When was the last time you saw -40F,(windchill makes not difference in the engines temp...)
grease and not thick oil? wow who kew.lol
From what ive read most of these guys are plugging them in when it is above 30F
,,,lol
so you"re telling me you don't plug her in at -40F?
at -32 i did a little test the other year.
I started with a cold soaked engine -32F.
then i plugged it in, let it cook for 2hr. came back and the oil was at 69F, and the coolant was at 102F.
but then. i wonder why or how all of those engines ever lasted over a million miles before synthetic oil was invented?
i'm not saying it is not easier on the starter or batts to run synthetic,
i think the biggest reason is for ease-of starting as diesels got a bad rap for not starting in the cold, I dont blame the oil, i blame weak batts for this.
if this oil was so thick as hear, (its as thick as grease), i bet the oil filter would pop right off, as this grease couldn't pass threw the filter.
but that if it is as thick as grease in cant run back down into the pan...
I know, i know, the book says this and that and we know how most fallow the book..
. as it says not to tamper with the emissions, or to modify it in any way....
Remember almost 20% of that QT of synthetic is conventional as there are no synthetic additive packages, its the same additives that are used in conventional oil.
and before the amsoil or 98% of the other synthetic oil folks jump my boat, remember there are only 2-3 refiners making all of the synthetic base stock. Amsoil makes nothing, they just blend in a additive package to the base stock they buy.
Its your money and engine, your engine will last just as long on conventional oil. and most of you will never see -40F or anything even close to it.
pss if i believe all the synthetic hipe, all those diesels that we ran 15w-40 conventional oil in all winter long in northern MN should have blown out seals and ground them selves up from lack of lubrication when we started them cold (unplugged) at -60 degrees F. that was recorded just up the road.
