Winter oil weight ?

Well it is getting that time to change oil for winter, here in ct. it gets anywhere from 0 to 50 degrees what is the right weight ? I went looking for 10 w 30 but I could not find it, what does everyone think. Or should I keep the 15 w 40 in it ? 2000 psd 4x4.

This is one of those questions that everyone has a different answer for.

I use the 15-40 Rotella T works great!!!
As long as you plug your truck in when it gets down to the 20's and below it will start just fine. (if you cant, hope your GP and GPR and Batterys are on good working order)

I really want to switch to synthetic... just to lazy to do it... he he

If you can't plug in go to the 10W30 Most truck dealerships should have it or truck stops. Just stay with a major brand of oil and be sure it is CI-4 rated. I've seen people put in automotive 10w30 by mistake.

I run delo 400 15w40 in the summer, and then I usually run rotella 5w40 in the winter. Right now I'm trying out the Mobil 1 5w40.

Both the Rotella and the M1 are pretty close in per/qt price at wallmart. A 5 qt jug of M1 is ~$20 and a 4 qt Rotella jug is ~$14.

Yea I run Rotella 5w-40 in my truck for the winter - it definitely made a difference in how easy it starts when it is really cold outside. With 15w-40 in the truck, it would lope and idle rough for a good couple minutes. With the 5w-40, it starts like you just had it running an hour before, and I haven't had it lope at all yet. Definitely worth the bit of extra $$ for it!

I used the Mobil 15W40, since I've only owned a PSD for 9 months I really can't tell how well it works in the cold, but I've been happy with it in the summer! Syn, from what I hear is good, but I'm a believer of the dino oil! Synthetic oil makes the truck run quieter.... and in a neighborhood full of "BMW driving yuppies" that's not something I want! lol
