It would be NO Surging, NO block heater ( should put one on though, it's better for them) NO additives, and it's left outside in the elements. For the last two weeks around here that has been 4-6" of snow per day ave. with a few over 8" and one day of 9.2". Outside temps have varied from single digits up to almost freezing, or would that be thawing at this point? Wind chills down near zero and slightly below for the last week.
Starts right up, runs a little rough for the first 45 seconds to a minute then smoothes out. But hey, with temps like that I run a little rough first thing in the a.m. too!

BTW I have a new car as of this afternoon! My '76 300D rolled over the odometer, I now have a new car with only 18 miles on it
