I guess I'm one of those guys as I have always believed, just like what is written on the bottle and in the manual, that in so many miles, or once a year, change the oil.
I believed what was written/said, that any longer than a year, due to the build up of acids, etc, leaving it in any longer, could cause engine damage.
I assume that thinking was based on using old formula Dino oils from many many years ago? Funny though, but likely just a money grab, that some dealers/manus are recommending 3 and 6 month change intervals still.
Oh, I wouldn't say you're an "old habit" guy.
Now, this blurb from http://jiffylubeindiana.com/blog/maintenance-tips/how-often-should-you-change-your-oil:
Motor oil is the life blood of your vehicle. Oil’s main job is to lubricate and clean the moving parts of your engine. In other words, oil keeps your vehicle running. It is also vital to change your motor oil often. The general rule of thumb is that you should change your oil every 3 months or every 3,000 miles, whichever comes first. However, this is not always the case. Continue reading to find out why!
Since your oil cleans your engine, it continually collects buildup and particles. Eventually, your oil becomes too contaminated to properly protect your engine. When your oil is too contaminated, it turns a dark black color. This is when you need an oil change.
Additionally, you need to change your oil more often if you do a lot of stop and go driving, do a lot of towing, or drive in harsh environments. If you drive in any of these conditions, you can just check the color of your oil to see if you are in need of an oil change. Just check the dipstick. If your oil is dark black, then it is time for a change.
If you need help on how often you should change your oil, just stop on by your local Jiffy Lube of Indiana.
