how to improve Aircooled mpg

[HarryMann]

Yes, Maybe its running very near the detonation threshold or you have it right up against the adv. curve, being std. and low comp shouldn't need it, as high octane releases no more energy. Any local cyl overheating (aircooleds very prone of course) would also make it profitable to keep the anti-detonation properties of the fuel up.

e.g the exhaust seats can run v.hot

both engines are running stock ignition settings , even on a roads and around town the bigger engine is a vast improvement on fuel consumption over the stock cu motor due to not needing to use all the gears when pulling away

I've just had my '81 converted to LPG (Gasure), cost about £1200 and so far would recommend it. I reckon I saved about £30 over normal petrol price between London and Glasgow and as I'm about (hoping!!) to do 3-4000 miles around Europe soon it makes sense for me. Was told by Steve (Gasure) that it also reduces road tax but not looked into that fully yet as just sent off V5. If so that also could be a big saving as we're paying £230 or whatever a year..

Just google it buddy, all the info is there, especially on the money supermarket site, do it right and get £10 off
