Customer Ratings & Reviews

Use this on my Chevelle with an LSA engine. Works great. No oil consumption, quiets engine and just performs great overall. Ditched another brand made specific for LS based engines (not worth it and doesn’t perform like Amsoil). I’ll continue to use Amsoil from here on out.

I switched to full synthetic in Ford 5.4 engine a couple of years ago and it is still working great so far. I have only 135000 miles on it but it has the death tick so I know that it’s a matter of time. But Amsoil keeps it going.

I started using Amsoil in my 2005 GMC 2500 at about 65k miles. I was changing every 15k miles with no issues, and when I hit 160k lowered my interval to 10k. At my most recent oil change my mechanic said the old oil looked great. I will continue to use Amsoil in this vehicle and my next.

My 2016 Toyota Tundra crewmax 4x4 gets run hard. The heat in Florida combined with towing a trailer with 4 ATVs on it or towing my boat beats my truck down, but my amsoil 0w20 stays strong and performs amazing. Would definitely recommend.

My wife's car runs so smooth with amsoil. Her 2015 Hyundai Elantra was bought new and has had amsoil since the first oil change. Absolutely love it.

I'm satisfied with the performance of my 3.5 Penstar at 82000 miles and no problems which I attribute to a great engineered motor and AMSOIL.

Wouldn’t use it if it didn’t work as advertised!

Oil doing great, I’m on the 0-40 weight and did great on my 2,600 miles from Florida to Oregon in the summer peak month. Previously I was using AMSOIL in a different car and also did great in the deep winter in Chicago at -40 and started at ease versus other oil brands the engine would feel the viscosity is sub zero temperatures. cold climate

This oil ROCKS! In the harshest winter condition it facilitates easy starting in temps -30F. In the summer with 100F it maintains proper oil pressure. My last vehicle , (Hyundai Elantra, 2011) passed 425,000 without a single engine repair! I recommend this oil... when considering value... nothing else even comes close!

Had oil changed at regular interval of 25000 on 2012 Nissan Maxima and had internal diagnostic done and the mechanic told me he has never seen such a clean engine in his life. Asked what oil used and Told Amsoil Synthetic every 25,000 miles with Amsoil filter, he was impressed needless to say.

I use this oil and an Amsoil oil filter and when I get to 5000 miles my oil status indicator still reads 65% oil life. Then I change the oil. It runs cooler and the mileage is fantastic. I will use Amsoil products the rest of my driving life! Superior quality right down to the packaging.

Amsoil is synonymous with top quality. My 22-year-old truck with 213,000 miles insists on Amsoil, and runs like new.

For modern gasoline engines the 5W20 SS Motor Oil is superb in protecting the engine even in demanding operational environments. We get plenty hot in the summer in Texas, SE New Mexico, and this 5W20 SS Motor Oil holds up great. Multiple oil filter changes and topping off the crankcase is all that is needed for up to 20+K miles.

Have an 04 grand Cherokee with the 4.0 which are known for ticking and after using this oil the ticking stopped and runs smoothly.

Very good oil

I switched my 2011 f150 3.5 ecoboost over to the 5W-30 signature series oil about a year ago. I’ve been absolutely impressed with the results. I have gained 2 mpg and the engine idles better and I no longer have the hesitation I had before. Excellent product.

I ran machine bearing wear tests on all every popular brand of engine oil, including Amsoil, with 0w-20 spec; Amsoil completely dominated ALL its major competitors, leaving almost no visible sign of scarring on its 3 test bearings under approx. 10 lbs of load pressure for 3-5 minute durations. Every single other brand had a much noticeable scar. Amsoil’s bearing was also the only one I could hold in my hand without burning my skin. I’m HIGHLY impressed!

The only oil I use!

Other companies have followed Amsoil providing full synthetic. I have used Amsoil for 30 years in every vehicle. Never had an engine problem.
