What do u do?
Start your truck and let it warm up 5-10 mins,winter time?
Start your truck put it in gear and go?
a friend and I were having this discussion just the other day maybe we can get some outsiders point of view
Thanx

 

My Dakota I fire it up and as soon as oil pressure is good I'll start going. There's really no reason to let it warm up. I don't rod it around until it's reached operating temp though.

My 86 Ram I have to let warm up for 2-5 minutes or it'll stall as soon as I put it in gear. Plus the carb needs to get warmed up or it'll ice and die.

My 5.0 I have to let warm up too, but not more than a minute. I'm not sure why that is, but it has a lumpy cam and it doesn't idle right for 30 seconds or so after cold start.

 

yeah just what horation said, oil press and go..

 

if its cold out ill let here warm up a 3-5 minutes then take it easy on her till i get some temp on the gauge. if its hot out persay sumer time then i wate till i got good oil pressure and all the dashlights go off throw her in first and enjoy the warm summer goodness going bye me as the warm air blows in threw my rolled down window

 

Just fire it up and go, huh?

and you might just change your mind.

 

Now, maybe it's because the guy has a Ferrari and is obviously brilliant, but it sounds to me like he's talking out his ***.

So 0w-30 and 10w-30 are both a 10 viscosity at operating temp? [sm=confused06.gif]

He's just flat out wrong there. They had a viscosity of 30 when at operating temp. Perhaps he's tripping himself up with talking about thickness figures of unknown scale and viscosity all at once.

According to howstuffworks.com, in a multi viscosity oil the first number is the base viscosity, and when heated to operating temperature it thickens to behave like the second number by uncoiling polymers.

He is right though, in that if you're supposed to be using a -30 weight oil, any -30 weight oil will have the same viscosity once it has reached operating temp, but I'm not sure I agree that you can never have too-thin of an oil when cold, if tolerances cold are wide and the designers had a thick oil in mind then it's possible that you could run into problems running a really thin cold oil.


Oh, and no, I'm not changing my mind based upon that. I get in, fire it up, fasten my belt, and get myself situated, by that time it's pumped enough oil through.

 

Yeah. I thought the same thing until I did some research, and spent some time at http://theoildrop.server101.com/cgi/ultimatebb.cgi
It all made more sense after I found out when he's talking about oil thickness of 10, he's refering to a viscosity measurement called Centistokes. He just never uses that term, which is confusing at first.

 

I have a remote starter, so when it's cold out it gets 5-10 minutes to warm up whenever possible (to and from work, school, etc when I know when I'm leaving).

 

95% of the time mine gets about 5to 10 minutes warm up time at the least. the way i look at it do you just turn the water on in the shower and jump right in no matter what the temp is or do you set it to the right temp? Just because oil pressure is up doesn't meen that the flow is at peak and the oil is everywhere it needs to be.

 

Living in the south, lo temp winter starts are seldom a big issue. However, it is always good to let your vehicle warm up a few minutes when the temps are below 32. Be sure you're using the right oil for your areas conditions. Thicker oils don't flow as well in the winter. The newer trucks require 5W30 weight oil. I have been using 10W30 Mobile One Syntec from day one. It works well in any temp over 0, and keeps friction to a minimum. Also don't set your defroster to wide open first thing if you have any winshield dings......I lost a windshield that way after setting it wide open and walking off for 10 minutes. When I came back, the windshield had cracked all the way across the bottom. Hope this helps.
