Running Semi-synthetic Oil In Gearbox..

[Links]

Getting my gearbox bearing replaced this week and mechanic is using semi-synthetic pennzoil gearbox oil in it..

I have run this for 5,000kms since the last service (and before it broke).. what was in there before I have no idea..

What I want to know - is it ok to run semi-synthetic?

Would it be better to get something like redline shockproof lightweight (not sure but guessing it's full synth)..

I'm pretty sure it'll be fine - but wondering what peoples thoughts are..

Cheers

i'd go the redline (yes, it's fully synth) personally, but that's just because i have a thing for redline gearbox oil...

there is probably no harm in using the semi-synthetic, the redline is probably better for your gearbox though.

Cheers Merlin..

Going to run some pennzoil + a tube of nulon to hopefully make it a bit nicer to smooth..

Have to wait and see..

Just Jap lost the order for my clutch kit.. so have to wait till monday now..

Nulon gets pretty bad review in BITOG, you may want to reconsider using it.

Huh - how the hell does that work - that was 4 comments about nothing on that link..

I'll take peoples word on SAU before I decide not to use it.. From what I can tell everyone recommends it and haven't had any issues..

And I think that could be referring to a one off store selling Nulon E10 for $0.99..

Oops sorry about that link. I did a search and not much is say about this Nulon stuffs.. only PTFE, but a local Tribology Molakule explain more of the ill effect on PTFE on engine.
