what kind of oil when outdoor temps are 32/-22f ???

[juzatheman]

-03 6.0 powerstroke

now i have 10w-30 oil in engine but i think that is little too thik at those temps.
i use defa block heater and interior heater if it's possible but allways it' not possible...

it is now just 22-40 deg. but in two weeks it drops fast...
should i change oil like 5w-40 or 0w-40??

I would change it to Amsoil 5w30. It's not cheap but it's worth it. Especially at those temps.

Mobil 1 5W-40 at wallmart

[roadrunner]

you should be fine with the 10w-30, i have already started, unassisted by block heater, at -42f

15w40 and a block heater,ive been at 20 deggrees outside and just keep the block plugged in.ikeep mine plugged in at 50 degrees,wouldnt want to scuff a bearing

[skuzzitude]

For that cold of temperature, I'd recommend a 5w40 synthetic, mobil 1 is a good brand, or the new Rotella T6 synthetic.

Block heater works great! My truck did not come with the cord so I got one on ebay for $17

[juzatheman]

yes i think i change oil to 5w-40 when temp drops more... thanks.

If you're going to plug in, get a heavy duty timer to plug the extension cord into. That way, it can come on for a few hours before you go to start up, and not all night. Your electric bill will go down quite a bit-I know mine did. That was my first winter with 15W-40.

Now, I run Rotella T6 and haven't plugged in since. -20F isn't out of the question here, sometimes for the whole month of January.

If your that cold, I would get a 5w cold. So 5/30 or I run 5/40 full synthetic.

You will get oppions on this all day long. At the end of the day, know what oil does, and what the weights mean and im sure you will pick the right one!
