great motor oil, helps with performance, it's a high end motor oil so you pay a little more. If you order the Jug it's 4 qts not 5qts. Amsoil is easy to order on line and fast delivery. They have a customer service and a tech cs too.

Was a bit skeptical like any other person when hearing Amsoil since some people say it’s overpriced and not worth it. Let me tell you something, haters gonna hate. You get what you pay for in this product! It’s crazy to say but swapping from oem to signature series on my wife’s 23 Explorer 3.0 with turbos, the motor idles smoother and quieter. It just feels and sounds more lubricated with less friction. Hoping this oil can take my 3.0 to last for years to come!

Best there is

I never had a single lubrication/valvetrain issue since switching to this stuff

Excellent product

Great oil, car runs great

The product is of exceptional quality and the service is excellent.

I use the 0W-20 Amsoil Signature Series Synthetic Motor Oil for both our Cars.

Purchasing 3 new Twin Turbo Fords in the last couple of years thru investigation I switched directly to Amsoil from the dealer installed Motorcraft oils. I am a meticulous car person and keep vehicles for the long term.

Excellent, have used a few times now in a modified supercharged hemi 5.7. Working great thus far.

Good oil. Works great in my tundra.

I have been a dedicated Amsoil customer for quite some time. All of the independent studies I read confirmed a significant performance difference compared with other products.

Sure, it's great oil going in, but the magic is how well it comes out when it's done. This oil holds up better than anything. I use it in everything - daily drivers, weekend cars, etc
