I've been going with 7500 miles for the past ten years.
Thought it was common knowledge. Shrug.
I thought so too, but reading that article shows how manipulative car service places are. It's a shame people are so naïve, but I imagine I'm just as guilty in other areas - if you don't have direct experience with something it's easy to accidently perceive someone as an expert when they're not, then follow their advice.
I thought reading the owner's manual was also common knowledge. Where it specifically tells you what kind of oil to use and when the change it. Apparently I'm one of the few that actually take the hour (or two) to read it... the number of things I've already seen on a website for my new car that I just think 'yeah, well, if you read the owners manual you'd realize why you're having that problem' is astounding... and these are supposed to be the 'more' informed people about the car...
For years always changed mine and recommended the 3000 mile interval. I've seen first hand the results of trying to go too far between oil changes.
With today's technology you can go further, but 10000 miles and beyond is pushing things. I do my cars at 5000 miles now.
I believe in the old saying, "Oil is cheaper than machinery."
I'm in no way qualified to speak as to what is appropriate for others. I worked at jiffy lube for a summer, and I do my own maintenance on my vehicles, that's about the extent of my car knowledge (ie: not much
)
It all comes down to how the car is designed. With new oils and machining technology things are being designed much different now than they were even 15 years ago. There are quite a few cars out there that are designed to go 10, 15, or 20 thousand miles between changes. It all depends on how the engineers of the car built the parts to work together. They built them to work a certain way, and with high end cars they build them to last 200k miles. (my understanding is even the lower end vehicles should go 200k without any problems these days)
I'm one for doing things how the engineers of the car designed them - not the service guys at the local dealership. There's a reason the people that designed the car put what they put in the manual...
