Will never try any other oil in my vehicle only run amsoil

This oil I use in my trailblazer and impala

I use this in my 2012 Silverdo with the 5.3 V8 and it is great. I run it for a year and forget about it. Keeps the engine clean and cool.

Amazing oil, the best you can buy, noticed improvements in mpg

Great stuff!

I've been using this oil in my 2010 Taurus SHO since I purchased it in 2012. I've been on an annual oil change for most of that time, but recently changed to twice a year after I had the oil analyzed to see the impact the turbos had. While the oil was holding up, it was clear that a more frequent oil change was warranted. I've used this oil in my wife's car and the predecessor of the SHO. I also use this in my 1977 Corvette (albeit a different grade) -- so all my vehicles are protected.

Have been using amsoil since its start before being called amsoil. Had a ford explorer for 13yrs 278,000 miles. Still had factory compression specs when I sold her.

I have a 2007 Buick Terraza 3.9L V6. I have used Amsoil Signature Series 5w-30 since I bought it with 19000 miles. It now has 158000 miles on it. First thing I noticed when I switch to Amsoil was a smoother idle. Gas mileage increased 2 miles per gallon. Even with 158000 miles the gas mileage has stayed consistent at 19 in the city and 25 on the highway. I change my oil once a year with 12000 miles on the oil.

I use this in my brand new Subaru after 600 miles. Been happy as a pig in poop since. Been using Also in for 15 years in everything I own. Very satisfied.

Perfect in my cars all year round

I live in a cold climate, even at -36 there is no need to plug my vehicles block heater in.

The best.

2008cadillac dts I been useing it for 5 years in the car

I have been using Amsoil products since April 1991 and trust them completely to provide the best available protection for my motor vehicles. In my opinion, there is no substitute or equal to Amsoil's many years of R&D in synthetic lubricants and their resultant superior products.

I,ve been using Amsoil for many years and there's no better oil out there. Thanks Paul

I use all Amsoil products in all my SUV and cars Use the metal products on my firearms to prevent rust and smooth operation Amsoil is the best by far. And my family's trucks and cars

This is for a newer turbocharged volvo, oil always looks good when it comes out and the engine is nice and clean inside as well.

Have been using this oil since 2005 in my truck. 2005 silverado 5.3L tuned and full bolt ons. I had used it prior for 3 years in an older truck I had. Very confident with Amsoil that I've been changing the oil in the silverado once a year for the past 11 years. I also have a 2014 and Amsoil is used in it as well since the first oil change was due. Back to the 2005 truck. Reason I told you its tuned... many people know how a tune gets your engine a "little" less life. Well, I have had to change out the valve cover gaskets twice within the 11 years I've owned it and as far as valves and heads. They're like brand new. Once a year change intervals. Truck has 140k+ miles. Amsoil has kept it running smooth since day one. Can't beat that!

I use it in 2008 Taurus and a 2015 Ford Explorer. I've used it in the Taurus since 3000 miles and it now has 115,000 miles on it and have had no engine issues and still get 22 - 25 mpg. I bought the Explorer new and have used it since the first oil change and it now has 41000 miles on it. Love the oil ! I would recommend it to anyone looking for a high quality Synthetic motor oil.

Best oil for cold weather start ups. It increased my fuel economy from 27 average to 29
