I was thinking about getting the truck out for the possible upcoming snow. It has been very cold here in PA and was advised against starting the truck if the engine is too cold because the oil will not lubricate well.
Is this true?
I would love to get the 4WD working

I've never heard of such a thing as oil not lubricating well. Sure works better than sawdust! I think thats a bunch of bull!

BTw - Where is Newmanstown?

Newmanstown is in Lebanon ounty, Live just north of Lancaster County.
I am guess like the minus 20 might be worse, but teens to 20's not

Cold starts are hard on a engine,hence the reason engine heaters are used in cold climates. Oil gets real thick in below zero weather,and takes longer to get to the vital parts. Watch your oil pressure gauge on a below zero start,you'll see how lomg it takes to build pressure. As for starting it in cold weather,it won't self destruct just wears out faster. And if it does start don't rev the motor let it idle till it warms up. Good Luck.


You could borrow Nicks propane heater and blow hot air under the motor for a half hour to get it to start better

Ahh, I see you were mentioning below 0 temps. I was commenting on our normal temps, which are normally not below 0.

They are here, at least lately. Regularly below 0 overnight, and that's in Western MA. Makes for awesome skiing - keeps the tourists off the slopes and out of my way.

Cold weather is harder on any engine, starting & running in general. Most of the wear on any engine takes place during & right after start up. Running the correct grade of premium quality oil for ambient temps is vital. Synthetics are the better choice.

Charles,
Which synthetic oil would you recomend for the M37 and for that matter the M35 multifuel?

As far as I'm concerned, Royal Purple is the best synthetic out there. Around here we run the 15-40 grade. That may or may not be the best grade for you during winter months, depends on how low your temps go.

In my (former) part of Illinois, we usually ran 5W40 in the winter and straight 30 weight in the summer in most vehicles. The "5" portion of the 5W40 made starting a lot easier and allowed pressure to come up faster. It may not be available in warmer areas, but if you regularly get sub-zero temps, everyone will have it. Don't know if it's available in a synthetic, though.

Thanks for all your input
