Hi guys, I am enjoying my first D/A but with winter coming on I was wondering if anyone has installed an esbar engine heater on the duramax. We had temps below -50 last winter and my truck sits on the street quite a bit and I'm not near a plug in. I have been reading about the synthetic oil vs dino oil debate and now am not sure what oil or viscosity to go with for the winter. With 15-40 in the summer my oil pressure is 80+ just off idle with a shot of power-up in it and I am afraid of blowing the filter off in colder temps. Any advice would be appreciated.

Where are you from? Minus 50 cold.

Central Canada. -54 celcius with the wind last Jan. Lasted about 2 weeks. A vehicle cools down real quick in that temp. I drove an import diesel last year and had to leave it run all day.

Where in Central Canada? I am in Manitoba.


Talk to Greg (lunduytG) from http://www.lubespecialist.com He is a supporting vendor here and is very knowledgable on the Espar products. I am considering putting in an espar heater as well.


I ran Mobil Delvac 1 5w40 synthetic last winter. It helped the cold starts a lot. You can get it from Walmart or any Esso dealer can order it for you. Great stuff. I might try Shell Rotella 5w40 Synthetic this winter.

Thanks, Max, I work in Winnipeg so I will give Greg a call, I know some ctd guys that have the esbar and it works great for them. I am due for a oil change now so I will give the Delvac a try as well. I am getting 600km on a tank full, every tank full so it will be interesting to see if the syn. help out in the milage dept. Thanks again.

Cool. That is 5 of us now from the Winnipeg area. We'll have to have a gettogether some time. http://www.dieselplace.com/forum/smileys/Big Smile.gif

Espar heater are the cats meow. Have installed them on Duramax's and I need to get the one I have on the self installed on mine soon. Those that have bought them are really happy they did.
