Game ChangerBy MARIANO, a Verified Buyer from Illinois on October 23, 2026I drive a Jeep Renegade which is notorious for oil consumption. After going through different store bought oil brands and on average, it burning up to almost a quart of oil on every 4000 mile interval oil change, I've decided to switch to Amsoil to see how it performs. I've gone through two cycles of of oil changes with Amsoil and haven't had any issues with oil consumption at 4000 mile oil change interval's. Amsoil has been vastly superior to the store bought oil brands.Bottom LineYes, I would recommend this to a friend.Was this review helpful?

Simply the Best Synthetic Lubricants on the MarketBy STEVE, a Verified Buyer from Arizona on October 23, 2026This oil, like all the other AMSOIL lubricants, are far superior to any others on the market. I’ve been using them exclusively in my garden equipment, motorcycles, 4x4’s and cars for over 25 years and have never had a lubricant issue or problem. I get better mileage and cooler running performance than before and the customer service is always great. I recently bought a 1963 Thunderbird and they provided me with a complete list of lubricants and filters, right down to the correct fluid for the convertible hydraulic cylinders. Great products, great service; I’ll be a customer for life.Bottom LineYes, I would recommend this to a friend.Was this review helpful?
