Was having a discussion with a mate about my recent transmission oil change on my 90 series.
Manual says to put either GL4 or GL5, and since I heard GL4 was more recommended for manual gearbox, I put in that. But the mate says I was stupid because GL5 was better, if the manual says I could had also use it without a problem.
What would you use?
