well all. I'm in need of some advice. winter is just around the corner here. we already have snow in the mountains. last winter the truck was less than eager to start. I know there are a lot of thing that contribute to a good start ' but I was wondering if I should switch to a lighter oil. last winter days were in the single digits and low teens during the day our low was -35* or so. what oil would all the wise minds recomend? any thing I should avoid? thanks for all your your help j>

 

Do you plug your truck in at night? or at least a couple of hours before you start it? that will deffinately help, i dont switch oils, i just plug it in.

 

One Word.
Synthetics.
I run 5W30 all year round.

If don't plug it in most of the night it won't start at all

 

synthetic is spendy? is it worth it?

 

Never plug it in.

Bill

 

Ditto, synthetics are the way to go. It's more expensive but so is the engine. The cold starts are great, the noise (clunk & rattle) is almost none existant.

 

We buy Rotella 5W-40 synthetic by the 55 gallon drum and run it year around in all the engines listed below;

 

Yep I would run rotella 5W40 synthetic for winter oil. I have also had some success with rotella 10W30 in both this truck and my previous. But I did cook a turbo running it in this truck (thrust bearing). not sure if it was the cause but it didn't help.

 

delo 0-30...........

 

did you mean delo 10-30? that is not synthetic is it?

madvan.. I'm jelious I have to have my truck plugged in all winter. how cold are you average lows?

 

If you need to plug in the truck there must be something wrong. I seldom plug it in. When I do it's on a timer to save on electricity (1300 watts). Mine fires up 20-30 below, I don't see those temps too often but it always starts. It's nice to have a warm(er) truck in the morning my .02

 

migrate to tx for the winter!! enjoy the chilly 50deg days we could use some more good shoer's down here

 

so what im hearing is 5-40 is the way to go. My truck is also getting new batteries. I will check the GPs I put 8 new in a 3 years ago. also a new Gpr. I also am due for a coolant change. any thing else I should look at?
oh yeah.. how,many miles do you all run the synthetic for thank J

 

I see some split between syn 5-30 and 5-40 what is the advantages of each what should help the truck start better, is there any risk with either in warmer weather, thanks again J
