Have been using oil for couple years car is quieter at idle speed and runs smoother.

New to me Equinox 150k. Seems to run smother.

I like how they have the proof behind all of their products and that to a consumer adds trust and value knowing that it truly is protecting their engine in their vehicle

Oil pressure one up when switching to this oil

I have used the synthetic oil in my autos since - a long time ago! I wouldn't use any other oil in my auto.

This is a great oil. I am still working out the needed viscosity for my build. This was the recommendation from the Amsoil Tech department and is a great choice! I will be testing the 5W-50 soon and may go with that one for the more oil pressure registering on the gauge.

Hands down best oil ever i have used in my life. Great quality better than any other oil on market . Oil doesn't turn black on me like others

Great product - service is excellent. Very easy to order and very fast deliveries.

It’s just great oil!

2007 Hyundai Elantra. Original engine. 400,908 miles. Have been using Amsoil Signature Full Synthetic 5w-20 for three years now. I like this oil.

I was happy to see that my order was shipped quickly ad arrived earlier that promised. The order was complete and came with a useful pair of gloves and a disposable funnel. The oil should be as reliable as advertised and my only doubts are about the filters. The oil filters looked like cheap knock offs to be honest.

always use amsoil, it is the best oil for my car

Brought this truck new in 2014 every oil change has been with Amsoil Signature Series. Runs great no issues, no lifter problems that many of the 5.3 engines have. Not only do I use Amsoil motor oil in all my internal combustion engines I also use several of their other products which are great.

Had oil and filter changed from Ford Synthetic to AMSOIL. Engine ran smoother by the time I got home (3/4 mi). Went to event 2hrs away next morning. Round trip (4 hrs) saw 2mpg improvement. Phase 1, crankcase, is done. Phase 2: transmission, transfer case, and differentials next. Lastly: coolant, power steering and brake fluids.

Ok, long term review, one of my vehicles is a 2007 Tahoe (5.3L), I started using the Signature Series about 100,000 miles ago after the vehicle already had 150,000 miles on it. Upon the first change I noticed a difference in oil pressure, the dreaded GM cylinder shut off system and lasting longer between changes. It's still running well after 260,000 miles and I have hope for many more miles. I only wish I had started sooner with this product.

Great oil, easy fast shipping.

What's there to say it's just good oil!!!

It’s a great kit. The 1 gallon containers are great compared to the competitors 5quart. Everything you need with one click. I just started using AMSOIL in my truck this year after using Mobile1 for years. It’s a bit pricey but it’s piece of mind knowing your using the industry best in your engines. I’ve also started using it in Briggs&Stratton home standby generators as the air cooled models can run very hot.

This oil is the best! Vehicle runs great and oil packaging is perfect.

I switched to amsoil after I spun a rod bearing. Right off the bat I noticed lowed oil temps when driving around using the same weight as the past stuff. The car idles smoother than before.
