Re: '90 200Q Transaxel lubricant

Hi Gordon;

    The Bentley spec says GL4 SAE 80 (mineral) or G 50 75W90 synthetic. Your
tranny will contain the synthetic oil. I would top it up with the OEM G 50
oil since that is what is in there already. Why take chances with the tranny
for a couple of bucks saving in lube?
