I've recently completed a 12,000 service minus the fluid changes.
Fuel filter, air filter, spark plugs, lube shifter linkage (and replaced the fuel pump
that had given up after ONLY 127,000 miles). And now it's time to change the fluids.

My question is has anyone on this forum had any experience with the Lucas Synthetic
75/90w gear oil. I was thinking of using for the transmission and final drive.
The PO had used Mobil 1 for the first 120,000 miles. Lucas makes
great products that I've used in my other vehicles. Should I just stick with Mobil 1?

Is this an OIL THREAD? :confused:

Just yesterday I changed my gear box and FD with Lucas but not synthetic.
I have always been happy with their products also.



Features & Benefits
Lucas heavy duty gear oils are blended with an extra additive package, over and above the normal gear oil additives. With these products, you can expect longer oil life, lower oil temperatures, longer component life, fewer seal leaks and less noise. This is what gear oil was meant to be.

* Formulated with special climbing additives especially important in power dividers and hypoid gears
* Resists breakdown from contact with water
* Excellent for use in limited slip differentials, no special additive needed
* Blends with other gear oils, even synthetics

Just be mindful about the "special climbing additives". These may be tacky additive to increase adhersion in slower turning arrangements where lubricant is required in the top sections of gear sets, like in power dividers etc. I once tried a Kluber synthetic gear oil in a Jaguar XJS diff (circuit racing) and the oil "climbed" out through the breather.

When I read on a bottle of Lucas transmission additive that it "resurfaces bands", I laughed and shook my head. That told me I didn't need any Lucas products...... :rolleyes:
