Not what a lot of other users have done. I've done 2k miles now on 100% veg. Better to mix it however which I will be doing a lot more with it getting colder.

I hate to say it, but if it is a stripped plug thread, only option is head off and helicoil it... I absolutely hate bodges on any of my cars like this one, but given that the work involved just to fix the thread is so huge, I'd leave it alone and hope it isn't leaking gases. Pretend that it's meant to be like that! I've never had to helicoil a plug thread. They are very fine and I'm not sure if a helicoil kit even exists for such a fine thread. People (who don't already know), plugs only need to be a bit tighter than finger tight! @axe just had a crazy idea to check if it is leaking... when the engine is stone cold, get someone to sit in the driver's seat and start the engine, while you're drizzling washing up detergent water over the cap. Bubbles mean a leak... You might get a temporary misfire if the water shorts out the HT, but as soon as it's warmed up again it'll dry and be fine If it is leaking, it's simply a question of how long can you handle it- a bit like a leaky head gasket. No fun WOT driving....
