Hi Ian

I've got a V1 Muggy 186 and always run it on ordinary supermarket 95 RON unleaded and a quality Semi Synth oil . 5 years on and no problems whatsoever.(and I rag it!!)

There is a consensus that the additives in Superunleaded are causing problems (petrol/oil breakdown?)

Hope all is well with you

Shan't be over next week

No, but avoid Morrison's cheap fuel, their fuel has a high ethanol content according to reliable sources on here. Not good for our motors.

My tuned motors are set up on Asda fuel, which seems good. I have had more than one strange incident with BP high octane.

If it's an early Muggy I would get the head checked for comp ratio. Some were supplied with far too high compression. Depending on dealer.

That's interesting, our Shell garage has recently been taken over by BP. I've used Shell V-Power for years with no problems. Since using basic BP unleaded I've been plagued on all 3 of my Lambrettas (3 different makes of carb!) with the chug-chug-chugging syndrome when starting hot. Something has changed and I'm jumping to a bit of a conclusion here but it could be the petrol.
