spark plugs at 75000 miles.

Don't forget the anti-seize. Also, I'm doing mine about every 30k. Is that necessary, no. But it still costs about the same as every oil change, lol.

Having said that, the do look pretty good. And dang, all you guys with that kind of mileage, come drive at high altitudes with heavy ethanol and max of 91 octane and see what kind of mileage you get... Sheesh.

All kidding aside on the mileage, I just did a 7.5 hour trip (normally without crappy I70 traffic it's about 6 hours), lots of stop and go and total elevation change of roughly 16k', I still managed to maintain around 17mpg.

By “threads” he’s referring to the number of different discussions on this forum regarding spark plugs.

Oops, my bad, sorry....I really should stop posting stuff when it's past my bedtime
