Been using Amsoil Signature Series 5w20 for over 18 years and have been extremely happy with it. I go 15000 miles between changes and never use more than a half quart between changes. It's the BEST.

I use this in both of my vehicles; one specs 5W-20, the other 0W-20. It gets down to -15 degrees where I live in upstate NY and I depend on Amsoil to provide effective lubrication at temperatures where other oils struggle to perform. I generally put over 250,000 miles on each vehicle, and have never had one consume any Amsoil. Totally satisfied.

I have to use the best oil. The cost of not using Amsoil will put me out of business

I do 10k mile oil changes per Toyota, but this oil comes out still clean, not even black. I have no doubt I could use it up to 25k miles.

I've used this oil in my vehicles for at least 10 years and they have performed as promised.....also haven't had any leaks from the engine ....wouldn't change!

This is by far, the best product on the market.

My 16.5 year old truck still started in the cold Iowa winter when plenty of other vehicles even newer ones wouldn't. Have to give credit to good synthetic oil.

Every oil change gets Amsoil

Extended drain intervals, combined with my bypass filter, I'd drive this thing to the moon if I could figure out how to get it off the ground!!

Good cold weather starts

made a grate difference engine is quiet with a 10% better on gas can't wait for my next oil change

07 FJ cruiser with 150k miles, as soon as I dropped this stuff in, lifter rattle was gone

I've used this product on my 2014 Jeep Wrangler, I love this oil been using it awhile with no issues what ever

Hard To start very cold day

I use Amsoil oil, and fluids in all of my seven vehicles, from bumper to bumper, witch has cut way down on repair, down time and oil consumption..

Best form of lubrication for any automobile in my opinion.

I use this in my Ram Rebel 1500 and it keeps the truck running smooth.

I live a very cold climate. Temps sometimes get down to -30F with wind chils to -50 or more. My vehicles sit out side all year. I've never had a problem starting them, no mater the temp.

This is my first round of 0W-20 Signature Series for a 2015 Suburban as well as a 2016 Toyota. Paired with AMSOIL EA Filters, I trust the recommendations of the vendor. I've never had an issue whatsoever. Oil consumption using Signature Series 5W-30 on previous vehicles with over of 180K and 207K miles was ZERO. I loved the cold weather start and 1x/year oil changes (avg 17K miles/year).

I use AMSOIL signature series in my new Ford F-150 because the protection is great, the change intervals can be extended if necessary without lubrication properties breaking down. It conveniently shows up at my door via free shipping as a preferred customer.
