Golf SDI mk5 Veg?????

[ally406]

SDis are direct injection though, are they not? In which case there would be ring gumming issues if running single tank veg. I'd run it. But with water injection.

I agree, direct injection engines should be twin tanked or invariably the rings will gum at some point. I have read of people using water injection to successfully de-gum piston rings, personally I would go twin tank. All that said it really is easier just to buy a more veg friendly vehicle from the outset. Saxo/106 1.5D with Bosch pump is the ultimate cheap motoring as far as I can see, it works out marginally more expensive than walking.
