No need for an oil change?

For everyone who knows cars/engines and respects their vehicles ... I thought you would find this funny:

My son was discharged from the Army about 6 months ago. Five months ago he bought a used car with bent valves from a garage. He and a buddy replaced the bent valves and so far everything with the car has been fine. Fast forward to today to find out that my son is asking me if I want to help him change his oil. I ask how long it has been since his last change. He walks out to the car and comes back with the following:

"It's been about 11,000 miles since I bought the car and I haven't done an oil change ... but that's OK since the engine has been using oil and I've been replacing it with fresh oil."

All I could say is the "Youth is so often wasted on the young!"

LOLOLOLOLOL! I did that once when I was young, with my Mustang GT. I think I once went 14,000 miles give or take between oil changes, but I was adding a quart every 2000-2500 miles (had a drip, didn't burn oil AFAIK) and it was probably 90-95% highway miles.

does not compute. He knows enough to change out the valves but not the importance of oil change?

He's actually somewhat right, depending on the quantity of oil being added. Adding oil will freshen up the additive package.

I would consider the filter being left on for so many miles much more detrimental.

Of course, it's a bad practice overall, but it could be worse.

As Eli said, it's not quite as awful as it may sound. If it leaked or burned enough oil then really he'd never have to change the oil since he'd be replacing it with new so much. The filter obviously does get old, though.

Don't understand how people can leave oil changes so long, though. If there was a pill you could take that would extend your life appreciably and the only effort involved was that you needed to remember to pop it every 6 months or so, wouldn't you do it?

Yea, you will be getting the additives but by not totally draining the pan (when the oil is at least warm) your begging for a sludge issue IMO..

With modern cars its not the engines that die typically its everything else.
So being anal on oil when the rest of the car packs it in long before the engine does ?

Back in the 80's when I first started w fleet vehciles the recommended range was 6k miles before changes. My own cars over the last decade I only change once a year w synth regardless of mileage andits topped up, no issues yet. . .
