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

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.

I agree with Straight 90 gear oil in the gearbox, but Hypoid / EP 90 is best for the axles.

Graham,

The synchro works better with Straight 90, no extreme pressure additives to stop the friction cones from doing what they ought to.....also does not effect the yellow metal, (bronze, brass).
