Customer Ratings & Reviews

I use amsoil in all my trucks. I've never had issues with it and it's still in pretty good shape after each oil change. It's worth the money if you like your car. Some people are fine with whatever they get at jiffy lube, but I am a little more picky with my oil. And this stuff has been proven good and it's got the reputation to match.

Offers great protection on my tuned Focus RS. I beat on this car everyday and have never had a single issue. Runs like a top day in and day out

Signature Series got me to 282,000 miles on my 2015 Chevy Cruze in 3 years driving Uber. I probably would have gotten a 100,000 more miles but I only started using Signature Series at 110,00 mile mark. It's the best. Anyone that really knows motor oil already knows this. My next new car will have all the fluids replaced with Amsoil products before the first 10,000 miles.

Good insurance great oil

Excellent product, nothing as better quality as Amsoil. Using Amsoil to all my vehicles. Nothing and is amazing!

Great product and great price need more for all my vehicles

It's engine oil. There's not much more I can say about it. It's one of the best out there. I noticed more of a performance difference from this oil than when I used Royal purple hmx so it's a thumbs up from me

Got 20mpg on my 98 3/4 ton 4x4 chevy pickup with this on the highway.

I have used Amsoil in both of my trucks and I have gotten the best gas mileage. I like the fact that I can go a lot longer than a standard oil change

I've used Amsoil products for many years. Zero complaints about the products or company.

Been using this oil for a while. Always looks good still even after a 10,000 mile routine oil change. Now I know I could go longer between oil changes but I personally don't like to. I run this oil in my Ram 1500 and my Dodge Grand Caravan. Love love love this oil!

I will only run this oil because other oils burn too fast in my engine. Amsoil on the other hand burns much slower and only have to add a quart after a long night at Mexico.

Excellent Oil. Have been using for 6 years, very happy with the performance

I've using Amsoil for so long now, I trusted this product and you can't find them on any chain store.

I switched out EVERYTHING on my vehicles engine, differential and tranny, piece of mind is everything. My vehicles run smooth, switch engine oil every 20,000, my mechanic was impressed with it aswell, he was a (full) synthetic user, but he drove my truck and he switched over immediately, again simply the best!

I am very happy to say that the oil is cleaning my piston rings and running my engine smooth.

Like the saying goes, "Quality is remembered after price is forgotten." Oil is the lifeblood of an engine, therefore use the best. This oil is, by far the best out of the many different brands I used in the past. It lubricates and cleans very well and resists burn-off.

After all the good reviews of Amsoil and using their grease, thought I'd give this a try. Engine is much more quiet with this oil and consumption is nil. I'll see about the gas mileage later, but I think it will be better. It was only pennys more than the M*****1 and shipped right to my door. I'm using a Amsoil filter this time, too. No leaks or any problems. Very pleased.

i have confidence i can go 10000 miles

Buying by the gallon seemed to be the best deal for my needs, shipping was several days earlier than predicted. Overall shopping with Amsoil is a pleasant, easy experience
