teasdam Posted March 1, 2004 Share Posted March 1, 2004 My Chilton says to use GL-5 in open differentials, and GLS in limited slip diffs...how do I know which diff I have? The car is a 1990 Loyale, 3sp AT, 4WD Also, it only recommended 85W for areas with colder weather. Does this sound about right? Quote Link to comment Share on other sites More sharing options...
calebz Posted March 1, 2004 Share Posted March 1, 2004 You don't have an LSD, unless someone put it in there after the car came from the car lot. If you had an LSD, there would be a tag on the diff that said LSD. But they didn't come on automatic cars Quote Link to comment Share on other sites More sharing options...
