There are no other decent high-quality 20W50 oil products around for this price. Cannot think of a better value, at least on West Coast. Engine runs just as dependably, even out of a tire slide, as when brand new.

The filler spout is too big to fit all of my bikes cars & trucks. Like the oil.

I have never regretted the day I made the switch to AMSOIL products. I am currently using the 20W 50 Full Synthetic in my Race Engine 4AGE 20V Turbo Charged. Engine Runs way smoother, even the initial startup in the mornings is way quieter. I have recently Purchased there radiator Coolant and I am eager to have this installed. I am Happy, and Highly recommend AMSOIL Products to anyone who wants to protect there machinery, equipment or motor. A++ AMSOIL For LIFE......

Use this in my John Deere Diesel engines as well as my Chevy Trucks

The heacier weight oils are to die for if you own a rotary engine in a warmer climate. Amsoil delivers when it comes to their 20w50 synthetic oil.

I am using this oil in my 68 Charger. And I am very happy with the results.

Have used Amsoil products (used to sell it) since 1974 in all of our better vehicles and farm equipment. With annual or semi-annual changes of engine oil, never an issue related to lubrication and sludge or varnish buildup is a thing of the past.

good oil

Made the switch from conventional oil to Amsoil and appreciate the quicker startup, better throttle response & quieter engine operation on my 94' Discovery. 340K km on the clock & looking forward many more with Amsoil. Thanks for a great product & service!

I have been using Amsoil in my cars that I drag race for 12 years...never an issue....Amsoil is by far the Gold standard of motor oils .

This oil has a very strong cleaning aspect. When I drained the oil the first time I used it in a motorcycle with 17000 miles on it, it came out looking like thick almost gloppy molasses. Very black and quite thick. Subsequent oil changes have resulted in the oil coming out much cleaner. So much so that I can see light through the stream of oil as it is draining from the engine. I recently removed a side cover to inspect the clutch plates. The inside of the engine is clean like it was new. I'm very happy with this product.

I am using this oil in my 95 GMC Sierra SLE. with a V8 5 litre. The oil makes the engine run smoother and quieter. Gas mileage seems better. The gas needle doesn't drop as quickly. I have been using it for 2 months. so far no leaks, no oil consumption. Acceleration is good.

I use this oil in my high mile Plymouth with 175k miles on the engine without any trouble with lots of highway miles. thanks

I run AMSOIL 10W/40 in both vehicles a 2006 Tundra Limited, a 2012 Dodge Caravan and my John Deer 300X Riding mower and in every vehicle I have owned over the past 40 years. When 50w AVOIL was available I ran it in my 1977 Cessna 172N.

Put 7qt. in my 68 Charger and I am very happy with results.

Not the cheapest, just the best. After tearing down my motor after 250hr for rebuild/refresh, my rod, cam, and crank bearings still looked new. Keep in mind this isn't a pampered motor. It gets run hard, yet the rebuild seemed completely unnecessary.

I have used it in my durango for years.It is a great synthetic oil

I love the piece of mind knowing when I crank up my truck in the morning there's no dry starts

I am a firm believer in Amsoil. This oil helped me out with my 75 chevy 350. It took away an engine tick. It also runs and idles a lot smoother. Excellent product.

i love the product , i drive less then 12,000 miles and so i have been changing my oil once a year , since 2007 when i overhauled my dodge diesel engine. in fact it's cheaper then running Dino oil ,.. and changing it every 3,000 ~ 4,000 miles. thank you for the grate product. GA.
