I like the fact that I change my oil twice a year with good protection and is priced as much or less than conventional oil

I have used this brand on and off for 13+ years in my 4Runner, alternating between it and the Signature Line. I finally settled on the XL and I prefer to change my oil twice a year and this model works well with my schedule and mileage.

Been using Amsoil on my motorcycle, car, truck and lawn tractor for years. Best oil out there IMO

Put Amsoil in all vehicles. Getting great gas mileage and runs smooth ... ?????????

I use Amsoil in everything I own. Even my lawn care equipment and generators. I've never had a oiling problem since I started using it in 1986.

its great products

I use this for both the Chevrolet Crate engine in my Chevelle and my Camaro SS LS3. Best protection money can buy. Wouldn't think of changing.

I bought this oil for my wifes LR4 . this oil has been amazing engine is queiter & gets better milage. No more trips to the dealer for oil changes for me on this one . Changing all my vehicals, TJ unlimited & my pro tour Camaro over to Amsoil.

Great oil and will be buying again

Quick ship,easy web site, good product. What is left to say?

Great product increase I fuel economy and engine runs quite and cooler no regrets switching to amsoil.

I have been using Amsoil products for over twenty five years in all my vehicles and have never had a problem related to poor lubrication.I have never purchased a new car in my life and routinely run up over 200,000 miles on whatever I'm driving.I think that say's it all. Frank

I switched all my cars and bike 2 yrs ago very happy with the performance

I use this weight in my 2009 Hyundai Genesis, and it has over 107,000 miles on it.

I use this oil on my work trucks (2) 2016 Dodge Ram V8. Uses different weight but XL kind.

I've been using AmsOil for my Subaru Impreza WRX since 2005 and when our family truck, the 2008 Toyota Sequoia finally used up the extended maintenance service contract in 2013, I started performing the oil changes myself with AmsOil XL products. Since my WRX has been on this synthetic oil for many years, I figured having both vehicles on the same oil would be the best thing I could do for them to keep them performing at their best. It's been the best feeling to be able to treat the cars with these proven and high quality products, specially Oil and Oil Filters on both my cars. I don't feel bad if I push the cars a bit or if I miss the change interval by a few thousand miles, although that is rare, but I have a sense of trust that it will continue to protect the engine even if I slip a bit. glad to be using these products.

I like to drive my vehicles 200k to 300k miles before replacing. Amsoil has always gone the distance for me.

I use the oil in my Subaru and my gas mileage has improved. Once a year oil changes are nice.

Use this in my old Chevy 454 powered motorhome. This motor really works hard and gets Hot. Oil pressure stays up on hottest days and no leaks or oil burning. It's the best protection for my motor that I can find.

I' started using Amsoil 8 years ago because of issues I had with Mobil 1 figured I'd try Amsoil and was impressed by the mileage increase and price, plus the longer service intervals.
