"Pinging" Colorado

Will

Engine is running at normal temp, I agree about the engine management.
Recommended fuel is min 91 oct unleaded, no Im not using E10, not keen on it. Next fill I might try premium.
I could be letting the rev's get a little low under load, as this is when it seems to happen.
Thanks for your ideas/comments.

One of the kindest things you can do for a petrol engine designed to run on UL is to use Premium UL. Because of the absence of certain additives (haven't got a clue what they are called) it will burn cleaner, keep your fuel system a lot cleaner and in my experience the engine oil stays heaps cleaner between changes (change every 5,000 km). Some people also claim to get improved fuel economy and performance. that hasn't been my experience. I use a couple of super strong 'rare earth' magnets wrapped around the fuel line from the tank. Sure makes me feel like I use a lot less fuel !!

Barry, sorry this is late, been away at work and got back last night.

Pinging starts at around 1800-2000 revs, and yes if I lift my foot off it does go away.

Yea, I was thinking that as well. I was taking it easy, trying to see what sort of economy I could acheive, maybe I need to go a bit harder.

Tim this is not the way to solve the problem. It may help in the short term to disguise the problem but the extra load on bearings will not change.

Need to solve the problem IMHO

Thanks Gav,

Definitely one of the things I will try.
