If you are using a conventional oil or semi-synthetic why not use the age old 3000mi interval? The stuff is cheap! I hear all of this debate on the internet, in articles, etc. about using your oil longer, but we spend more on a tank of gas each week than on an oil change! Think about it. Why are people so desperate to extend their intervals when we go though gas like crazy (but that is okay [well, except for the price gouging])?
A freaking cartridge of printer ink costs more than an oil change!!!!
I use synthetic oil in everything. If the car has a decent oil capacity (like the Focus) for its engine size, use, and output then I change it every 5000mi and use a good quality filter (Motorcraft or Mobil-1). If the capacity is low (like my wife's Protege 5 at 3.7 quarts) I change it just like conventional oil (3000mi).
If it is a high performance vehicle that is driven often (like my old Lightning and MS3), I change the synthetic at 3000mi.
It is cheap insurance. We are not killing ourselves financially by doing so. Your car will last longer as well.
Even the "saving the environment" argument is silly...oil can be recycled!
I am not ranting at you, but just in general. I see this debate all the time, and I just don't understand it. I'm as poor as the next guy, but I have no problem spending money on oil. I see it as insurance against bigger repair bills down the road.
For what its worth, 3000 miles is overkill these days with these kinds of engines.
BMW recommends at 6000 miles, sometimes more because the engine is that good at managing everything.
Yes its only, maybe upwards of 100 a change; but unless you track your car every other day I don't see why anyone needs to swap oil every 3000 miles.
