Guys don`t beat me up to bad... I`ve tried to find some user feedback on Amsoil. It appears that most members here prefer PU or M1. In all seriousness can you say why? I used to use Penn, QS, back in the old days with Dino. I have used M1 in past vehicles tho. In my Work vehicles I used Amsoil when I needed the longer OCI`s., and currently use Valvoline, Castrol GTX, and Supertech at the proper intervals with the other cars... so I find myself questioning which oil to use. trying not to over think this but it does get confusing with all the new synths, blends, and so called synths... I currently need a good 0w20 in the Toyota. I have read many threads here on the Toyota oil and agree with your findings. I understand it is their proprietary blend, but pricing @ 93$ a case before tax is a little nuts and not local. I could use a very good similar or equivalent oil that is more readily avail and easy to obtain. However, I will be doing 5K oci`s bc we Tow with the FJ in season. Thanks for reading!
