Hey guys! Thinking of dropping the oil out of the Mk1, 3000miles on it, doing the discs and gearbox oil so mite as well! What is best?? Think the dealer puts Mobil1 in her

I think JZM use a Castrol synthetic rather than Mobil 1...

I had Mobil 1 (post service @ Silverstone OPC) in my Mk1, and it used a fair bit of oil (had to top it up every 6 weeks or so). Since the last service (inc K400 kit) @ JZM, it's used virtually none (I haven't topped it up since September last year, and have driven it often on short-ish journeys to work and back). Spoke to Steve about it and he said it might be the change in oil.

Worth a phone call to Steve IMO

What do you reckon about the K400 - I'm thinking of it on mine. Did you get the mathey exhaust done as well? Whats the difference on insurance? - and noise level (for trackdays)?

Sorry about the Spanish inquisition!

Cheers

No worries Ajit - just PM'd you.

There was a suggestion from the PCGB site that a Silkolene oil might provide more start-up protection --- Pro-S 5w - 40, Ester synthetic oil for high performance engines --- approved by Porsche for the purpose.
