Just bought a 1984 Supra with a Limited Slip Differential. The owners manual indicates that the gear oil should be API Service GL-5 lubricant for limited slip differentials. I went around to the local auto supply shops and none of the gear oil containers stated suitable for limited slip differentials including the synthetic and semi-synthetic. The fellows at the shop didn't know what the difference would be or if it was OK to use in the LSD. I bought the semi-synthetic API Service GL-5 lubricant . Is this OK for my differential? I checked some of the oil supplier websites (i.e. Castrol) and there didn't appear to be a specific oil for LSD. Just their regular gear oils said suitable for LSD.
