My crankcase right now has about 5-1/2 quarts of PYB, 10W-30. That weight is OK down to about 10 degrees F. But it is getting iffy at 0 degrees F. The sump officially holds six quarts and can take some over-fill.
In about a month, I will go up to an area where the 5:00 AM lows are around -10 F to zero F.
Do you think it will do if I just haul along a quart of Marvel Mystery Oil to put in the crank case and thin it if need be? How much would this thin it? I am just concerned about morning starts when it has been cold all night.
