Glow Plug Life Expectancy ??

[ruffdog]

After reading many threads about the subject of anti seize, I have seen no clear answer. Some say not to use anti seize at all, while other's recommend different types of anti seize. They all say not to goop it on thick or get it on the end.

Had 225k miles on my '99 7.3 Ford before needing glowplugs, 2 crapped out about the same time. My 2001 Mahindra 4110 still has the originals at 3196 hrs.

Glow plugs should last decades and thousands of hours. If you’re burning them up annually then there’s an underlying problem.

EXACTLY. The op has something that is causing GP failure. If operating correctly they should never have to be replaced.

In my case, 6000 hours on one M9 (new in 2002) and 4500 hours on the other (new in 2001) and they work just fine and I expect them to last basically forever.

Never had a glow plug fail on my 13 y/o B7800, or the Kubota engines in my zero turn or RV generator. I did have one glow plug fail in a Ford 350 Powerstroke at ~90,000 miles. I'd say GP failures are fairly rare.

Glow plugs fail for several reasons with high heat being the most predominant. Kinks in the inner coil can cause higher resistance and thus more heat. You change out your relay or gp controller at all?
Could be a substance in the fuel treatment you're using making ignition hotter and may erode the plug but primarily, a good dual coil glow plug should last for decades.
Cheap ones cannot and do not go the distance.

could they be activated all the time as in never shut off?

In my Mahindra 3616 the glow plugs lasted about 6 yrs and around 500 hrs if my memory is correct. Mine cycle every startup and I do lots of start and stop cycles.

Either you have something wrong with your system or
you need to change brand of glow plugs that you have
been using.
Are the gp's the same brand that don't last long?
