Amsoil Signature Series is great engine oil. I have used it for over twenty years in my cars and trucks, without an engine problem. I replace it every 15,000 miles and my engines run as good as new and are as clean as new after well over a hundred thousand miles.
I have been using Amsoil products for about 13 years and found them to be superior to regular ones. The oil is awesome and I give it credit for extending my oil changes longer and saving $$$ on that. The gas additives also improve MPG in all my vehicles too, 3 cars and 2 motorcycles. Regular oil analysis confirms the oil is doing its job without damage to my engines. I believe Amsoil is far better than any other synthetic oil on the market and way better than conventional oils.
Was a "FULL SYNTHETIC" for a long time, maaan was I wrong. I drive a v8 and I've switched everything to AMSOIL, what sold me was using this oil on my wife's Camry, 3 days after changing the oil using Amsoil, she asked what I did to it. I asked why and she said : it runs soo smooth, I was sold switched everything out immediately motor ,trans and differential on both 2016 Camry and 06 Tundra 05-w30. Thank you Amsoil "the best"
Been an amsoil customer for years. From quality oil to customer service Absolutely Top Notch!!!
I use signature series amsoil in everything I own. Flawless Victory
I’ve been using this oil for over a decade in an ‘06 Tundra, ‘09 CRV, and ‘10 Infiniti G37. These vehicles continue to perform as new and do not use any oil. I’m convinced this product is superior to all others.
I have used Amsoil Oil for a Number of Years. In my 2003 SVT Focus with 346,500 Miles on it and a 2011 Saab 9 3 . Both Cars are still running good with no Engine Teardowns. I believe in Amsoil Oil Products. You would have to tear down Engines to see what my using Amsoil Oil has done.
Bottom Line
Yes, I would recommend this to a friend.
