I love Amsoil and use their stuff whenever I can. However, they don't make a high mileage oil that helps with leaks and they have come off as snobby when I asked them if they ever were going to make one.
So, instead I use Royal Purple HMX which seems to work the best out of the three I've tried (M1 HM, Maxlife Full-Syn). However, I am still an Amsoil guy and would love to get it to work in my Jag if only the thing didn't leak so much whenever I use regular synthetics. I would just fix the problem, but its 10 hours of labor. So, do you guys think I could maybe try some Amsoil SS with some Liqui Moly Oil Saver, some Blue Devil, or something similar to make it emulate a HM oil?
