Are you one for following recommended/routine scheduled spark plug replacement?
Leaded gas has not been around for a lot time. IMO great. IMO, the tetraethyl lead is what caused spark plug fouling and running richer mixtures eventually would cause carbon fouling. The combination forced routine replacement, like in the old days 10,000 - 20,000 miles was typical.
I remember when Cadillacs recommended plugs be changed at 100,000 miles. I could not believe it.But, as I upgraded to lean running engines with fuel injection withO2 sensors, time showed me yes 100k was very easily obtained. Now, that I got lazier, my car has+140k with no replacement probably because I do not want to buy them high dollar plugs. I overhaul my other engines, so I do not have the high mileage comparison.
My goldwing is carbed and may run a little rich. I plan to only replace my plugs when necessary like on my chain saw or lawn mower. Maybe if I could get 50,000 or 75,000 on a set, I would consider replacing, but I tend to believe I will foul a plug or two sooner.
So, here is a poll. It is not engine specific.
Let's not include an occasional one plug cleaning.
