I just brought my 1984 Saab 900 into the local SpeeDee for a quick oil change and decided to have them change the gearbox oil while they were at it. I asked the technician what he used and he said "80/90 weight oil." I said the owner's manual says to use 10W-30, which is what I have been using. He checked his reference book, which said "80 weight oil can be substituted for 10W-30" in the 1984 Saab 900. Hmmm. Does this sound right? I'd hate to muck up the gearbox since it's been working great, smooth shifting and no problems. Thanks, -jw 1984 900S 128K mi.
