im not religious on ghanging the oil, but if i know it has been a while then i will. if i get a new car or motor i change the oil anyway.
if my motor leaks than i know it gets a mix of fresh oil often, self changing oil as you will.
i had this pinto once that burned and leaked oil out of every seam, i was dumpng anyhig from used oil from car lots to chainsaw bar oil, i cnanged the filter once but not the whole oil. it was so bad it used 3 GALLONS of chainsaw bar oil in one 150 mile trip. i even took the oil out of my 84 soob to go to work
anyway i try to keep consistent whith what i use, i like napa/wix fiters and fid the napa house brand(valvoline) oils economical, from straigh tto blend to syn. i have 10-30 napa syn in th erx now. the sedan has valvoline blend but it needs an oil change because zanny dook drove this car, his driving habits, and all the baja'n!

I would consider my use extreme conditions for sure as I start the car approximately 40-60 times per day
Basically I end up having to change my oil once a month and believe me, it needs it. I once went like 6000 miles and it was nasty nasty stuff!

Cost of oil for more frequent changes: X.
Cost of an engine rebuild: In most cases significantly greater than X.
Really, frequent oil changes are cheap, especially if you do it yourself. You're not going to hurt anything by changing the oil more frequently, but you can accelerate engine wear/damage by not changing it often enough.
Also, I prefer to change my oil more often, because I don't know what sort of maintenance previous owners have given the car. My RX-7 regularly spit out black oil until the engine blew. After rebuilding it (and cleaning it up), it spits out still mostly amber oil. I'd rather change oil more frequently to clean old crap out.
Very well put.
Most people think of oil as just a lubricant. Something to prevent friction. There is a helluvalot more to it than that. Oil is many things. It's a bearing: It fills small voids between critical moving parts. It's a cleanser: As discussed earlier, it traps contaminants. Of the many types that cannot be removed by the filter , they can only be removed within the oil....by draining it. It's a coolant: It extracts heat from internal components and carries the heat to an oil cooler, or an exterior surface where that heat can be extracted. It's a hydraulic fluid: It performs hydraulic functions like PUMPING UP LIFTERS (and we all know about that).
These things were brought to my attention years ago in A&P school. I have never looked at engine oils the same since.
Bottom line: Changing your oil OFTEN is cheap insurance.
In over 15 years as a certificated mechanic, I have NEVER seen an engine fail due to oil-related problems on an engine that was well maintained by having the oil changed in accordance with the maufacturer's current recommendations.
The way I see it, I do not want to be stranded on the side of the road in my car any more than I would want to be finding a place to land in a plane with a seized engine.
Oil is cheap.
