This is Why I Don't Change My Oil

I actually did, Tom. I know it sounds incredible. Back in those days I typically drove about 40K miles per year just for business. At the time, I calculated the cost of the recommended oil changes and the cost of rebuilding the engine (if I did it).

It was cheaper to rebuild the engine than do the oil changes — especially true at Lincoln Delaer prices. So I rolled the dice essentially on a lark to see what would happen. As luck would have it, I eventually sold the car with the original engine still in it!

I don't drive those distances any longer (especially at current CA gas prices). Moreover, I suspect modern aluminum engines would not fare as well as a cast iron 460 under those conditions.


Postscript

Actually that may not be true ...

The follow-on vehicle was a 528i BMW that went just about as far (378,000 miles), but I did do oil changes because I did not want to tackle a BMW engine rebuild.
