    Which is the best choice to my 1g 90 GSX transsmision: mix of Red Line MTL and MT90, MT85 ONLY or MT90 only ?
    I live in Sweden so in winter reaches -20 degrees.

    I use a mix of the MTL and MT90 in my 2G. Transmissions are pretty much the same.

    I use the redline synthetic mt90 and it works great! Always smooth shifts and gear changes.

    I use mt90 with about 1/2 qt of lightweight shockproof in mine. Works great year round, we get temp swings from -20 to +105f.

    Diaqueen is great stuff too, but it's expensive as heeeeell.

    3 quarts of mt90 in the transmission, to be exact i think you need 2 and a half quarts for the transmission, but 3 bottles will cover it, 1 quart of lightweight shockproof for the rear diff, and 1 quart for transfer case, that is what I'm running it makes shifting feel a lot better vs the average gl5 that parts stores typically sell.
