Folks have widely divergent experiences with glow plugs. Some say they last 10s and 10s of gallons some only get a dozen flights. They are a little temperamental and lots of small stuff can kill one. But once you are tuned in right, have no starting errors (hydro lock, hot starts etc) a plug can last at least several gallons. I only change one if its dead.

Plug killers
Too rich, too lead, Hydro lock, hot start, dirty air intake, ATV from muffler connections, Temp lean out in flight, the list goes on.....

Best pratice.
Use fuel tube to get it started

If it does not rotate smoothly STOP, no excuse to strip out the head threads, EVER

Dont touch the tip

check to make sure the old copper washer is removed. You may end up w/ 2 if you dont

If you are getting fuel and air and it wont start, its the plug. Cranking your motor for more than 15-30 is pointless. If it does not start in that time frame, find the problem.

+1

So always carry a few spares

Obviously a no start can be caused by a blown glow plug, but often they communicate by not idleing. Change the glow plug and many times it will once again run fine.

Multiple glow plugs failing after a short period of time (less than one gallon) is a sign of bad engine bearings.

Try different types and brands, most common are the OS #8, but the OS #7, Enya #3 and #4 are ones to consider.

The glow plug, engine compression, engine needle settings and fuel all have to match.

I run os #8s on both my OS .50 and my OS .91 C-Spec and really don't think that I changed them from early this spring. I only change when they go bad, which they probably will now that I posted this.
