gazzaw Posted January 3, 2009 Share Posted January 3, 2009 It has probably been answered a hundred times before and there are threads on here somewhere but can't seem to find them. With reference to the G503 lube chart etc. What are (modern) british equivalent types of oil and lubricants that will be compatible with the jeep -e.g. engine oils, gear box, transfer case and axle oils etc I don't want to relube and change oils etc to find that I have used wrong type that will rot or melt seals etc. Jeep previously from California and never been serviced here until now Thanks Gary Quote Link to comment Share on other sites More sharing options...
Degsy Posted January 3, 2009 Share Posted January 3, 2009 A straight 30 grade for the engine and a straight 90 (NOT EP) for the transmission and axles. I have always used Morris's versions of these specs in both Jeep and Jimmy. Quote Link to comment Share on other sites More sharing options...

I have always used Morris's versions of these specs in both Jeep and Jimmy. I agree with Straight 90 gear oil in the gearbox, but Hypoid / EP 90 is best for the axles.

Tony B Posted June 17, 2012 Share Posted June 17, 2012 Richard is EP90 compatable with Dodge axles as well? Quote Link to comment Share on other sites More sharing options...

Degsy Posted June 18, 2012 Share Posted June 18, 2012 Richard is EP90 compatable with Dodge axles as well? No, according to the TM it takes straight 90 in the gearbox,transfer box and axles. Quote Link to comment Share on other sites More sharing options...

spanter Posted June 19, 2012 Share Posted June 19, 2012 Hello after having the rear diff rebuilt for my WC54 by Rex Ward he explained that ep90 is what he recommends for dodge axles as no bronze in the diff and the crown wheel and pinion will break the oil film of an ag90, and looking at my worn out pinion I'm going with his advice as I always used ag90. Definitely use ag90 in the gearbox and transfer case though as sure there is bronze in there. Steve. Quote Link to comment Share on other sites More sharing options...
CharlieH Posted April 2, 2014 Share Posted April 2, 2014 Just quickie, what are the quantities of 90w for the gearbox and transfer? What's the best way to fill them up? Quote Link to comment Share on other sites More sharing options...
