40W oil causing wear problems over 30w?

As far as prelubing the engine before start up goes, do you
really care that much?
I do. Race mechanics do. Aircraft mechanics do. The US Navy does.
Listen to an engine upon startup with heavy oil in it (even at
summertime temps) and hear all the grinding and banging and clattering
going on inside the engine for the first ten or fifteen seconds, let
the engine warm up a couple of minutes, shut it off, restart and
listen again.
If you can't hear the difference, replace the battery in the hearing
aid.
You guys are too funny....(c;
The grinding, clattering and banging is because it's a D-I-E-S-E-L!!....The
blue smoke, too!
Cold cylinder walls condense the fuel spray as the piston exposes it. Fuel
left in the cylinder explodes on the next power stroke before the injection
takes place, especially if it doesn't start right away.
It's not a high-performance, electronic engine in a goddamn Cadillac
Escalade or Lamborghini, you know. It's an old, slow compression engine
running on home heating oil!.....even if it's got a new jacket to make it
pretty with a big row of model numbers to impress someone who just paid a
lot for it.....
If you ever get a chance, stand in the engine room of a big diesel-powered
ship when the compressed air injection start goes off....hee hee. Your
little Yanmar or Faschetti or MTU is the same engine....(c;
KNOCK-KNOCK-KNOck-KNock-Knock-knock-knock-knock......................clank!
What a beautiful sound!.....
