I have 07 250 rd. I tried to change the spark plugs at 60,000km. when i took one out ,it looks like new so put it back. should be changing at 120,000km.

Does what brand of gas affect how your plugs wear?

96,000 km is the correct change interval for plugs (60k miles)

Lexstacy, the oem spark plugs are pre-gapped. No need to do anything, just pop them in and torque it to the correct specs.

I use shell v-power and shell v-power only. I only occasionally use mobil or hess as a last resort around here when i'm low on gas and shell is no where nearby. But I haven't noticed it affecting anything but I like my local shell station

I changed my spark plugs at about 59,800 miles or so and I noticed the car was a bit more responsive and idled a bit smoother but it was a very minor difference and in honesty is probably placebo.

i changed mine at 83k (yes i am way over) but they looked the same. i was told by many people i could have even gone to 100k and still had not problem. Anyway, i ended up using Denso plugs and have noticed a tremendous difference in power and the way the car rides. Taking that intake manifold off was a mother trucker but i did it and it only took me two hours. i think now that i know how to do it and what to expect- 1 hour tops. LOL

WOW i recently changed mine at 68k and they don't look anywhere close to yours. i actually thought i didn't have to replace them yet but it is suggested to do so. i didn't throw them away yet and if anybody wants to see, i could snap a pic i wonder what's causing different wear on same mileage cars
