Hi folks, with these temperatures I've had to plug in my '84 300 D (182 k) all week. It starts on the first try. I commute 100 miles a day from NJ to NY. The problem is the return trip from NY. The car sits in a parking garage all day and struggles to start for the trip home. Can't wait for it to reach 32 degrees.
Liquid graphite has solved my frozen lock problem.
brrrrrrr,
