been meaning to change the oil in my K bike gearbox and bev for a while suppose I should check the oil in my toymota diffs aswell seeing as you say they need gl5 aswell (not hilux but apparently it shares the same diff internals) seem to remember using up all my odd ep80/90 non gl5 oil in the last one
I don't have a Toyota............. or a Landrover Guess the rest of it will have to sit on the shelf with all the other oils, waiting for another service to come round
