selling castrol syntrax synthetic 75-90 gear oil. have got nearly 40 litres of castrol syntrax oil spare. its in a barrel so can sell what you need rather than buying more than you need. this is genuine oil, any test welcome all retailers usually want a minium of 10 pounds per litre, will sell this for 7.

forgive my ignorance.. but what difference will this make? I heard that if your synchro is on its way out slowly then getting a thicker gearbox oil can slow down the effects?

 

where are you based as im due a gearbox and diff oil change? or is that the price including postage would need 5 litres.
