Re: Marine Lubrication
How long to warm up an engine?
I did some research and some feel excess fuel dilution and more water in oil is the result of excess idling.
SO ...excessive idling is NOT a good thing..
..agree with this?

Re: Marine Lubrication
no big deal in something w/o a cat. would rather have the thing idle too much than not enough!
the big exception to this is if you run w/o a t-stat!
if we are talking about a vehicle, your automatic transmission will appreciate a good warm up more so than your engine will!

PENNZOIL GT PERFORMANCE RACING 25W50 - 50 WT.....Performance applications. We have never had a bottom end failure. ever. With proper oil clearence and PSI this stuff works great. No Synthetics.

....if "premium" synthetic based oils were not around as they hold up to heat better and have more film-strength...

You need an oil that mixes with gas and keeps down a good film to survive for long under these conditions.

Noing nothing about blowers, I have heard that before but it never made sense to me. If they are running that rich that they are diluting the oil, why arent the rings and cylinder walls being destroyed from lack of lubrication? Everybody knows you cant run with that much unburnt fuel in there because it washes down the cylinder walls. Well??

Gas and oil mix and you do get lubricity...when you hit 5% gas or nitro-methane you are heading for trouble..so I am told...
