If your car is important to you (as it is to me) then error on the side of caution. How expensive is it really to change the oil and filter on your car? I change it myself and I spend about $20 all included. So I think I can afford to be a big spender and take a few minutes out every few months and change the oil on my car even if it may not need it. Will it break my wallet? NO. Will it waste my time? NO, because at the same time I check out everything else and make sure that my car is running perfectly. Its called maintenance folks..

Take this from a person who has never ever blown out a motor or transmission in all the years and models of cars that I have owned. I keep my cars for the long haul so I prefer to baby them.

I don't know if its laziness or cheapness but I can't fathom for the life of me why anyone who has a nice car (it's a mustang folks not a civic) would really want to stretch out how many miles you get out of that oil change. I rather have a car that is in pristine condition than one that is junk under the hood. I know 20 years from now I will still have mine, while I know many of yours will get traded or junked.
It's one thing to be a bit conservative about your oil change interval. I'd say this depends on your usage of the car, and Ford seems to agree. If you track your car on a semi-regular basis, even 3000 miles (low end of Ford's "Extreme service" interval) is too many. Ditto if it's your weekend dragstrip toy with little in the way of "normal street driving" the rest of the time.

Being wastefully conservative isn't the same thing. There is simply no need to follow the "Extreme service" schedule if your driving falls well within "Normal".

Your point of looking at long-term car ownership as justification for excessively short oil change intervals is wasted here, as I also keep my cars long term (and while I'm not a brutal, "drive it like you stole it" kind of driver I'm far from being the "gentle" driver that my status as a retiree might suggest). The cars I bought new starting in late 1971 but no longer have were kept for (roughly) 10, 33, 9, and 19 years, and about 175,000 miles each except for that last one. That last one has over 115,000 on the clock and is still in daily service (it's about two years older than its new owner - my son's oldest kid). The cars we currently own are 14, 7, and 5 years old, and there are no particular plans to replace or dispose of any of them yet.

In normal use, I've never lost an engine due to occasionally stretching the recommended oil change interval out a little. I did get caught with too heavy a grade of oil on an engine that had always used a lot of oil generally during a sudden cold snap, and I had a freshly rebuilt engine shoot straight up to 5000 rpm on its first start that wiped out a couple of rod bearings. Once each, both 40 years or more in the past, neither occurring under circumstances that should even remotely be considered parr of "normal" ownership.
