There is nothing wrong with cutting diesel with gas. We did that running big trucks in arctic conditions for years. The owners manuals for many European diesel cars have right in them that it's OK to blend up to 30% gas. Only thing being if the weather starts warming up, you want to start cutting that mix back down with some more diesel or drive with a light foot
I've had many times in a big truck after using crap like power service or fppf and gelling up where I've had to go grab a bunch of gas and dump it in both tanks to get going again
