Well, have changed the plugs this morning for NGK single electrodes and TBH there's no noticeable difference... I think the flat acceleration has improved slightly but hard to tell :-/ :-/ I did find that 3 of the plugs were a little loose (could have undone them by hand with just the extension bars ) but nothing untoward really. A little oil in a 2 of the plug wells but I think it's old (from before the Cam Gaskets were replaced) as it was darker than the oil I drained and fairly minimal... I'll be keeping an eye though!

Anyway, I thought I'd post some pics of the plugs I removed...





These have done about 24k, 18k on LPG. Look good to me TBH

So, my initial conclusions are: Use GM plugs for LPG converted cars too as the seem perfectly man enough for it! I'll probably swap out the NGK's sooner rather than later for a set of genuine ones

They look fine.

Gm plugs are pretty good, certainly not worth fitting more expensive variants

My thoughts exactly, apart from the obvious oil contamination on the fist 2 ... Only really went with NGK single electrodes as a trial for us LPGers... I doubt I'll run them for as long TBH as the GM ones are better

Would have thought that any oil left from doing your cam cover gaskets would have burnt away, perhaps they are leaking again :-?

That was my first thought but I'm not losing any oil between changes... And it was much darker than the oil which came out yesterday! Stays right on the mark :-/ :-/

I'll keep an eye on it and see what happens
