Hypoid SAE 80 gear oil

[arsenalofdoom1]

Aside from using the recommended Axle oil (Hypoid SAE 80) has anyone used fully synthetic or semi-synthetic and comment on the performance.

Any advice/feedback would me most appreciated.

Yep...a fully synthetic multigrade gear oil is OK.
I use Valvoline EP 75w90.

You could also use EP 75w80 which you can
get from Halfords.

To answer your other question about engine oil....

You can use part synthetic or fully synthetic.
I prefer 5w40 fully synthetic because the gears feel
a lot smoother. But 10w40 part synth., is what most
people use.....

**Apart from motorcycle oil, you can't use just any
synthetic oil but only synth oils which are rated for petrol and
diesel engines. But you do so at your own risk....**

In other words, read the label:

(Classes A1-A3 denote oils for petrol engines, and B1-B4
those for diesel engines)....
