Thanks for the reply re my 968cs. I assume its best to run it on super unleaded ?????

They do run better on super but also now with E10 unleaded there is some debate that these older cars may have to be run on the E5 super. Less chance of fuel hose degradation.ted walker said:
How true that is is still in debate as Porsche don't seem to have definitive data so are erring on the side of caution.

Yup, I've been sticking to E5. Porsches own tables show the 968 as incompatible. Think only the Boxter onwards(?) Always have in the car though a bottle of Millers E10 additive mix should I get caught out on a long trip and no E5 anywhere around. I suspect though that if you could (at great cost) rip out and replace all fuel lines with later hoses/pipes then you'd be E10 ok, but cant vouch for any changes needed (if any) for the fuel tank.

If you search far enough back on here you will find that Porsche GB stated that 968's are not compatible with E10 without major replacement of all "rubber" lined items between the fuel tank and the injectors. As a 20+ year owner of 968's, long time and continuing member of the 968UK forum and until recently (and latest version) 15 year PCGB member I have followed the discussions about E10 with considerable interest.
My personal experience - I bought my first 968 in November 1998, the tip coupe, and ran it for quite a few years on 95RON without problems - until the introduction of E10. I switched before then (when the car changed from daily driver to weekend toy) to 99RON (Tesco Moventum), noticed that the car was happier, performance was better, suspect MPG increased a little. Stayed with 99 for the rest of my coupe ownership and my 8+ years tip cab ownership.
Major problem is that certain flexible components of the 968 fuel system are NLA - which is why, when corrosion problems arose with my cab (MY92), I had to convert the fuel lines to MY93< at considerable cost. The cost far outweighed many years of using E5 instead of E10, so unless corrosion etc raises its ugly head, I'd recommend sticking to E5 rather than messing with the fuel system.
One word of warning IF you take the car into Europe. I was in Northern Spain in the cab, pulled up to a 99RON fuel pump but noticed an E10 sticker on it - so asked first. E10 was confirmed, so I moved on to a different petrol station - Repsol - where I was told that their 99RON is better than E5 as at that time (don't know if it's still the same, this was about 6 years ago) Repsol do not add ethanol to their fuels.
968's are seldom daily drivers, so the additional cost of E5 for the mileage you do in the car is un-noticable - so stick to E5!!

As it's a Sport in GR, I think for originality standard would be silver rather than body coloured, AFAIK that was a CS standard on most of the (limited number) of CS colours. Having owned 3 GR FE Porsches including for 12 1/2 years a 968 tip coupe, my personal opinion irrespective would be silver.

Ran around with the original/genuine silver Cup 2's for a couple of years on my GR S but eventually thought they distracted from the rest of the car (silver wheels being a brighter contrast and 'standing out' more than the car itself). Wanted to match the same contrast as the GR and went with anthracite in the end which actually worked out great - just looks a tad more purposeful without being brighter than the rest of the car. As always though horses for courses and all that..
