Spark Plug Change Interval

Postby am3098 » Wed Jul 27, 2016 2:09 pm



The spark plugs were changed in my 1500 about 35K miles ago. The bike seems to run good and fuel mileage hasn't dropped off, but I'm just curious of what the recommended change interval is for plugs on the 1500?

Thanks,
AJ

My manual is around here someplace but the number 8k sticks in my head only because it seemed like such a short period. I'll try to look it up. :D

Yes sir, every 8,000 miles is what is specified.

I always wondered if that was a misprint. In today's world with much improved plug technology it seems like you would be disposing brand new plugs.

My last change was at 20 k.

I have 23000 on my plugs, just checked... Gap is still good and plugs look OK. I cannot see any reason to change them every 8000 miles....

Looking back over my maintenance records, I change my plugs and air filter element on average every 50,000 mi

Average plug today is good for 100k. If color and gap are good there is no reason to change. I've changed for the sake of maintenance only to get less mpg. Platinum plugs I think run better after 10k and remain consistent over the long haul.

I changed the plugs on my 97 right after I got it at about 30,000. But they looked fine. On my 92 that I bought back in 92 I changed them at about 50,000, never noticed a difference in MPG or performance. I think I changed the ones on my 02 at about 30,000, just because I was doing all the other maintenance at the time. Actually the plugs on the 1800 are easier to change than the 1500.

Not the $2 NGK we are discussing here.

Wearing of electrodes can be seen at about 40k mile range with the conventional plugs that are in the 1500.
