I'm getting tired of replacing my spark plugs every other oil change, I wonder how many of you actually use platinum or iridium plugs.
Of course, I've searched previous threads in this site, wikipedia.com, about.com, I couldn't find much info about premium plugs.
But on sites like these, they claim those premium plugs have much longer life. Is it true on bikes? You've ever tried and found out true?
And for oils, is there any oil that lasts longer than mineral oil? I've tried synthetic, and the package didn't say anything about service life so I just assumed it has the same life span as mineral oil. I also found 'High Mileage' engine oil at store, but the package says that's for the engine which got a lot of mileage, still needs to be oil changed at same frequency.
Now you can tell I'm a lazy guy!
