"Finally, emission controls and unleaded gas have cleaned up the crankcase which is why modern engines run so long without blowing up. In fact, motor builders have to engineer failure into modern engines so that they have to be replaced. A million miles on an engine is entirely possible given changes in the computer program cells and sturdier parts."

Yes. But there is another major factor involved that has nothing to do with any technology. Attempting to compare J.Q.Public passenger car operation of the last 20 years to any such operation of the 1930-1970 era is grossly lacking in objectivity.

Not uncommon to find modern cars less than 3 years old with 30K miles or more. Some 15 to 20K miles of driving per year. Such high mileage driving habits rarely occured 40 years ago unless it was some traveling salesman or fleet delivery operation which would not be in the realm of J.Q.Public operating habits.

Therefore, the engine stopping and starting and heating and cooling cycles of modern driving habits is much less frequent than of some 40 years ago.

I'll certainly agree that modern tech has significant impact on better longevity of modern engines but modern tech is more sensationalized than the reality of various other factors not related to tech.

ANd at what cost is the modern tech???? $700 'brain boxes', $20-$40 spark plugs, EFI, $300 in tank fuel pumps .... THat list goes on and on. Mite be cheaper to replace an engine every 120K miles. Maybe not.

THink about that the next time anyone is out there on the side of the road, broken down, trying to live life from a cell phone, plastic card and an auto club extended waranty program. How many of those SPARE $700 computer boxes do they caryy in the trunk???? I keep a $10 set of points in the glove box. J.Q.Public probably scrap the car after 15 years anyway. No???? I sit rite here and watch them go to the crusher everyday. Some of the cars look better than the tow car pulling them in. But that's a whole different real world issue in itself. We'll see in 3 or 4 years who really cries the tears.
