924's don't have tarantulas (tarantulas are 9 spoke, 924 is 8), call them "standard alloys" instead?

924 and turbo coolant is 7 litres from dry, about 5.6 litres on a change

924 oil is 5.5 litres from dry and 5 litres on a change (both including filter).

924 Turbo oil is 6 litres from dry and 5.5 litres on a change (both including filter).

Great idea, will dig out my 924S drivers manual tonight/tomorrow and fill in what I can.

Once complete I will probably create it into a Technical Article if that is ok?

Yes, sorry I forgot to say in my first post that was the intention!

Good help so far, will update post 1 when I get a chance

Why would you call a 9 spoke wheel after an 8 legged spider?

I didn't

blame it on the VW crowd but some spiders do have nine legs anyway.
