I don't know of any other oil that will save an engine or prolong its life!

The best synthetic oil made....somewhat pricy but worth the extra cost.

I have a 2007 GMC Yukon four-wheel-drive with 230,000 miles. By switching to Amsoil vehicle went from 17 to 20 miles per gallon on the interstate.

Amsoil really stepped up and helped me out. I was one quart short on my previous order, so i ordered another full order for another oil change later to get an extra quart to finish my oil change. I placed the order on Monday and needed the oil by Wesnesday and they delivered. You rock!

We have used AMS oIl in our cars and have had no trouble with them. Will continue to use it

Using this oil in a Mastercraft NXT 20. Engine is a 5.7L MPI ILMOR engine. Simply the best oil I can put in my engine. Fast shipping and delivery!

I’ve been using Signature Series Oil for several years. It is the only oil I use in all vehicles! I have two Tahoe’s approaching 300k miles.

Makes my truck run smoother. I'm sure I'll see 250,000 miles now.

Just bought 2021 tundra ,when i get 5oo mile ,1st oil change with Amsoil 1000 miles change ,3000 ever after.

Hands down the best oil for 4Runners in my opinion. Whether you are in city traffic or over-landing, I’ll bet you sit still and idle for awhile. Just let that sink in a second…….

I have using Amsoil in my all my trucks for years and the just keep going and going and going

This is the only blood I will put in my truck. I plan to keep my truck a long time.

I have been using Amsoil products in ALL my vehicles & now children's vehicles for over 20 years. Best stuff on the market. First experienced synthetic oils in the Navy back in the early 80’s and thought there’s a reason for “mil-spec”. There’s a lot of synthetic oils on the market, yet none that offers superior protection like Amsoil. Living in the southwest where ambient temperatures can reach 115 degrees in the summer it’s nice to know my vehicles lubricants are top of the line.

I run this in all my cars and trucks, best oil on the market

Great product fast shipping!

My 2017 WRX, (not STI), rund like new and I've used Amsoil Signature Series since 10,000 miles. I have 68000 miles now and while I change the oil every 3000 miles due to modifications, 368 WHP measured on the Mustang dyno, it never misses a beat. Sure, it's expensive, but so are all the other boutique oils out there such as Motul, which by the way gets beat hands down by Amsoil in independent testing. There just isn't another oil with the proof to back up the claims like Amsoil, is there? If so, please do tell!

Best oil ever that I’ve used in my Genesis.

Always run Amzoil

Have used AMSOIL products for over 30 years.Would not use anything else. Use in trucks to incude diesel,cars,small equipment, 2 cycle engines and other types of equipment with great sucess.

The product is 2nd to none
