Gearbox Oil

[Lemon]

I used Swepco and was very pleased with it []

I am wondering if I should change it..? No specific problems but the car has done 90 odd k and I doubt ever had it changed.

I understand I need 2 litres (or a bit more to spill down my arm?).
and was wondering about this one
http://www.opieoils.co.uk/p-983-fuchs-titan-sintopoid-sae-75w-90-synthetic-gear-oil.aspx

..for no particular reason - its one of the oils recommended for the 944 S2 on the Opie web site.

Anyone used this, or suggest alternative?

Cheers
Ian

Definately worth changing the gearbox oil in my experience, I have mine done every year or two and it seems to make a worthwhile difference to the shift quality. Personally I can't say I found Swepco to be any better or worse than the others I've tried, but I know many others have had good results and supporting Bert at Berlyn (for the Swepco) or the guys at Opie (for everything else) is always a good move.

Ian, I changed it at about 90k miles, they whine a bit so good oil is important perhaps? On the same subject the CV Joints get a bit dry, you may consider repacking the grease in them George 944T 964

Did mine at about 120k, with synth stuff from a local Vauxhall dealer (chose the spec that matched the one in the workshop manual.) It cost about £8 for two litres (trade price.) Didn't make any difference! But gave me peace of mind that my toy was being looked after well (bless!) Oli.

After doing a bit of reading up on this and other forums, I chose to use Red Line 75w90 NS. It made a positive change to shift action, but didn't make any change to my transmission noise. Mine came from Fluke Motorsport whose service was excellent, even managing to arrange quick delivery when they were out rallying in Barbados. It is sold in quarts rather than litres though so you'll have to buy three bottles. Then again, using most peoples fill method (fill until you see it coming out rather than a little way below the fill hole) you would need more than two litres anyway.

Thanks all - sounds like a job worth doing. George - can you just release the gaiter to repack the CV joint, or is there more to it? zcacogp - do you know which Vx stuff exactly you used? I have a Vx trade club card but not a 944 workshop manual. I'm pretty sure it should be 75W90, but no more than that.

Ians, Listed on the invoice as S100000093165290 OIL2B TRANSM. OIL 4.03p each. Container was almost certainly a Castrol one, so I expect it's a Castrol product. Oli.

ORIGINAL: ians Thanks all - sounds like a job worth doing.

Definately. The service interval is 48k miles or four years (though I personally change mine every 2 years as fresh oil is far cheaper than a gearbox rebuild). Yikes, if a car really is on it's original oil [&o]
