In europe, people don't change oil as often.
I don't know if it's the industry here, or is the US oil just that much worse
in any case, it's also a matter of WASTE, in which regards the US is still quite ignorant.
in europe, people change it every 10k miles. If you're really nice to your car, you'll change it at 8k, but rarely anybody does that. People run it beyond 10k too.
that being said, i change my oil in the truck every once in a while, mostly around 6k. i don't drive that much, so i have to keep looking not to forget it.
if i knew the oil is the same as the standard oil in europe, i'd wait 10k.
on the same note, Steve doesn't change oil in his van. he never has.
the van has now 250k. he just adds oil LOL. mostly our bike stuff. go figure..
