Signature Series holds up very well to the drain intervals recommended by the manufacturer (10,000 miles/1 year) even without an AMSOIL filter and with +5% fuel dilution in oil analysis reports. Honestly, I even think it has an effect on the oil life monitor, since it did not trigger a maintenance warning until about 700 miles left in the drain interval while a competitor brand triggered it at 1,000 miles left. I own a 2017 Volvo V60 Cross Country and use 0W-30 Signature Series instead of 5W-30 Castrol Edge Professional as recommended in the owner's manual (since the car requires ACEA A5/B5).

Hands down best oil presently on the market and I've used a few over the years. My cars run so much better. I also use Servere Gear in my SUV differentials which is excellent

I've been using Amsoil for at least 15 years. I started when my brother-in-law, an auto who owned and operated a shop of his own, turned me on to it. While I'm not personally sure about the benefits of the PI gas additive (I have no idea how to evaluate the benefits), I am 100% sold on the Signature Series synthetic motor oil and Ea filters. I have driven almost all my vehicles well over 200,000 miles, and had only one not go until I decided to sell it. The one that blew a head gasket on me was done in my one of my daughters, who at the time was a teenager learning to drive.

Smooth sounds is all to be said., very happy. Thanks

I finally stepped up to the best motor oil and I’m glad I did. Amsoil came highly recommended to me by a good friend who swears by it so I made the switch. This oil is the best out there. I can actually hear the engine running smoother after switching to Amsoil. If you want the best oil I’d definitely go with Amsoil!

I like the Amsoil SS oil in my sierra runs a bit quieter, most of the GM lifter chatter is gone. I used this SS oil in conjunction with the mobil 1 filters.

the only oil that keeps my 3v 5.4 ford quiet with 417000 miles on oe engine

The best oil I ever came across.

Engine runs more quiet, fuel economy improved, with overall increase in engine performance.

I have used Amsoil 5W-20 Signature Series synthetic oil for three years now. This oil was recommended by the manufacturer of Ram trucks as the synthetic oil to use in 2019 Ram trucks. This is by far the best synthetic oil that I have ever used. The oil is still very clean at oil and filter changes. I will continue to use Amsoil products!

I use the Amsoil Signature Series in all of my vehicles, (including a 2016 Ram 1500 Hemi, 2019 Honda Civic Turbo, and 2021 Mazda 3), except my 2021BMW 330i that requires Amsoil European synthetic. I feel better knowing the best is in those engines. Nothing is better than Amsoil. Checkout the Project Farm videos on Youtube to see for yourself. Amsoil may cost a bit more than some competitors...but my $165,000 group of vehicles is worth it.

Great motor oil

Fantastic oil. I use it in all of my vehicles. I didn’t get any stickers though.

I swear by Amsoil

I've consistently used 5-50 on my GT350 since its first oil change and have been extremely happy with the performance and results.
