I have used AMSOIL products in my cars for almost 20 years and have never had an oil related repair. I will always depend on the most dependable lubricant for all my vehicles.

All my important engines will always drink Amsoil. Excellent products!

Best thing to ever put in my engine

Great oil only oil I use.

Great Product that is delivered within days of my order, no fails in 10 years....

You can definitely tell the difference between this oil and a regular oil. I would definitely use this oil in everything that I own.

Good Products!!!!

This is an amazing oil for high performance engines!

TTUTO bene grazie good oil

I bought my GMC pickup in 91 and immediately changed it to Amsoil premium. For years I changed the oil filter at 10,000 miles and the oil at 20,000 miles. Now I use Amsoil XL and change the oil yearly. The truck has 275,000 miles on it and the engine has never been torn down, oil consumption is minor. I also use Amsoil in my wife's cadillac DTS, 3 lawn mowers and log splitter. Their products are the best.

Bought used avalon for granddaughter. Did some engine work and notice some slug. Run amsoil flush and added synthetic back in the car. Always a good move to clean up engine.

Love their product, we use Amsoil in all our vehicles( Kia Soul turbo and 2017ss camaro) Highly recommended

With the cost of the Signature Series motor oil getting progressively more expensive every 4 months, the XL line is a better alternative. I used to use the Signature Series all the time but it has gotten out of hand with pricing.

Since the Signature Series oil has gotten progressive more expensive, the XL line is a more reasonable alternative that won’t break the bank.

I have found XL to be a great value alternative to Signature Series, if you change your oil every 6 months, or 5-7k miles. I am satisfied with the performance and protection for my maintenance schedules.

This is the only oil I have used in my pickup, since I bought it new in 2014. What a difference starting on a cold Wisconsin winter morning.

I have used the 0-20 xl Amsoil which is a good product, but switching to the boosted 0-20 Amsoil, has increased our fuel mileage 2 miles per gallon. I have switched back to the 0-20 xl and have seen the mileage go down 2 miles per gallon, so I can say the boosted 0-20 Amsoil is a very good product.

I use this in a F-150 Ford pickup and have since I bought it 7 years ago. I average 12,000 or less miles annually with this truck and it runs like a new engine. When I pull heavy loads it runs smoothly and quietly.

This oil keeps my wife's 4 Runner running like a new vehicle every year. Great protection and 12,000 miles between oil changes. With three other vehicles its wonderful to do only one oil change per year.

The convenience to be member of the Amsoil VIP, the great quality of the product have helped protect my SUV for at least the last 100k miles from the 300k it has. I will keep getting this product to keep protecting the engine and other components of my truck with Amsoil!
