    Mobile Delvac/Synchromesh VS. Amsoil MTG 75/90 for G56

    Zeng, Viscosity is all about the same according to their SDS/MSDS. There all right about 86/14-15 Cst. And I know the MTG was airated severely, as when i came out there where tons of bubbles/foam in it through I hadn't moved the vehicle in at least 3 or 4 days. I had to wipe the foam off the...

    Wanted to update this thread. O2SE...You where right! Part of the problem was overfill beyond the acceptable extra, see below. Drained the Amsoil MTG and found out that it was overfilled by about a quart to quart & a half OVER my overfill. So my 7.5 quarts was actually 8.5 to 9 quarts and the...

    Mobile Delvac/Synchromesh VS. Amsoil MTG 75/90 for G56

    Well just a follow up, since nobody could provide any good information on additive packages effects I ended up going with Redline Synthetic 75W-90 and it seems to be working but it is a compromise of better shifting performance for less gear protection.

    Comparison of 5 oils for Dodge Diesel manual trans

    Does someone have a VOA on the Torco RTF? One that might include sulfur PPM content? Since it is GL5/GL6 with "EP Additives" according to it's tech dates sheet, I'm wondering how much Sulfur it has in it?

    Mobile Delvac/Synchromesh VS. Amsoil MTG 75/90 for G56

    Seems kind of ghost townish here now that I've provided all the information, no answers to the question again. Guess nobody on here knows nothing, must be magic fairy dust like I speculated earlier? How about anyone have a VOC analysis on the Mobil delvac 1 synthetic transmission fluid 40?
