Re: Ash deposits on 912ULS spark plugs
Dan,
Not bad! Looks so much better that the first photos you showed with the grunty plugs.
If I recall, Decalin states the recommended amount as a minimum.
Maybe this is a legitimate example of "Mores Law"....If some is good, more is better and too much is just right.
I think you convinced me to increase the amount of Decalin I use when occasionally burning 100LL.
Good work.

LOL! By the time I zero in on precisely the right amount of Decalin, we will have lead free aviation gas at all our pumps. In the meantime, on this next plug change my experiment is to use 50% more than recommended rather than double the recommended amount.
