Never had a problem with cranking speed with any Modil 1 weight. My cars always spool up instantly on those 0 degree days. Had 15w40 Delo in the SD last winter. It was fine until it got below 20, below that you really noticed the drag.
This winter I might try some 0w40 in the SD to see what I gain. |
I thought that the slow cranking in extreme cold weather was caused by voltage drops. because the battery is not working well at low temps... I hope you are plugging in your car to keep the engine warm in extreme cold temps...
