Re: Oil Change (A Little Long) Wife Sent to me, she thought it was cute
Perhaps divining this story a little would help.
When one changes ones oil filter, you get a fresh quart or so of oil. Out of most engines. Little four bangers might only get half a quart, plus another few ounces that drips out.
And I've never had an engine, up to 200,000 miles of service, that needed more than a half a quart added between six month oil changes.
I'm suspecting some of these "I never change my oil!" deals involve putting a quart or two in every thousand miles or two.
Bottom line is, after you've partially worn out the rings and valve seals, you're smoking your oil change out the tailpipe and adding in fresh at about the same rate. Difference being internal friction, heat, engine life span and gas mileage.
Not a very good thrift idea, unless you swap cars every few years or are leasing for 3.
There is an "old guys" mindset around changing the filter and adding oil to their 1930's and 40's cars. Pretty much the same thing...the oil filters of older cars held a quart or more, and they smoked off a quart every thousand miles or so.
