I decided to us this oil in a Civic turbo that my daughter drives and doesn't see regular inspection. So far I have gotten excellent service.

Best oil

I absolutely love Amsoil. Great customer service and speedy shipping. I switched all my vehicles over to Amsoil.

I have used amsoil products for years. I have absolute and total trust in the quality and durability of all the products. Like the old saying goes " pay me now or pay me later ". Use the very best to take care of any engine and the engine will take care of you. Thank you Amsoil.

Thank you for your product and your prompt delivery service I've been using Amsoil for 40 years I will never use anything else I won stock car Championships with Amsoil and I use it in all my vehicles I'm glad I found this website thank you George

Moved to the XL 10w-40 Synthetic oil on my 02 truck, runs great! starts even better than great! Thanks Amsoil !

I use all Amsoil products in my personal cars, pickup trucks and race car. Have nothing but good things to say about it. Would not use anything else in my vehicles.

Great product for my 2008 LS460. Just reach 150,000 miles without any oil consumption issues!!

Good Product, Fast delivery.... using it for 15 years now.....

Have been using this oil in my Subaru since I purchased the vehicle. Vehicle performance continues to be excellent, runs cooler when in Arizona, mileage has stayed consisted. Car starts easily in the cold.

Have used for over 20 years now in all my vehicles. Have had one truck go over 300K miles before it was broadsided and totaled out by insurance. Was still running strong. Have another truck and car with over 200K miles each. Have two more cars with over 150K each. I love this product!

I started using Amsoil in my 1966 muscle car Z Rod. Liked it so much I began using Amsoil products in all my vehicles and now jet skis. Amsoil ships straight to my house and I can do it when I need to service our cars. Love the service, oils and filters

Great product all that needs to be said

i have been using amsoil since 1985,initionally in my m/c. 30w was all i could use, 25000 miles later the cam chain had grown, at the time this was an engine take down. my ex kawasaki mechanic called me and said come over and bring ur camera. this puzzled me, i thought that he was going to show me some burnt (bent) valves or pistons, no no he could not believe the bearing surfaces with barely any wear. i have been sold ever since. amsoil is the best.

... My cars and my customers are spoiled with this great product !

Have been using this product for years and I am very pleased with the outcome.
