When it's-20° below outside that's when Amsoil Signature Series really shines

317,000 miles. Change oil around 8000 to 10,000 interval.

Gives me peace of mind for ultimate protection! Best choice over Mobil 1, Castrol, Pennzoil, etc. Will purchase again

everything was fine

The best oil I have put in my vehicle, cleared up all my oil consumption issues and I haven’t had a 1qt low oil message in over 9,000 miles. I change my oil every 3500 miles but even on mobile 1 and mobile 1 extended performance my oil light would come on every 2000 miles. Hasn’t occurred since I switched.

I put it in my RAV4 crankcase. Some good stuffs.

Very delicious.

I've been useing this stuff for 6yrs now and in that time I've had 3 cars with well, 1 320k 1 460k & 1,200k. It's great oil and I've been doing 10k oil changes for oil to last like that it must be good. But I use there oil & matching filters. Had a Ford edge with 200k was sounding rough on start up, like a lawnmower when I 1st got it and oil pressure light was coming on changed oil with amsoil & filter and my wife's been driving it for months now and hums like a sowing machine now nice & quite. Also use it in my pride & joy my dad's old 73 Pontiac firebird formula with the original poncho moter in it. Great oil and is no higher than what's on the shelf when u set up your own account and so much better oil.....if u want to hit 400+k use this oil....

Engine seems to run smoother and quieter 👍

Only disappointment was I did not receive the promised gift of a telescopic wand.

For my new Subaru. May it last forever

Great product running it in all of my vehicles. Noticed a big difference in the performance of my vehicles.

Hope to have good results.

Very happy with purchase.

Very happy with purchase

I have been using amsoil products without fail on multiple vehicles over many years. One vehicle has 300 k miles and runs like new. Regular oil changes is key. I highly recommend amsoil products without fail- David northern Ohio

This oil is by far the best for my Acura MDX, and my CRV. It's amazing how much quieter the engines are after using the oil.

I change my oil every year in December, when my ford oil change light blinks. Great product, no issues!

Actually never used your product. Bought a car and the owner uses your products. They swore by it. So watching one of favorite YouTube person, and just out of coincidence he was featuring your product in a test and your product ranked the best. So I’m a customer of your company now. 😊

I am very pleased with the quality of the product. The delivery time always exceeds my expectations.....thanks!!
