I've always put my Merc on a block heater whenever it drops to 4 and below. At home its on a timer and at work its just plugged in. The valve cover is warm when I touch it, and it starts like in summer. 
What I like is that it warms up quickly too, which again, reduces wear and tear no? Mine has now got 567,344 km on it now; gets me 8.8L/100K and this morning at 4 degrees, started right up with no block heater (I stop the block heater as soon as it hits March). |
My car doesn't have a block heater, but starts up on the first glow with 358,000 original miles. I use 5w40 in the winter (change during fall break and spring break over my school year).
