Yeah makes you want to honk your chips up....hate that smell of alloy and hypoid...

nothing wrong with the smell of hypoid in the morning lads! Though it does smell bad if on the garage floor I guess. 75w90 you reckon ? for a 1988 A80Quattro with a tiny 1.8i engine ?

In english it would be something like that:
"Usually use SAE-75W90 or API-GL5, synthetic or mineral, only synthetic has better properties - in winter cold it doesn't become so thick and in summer heat so thin, so it does it's work better."

so you reckon synthetic GL5 is best at 75w90? I have no idea, but need to identify the best oil at the cheapest price & audi can't help with either aim

That chap also mentioned russian made mineral transmission oil that costs 4 ls [between 5 and 6 punds] 5l, but I don't think something like that is aviable in UK

thanks chaps - so consensus is for 75w90 oil for a daily driver A80 quattro box - synthetic if possible ? does it need to be hypoid/GL-4/GL-5 etc ? I don't know much about gear oil!

any thoughts on what's suitable oil for the rear diff ? looks like it's been weeping slightly, but no idea how long for. so if I have to top up, might as well change it when I can afford to

The same oil as in gearbox, of course.

GL4 in the gearbox
GL5 in the rear diff.

thanks mikes2 - voice of reason as usual; am presuming from experience of filling your 88 quattro in your tagline. have seen advice somewhere else that GL-4 only for filling box, hence the question. easy to get hold of 75w90 GL-4 & GL-5 in UK ?
