Keeps my older van and car running like a charm. Lasts for a year just make sure to check oil levels.

Love the quality and ability to only have to change my oil once a year or so.

Use it in my 1987 Buick Grand National 740hp 3.8l V6 I also recommend it to many of my customer that have hi performance vehicles.

I put this in my '09 Ford Edge and I am really excited for it. This is the best oil I have put in this car, so definitely looking forward to long term use with it.

Love the Amsoil products. 2 of my vehicles are going on 300,000 miles and run great. I use the 5w - 20 in my 05 accord. I am sure that my vehicles run smoother with Amsoil.

I used Amsoil 20 plus years ago in my 1997 tahoe, then switched back to conventional oil. I know oil technology has made great strides. However I had this nagging feeling to using Asmoil again, so I did in the same 1997 tahoe I still have today us a 2019 GMC Duramax. I plan on having my 5.7 in the tahoe stroked out to 383 ci. and I plan on using Amsoil products in the motor, plus I plan on having there oil bypass system added to my diesel. Good stuff.

I bought this oil on recommendation from my brother in law. I got some for my suv and my pickup truck. Everything’s been great so far. Quality oil. Ordering process was a breeze and shipment came promptly. I won’t use another oil going forward. Just wish I had some Amsoil swag for my garage!

The XL is a valued alternative to the more expensive Signature Series, as I change my oil every 6 months, regardless of miles. It still has plenty of additives to do the job, and keep my engines running smoothly.

18 3.5 eco Drove 120000 km oil life still at 33 percent saying it has 4500 km till another oil change is needed and the viscosity left in this oil after 12000 km is insane that means 100 percent to 0 percent oil life is 17000 km amazing product

I run this 10W30 in a conventional small block Chevy producing around 500 hp. It’s my regular driver in a 10. The oil gets abused with the heat here and the extremely dusty environment. Amsoil handles the demands of this environment without any problems. Engine are always clean as a whistle whenever I open them up. Really great products across the entire line of motor oil.

Only oil I'll use in my vehicles.

Been using this product for over 10 years in my Honda Fit. Absolutely no problems.

very happy with my amsoil products, i did a full service on my vehicle with all amsoil, the car noticeable runs smoother, and quitter and has improved my fuel mileage by 2mpg. this stuff really works!
