This product was brought up, and recommended as I read up about a particular vehicle that I purchased as a every day driver that has some possible catastrophic piston issues due to pre ignition, as I understood it to be, and I put about 400+ miles on a week on it. I change it, and the filter every 5k miles and hope for the best, so far everything seems fine.
I have been using Amsoil for years and I am very pleased with the results. I just replaced the timing chain on my Mazda3 with 126,000 miles on it. When I removed it, it looked just the same as the new one I was replacing it with. No wear on the tensioner guides either. I'm sold on Amsoil.

Stoked to finally try out Amsoil in our 2015 Subaru Outback. The shipping was super fast and packaged well. The ol sube has over 200k on her so I thought I’d better start using a super premium oil like Amsoil to stretch that life out of her. Really happy so far…oil consumption isn’t a problem after putting 3k on this oil change so far. Royal purple was the previous oil used for the first 200k and at this point I would have already added at least half a quart. So like I stated…so far so good.👍
After running this oil in our SUV it helped to run quieter and reduced oil consumption to none. I would recommend this oil to anyone with a higher mileage engine. Just keep up on your oil changes and Ams Oil can really make a difference in your engine.
Bottom Line
Yes, I would recommend this to a friend.

Low on power

Been using this on my 327000 97yukon 2door and truly think Amsoil is the only reason why my suv is still running as strong with no engine issues. I drive my truck seven hours to west texas towing a 171 jayco once I get there I idle my truck while working for 13-14 hours a day in heat, cold, rain, dust storms, and still drive it back to south Texas after my fourteen day hitch. I send my oil samples through the company I work for and have never got back a bad or concerning sample even if go over my mileage intervals. I would never leave amsoil and take a chance with any other oil
Bottom Line
Yes, I would recommend this to a friend.

I am stuck on Amsoil. The best, longest-lasting lubricant for my internal combustion engines. I love cars. I enjoy well-running machines. THIS is the only oil I will use.
Bottom Line
Yes, I would recommend this to a friend.

Good oil. It doing a good job on cleaning my engine. To me I am getting better gas mileage
I've been using Amsoil in my car and Harley for a couple of years now with wonderful results, so I decided to switch to the high mileage Amsoil for my car. It's performing exactly like I'd expect anything from Amsoil to do. I'm an Amsoil customer for life.
Amsoil was extremely professional and quick with their updates on my order. I got some 5W30 and a filter and love how my 1998 K2500 has been performing.
Glad to see Amsoil introduce this product. Started using in my 2 high mileage Chevy S10 pickups last fall when it was introduced. Too soon to tell anything but I'm a long time Amsoil user of their products.
