Club 80-90 Forums

I just spent 4 weeks running my 1967 1200 bug on Bio Ethanol...
(purchased from Morissons)
After some serious 'up jetting' of the stock carb, I managed to get the bug running right...however MPG was down to around 17-20mpg....!!!!
(Running a 170 main jet and .80 pump jet)

Bio Ethanol is around 35% less volatile than petrol, hence you need to add 35% more to you fuel/air mixture....

Im back to petrol now because it was costing me a small fortune, although I did enjoy the sweet smelling exhaust and the very Cool Running engine temps....!!!

Hi, it was costing me 90p per ltr.....and mpg was down to around 17mpg!!!

My bug retruns 30-35mpg when running on petrol.....

I was wondering about this as E85 is being seen at more stations...
and was about 45 cents L (35p)
Ethanol has a higher knock rating though, so can use higher CR and more advance on the timing..
My "DJ'd" DG, might work a little better...
