Again this is not the case with modern engines, especially those with alternators & electronic voltage regulators.
I have heard this one but I don't know where that came from at all - even antique engines with straight generators and point regulators didn't over charge unless there was some malfunction.

500,000 is just getting "broke in".

Diesels are not as efficient as their gas counterparts.

Diesels are slow.

Diesels are high maintenance.

300D gets "40MPG".


Oh.... And I am just about sick and tired of seeing this one in any MB diesel classified ad. "Great for Veggie oil Conversion"......

Go pound some sand!

Rudolf Diesel's great grandfather was Chinese.

I bet you have not heard that one.

You must run 5W40 synthetic motor oil in the Winter.

No it was peanut oil. Originally he was doing work with coal dust, but he had issues sending it into the engine.

Before the coal dust it was an ammonia/steam mix and it 'blew' and didn't hold together. The coal dust worked but TOO WELL. In Zwickau there is an auto museum (not just there - Stuttgart, too.) with some photos and actual pieces of Rudy's industrial engine. They got it running and when they throttled it up, it blew sky high and took out half a city block.

OH! I forgot...

There is no such thing as an engine "running away." All you have to do is turn it off.

This is not a myth- it is true. I have a friend in the cesspool business who almost stalled the engine in his Mack one day, but in reality, the engine had stopped, and was spun backward by all the torque wound up in the drivetrain. By the time he realized it (saw exhaust from the air filter), it had already spun a rod bearing. A Mack "Pedigreed" rebuilt engine solved the problem-$18,000 later.

Spinning a bearing and replacing an engine doesn't seem like running. Maybe Mack forgot to put in the "any which way you can" oil pump -

I'll elaborate - Some people think you can run the engine in EITHER direction, and using reverse on the transmission will allow you to drive forward. Where that came from? Maybe a mechanic talked about an engine that malfunctioned from backward rotation from start up or shut down compression (often start up) but the "oh $hit" got lost in the conversation. It's a lot like kick starting a Harley after a rebuild and you didn't quite get the cam timing right - it often ends in a trip to the ER for a broken leg.
