I was reading an article in the local paper the other day regarding cold startup damage. It stated that starting a cold engine will put the most wear on an engine. I can't really remember why this is so, maybe something to do with cold oil being pumped right on back into the pan leaving some parts high and dry? Anyhow they recommended the use of engine oil heaters wether it be the simple dipstick type, or a pan heater or otherwise. From what I remember they also said to use not only in winter but through the fall and spring also. Well as I was looking through jcwhitney I found a dipstick style heater for $10. Since jcwhitney is going to stop sending me catalogues if I don't buy something soon I was thinking of trying it out. Are there any drawbacks to trying it? What do you guys think?
