Synthetic is better, more longevity and better thermal stability.

weekenny where are you.it was i post i read regarding synthetic oil in rear diff causing noise in the rear diff and being resolved by changing to a mineral based oil?

 

[spacecadet]

would an oil with an ep rating not be more beneficial,giving insurance to the gearbox and diff?

The EP oils are mineral, and the syntheitcs are represented by the GL5 rating, in terms of load bearing they are both capable.

You will be fine with either, but synthetics offer more protection.
