Great productBy JOSHUA, a Verified Buyer from North Carolina on May 16, 2025I currently use this in a 2015 Toyota rav 4 with 122,000 miles. Been using the high mileage oil ever since the vehicle had 75,000 miles. The vehicle sees a lot of short trips. The vehicle doesn't "use" oil(not adding an extra oil) between oil changes. In one year we usually travel around 10-12,000 milesBottom LineYes, I would recommend this to a friend.Was this review helpful?

Always AmsoilBy MATT, a Verified Buyer from Bristol, CT USA on May 01, 2025I have been using Amsoil products for about 20 years or more. I used it in my Harleys and all my cars. I remember a ball bearing test report that came out a long time ago that made me consider using AMSOIL and I have been using it ever since. I use it in my 2007 350zx as well as my 2024 Acura Integra Type S. I use signature series synthetic, good for 25000 miles, and I change it every 5k miles, I actually changed my oil the first time at 1500 miles, then again at 5k, and now I will do it every 5k going forward to make it easy to remember, 5, 10, 15, 20, 25, etc.. It costs a little more, but instill confidence and makes me feel good, so I don't much care about the added expense, I change the oil myself, so I save a little money there. IMO, better than Mobil 1, Penzoil or just about any other brand out now.Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Good product!By ROBERT, a Verified Buyer from Nevada on April 28, 2025Met my representative Ron at a local outdoor show. I told him that I had been looking to use Amsoil products. He informed me of the products that would fit my application. Helped me establish my account. I placed my first order. Web site was easy to use. Order arrived in a few days, complete and accurate. Last week, I changed my oil. The nice touch was the included thick vinyl gloves and paper funnel.Bottom LineYes, I would recommend this to a friend.Was this review helpful?
