Winter Oil Recommendations?

Southerners pffff know nothing of winter....... Silly little people.

Unless it maintains -40 like it does here your fine with OEM weight oils. At that temp the truck never warms up and needs a grill cover.

 

I do the same with coolant and transmission fluid

 

In very cold climates, the first number in the oil viscosity is the most important. Oil thickens as it cools, so a 0Wxx will be thinner at start up than a 10Wxx. It looks like you have a 4.0 V6. I would suggest using a 0W30 full synthetic for winter use. JMO.

 

seriously though with todays synthetics. If your vehicle calls for 5w-30 / 10w-30 there is no point NOT to run the 0w-30 even in high ambient temp climates.


I run 0w-30 In my truck and it will see cold starts in ambients of 100+*f down to 0*f throughout the year depending on where i am here in socal. Even at 0w at 100*f the oil is still thicker than 30 weight at operating temp, but its MUUUUUCH thinner than 5w or 10w at the same ambient. What this means is better lubrication while the motor is warming up even at 100*f ambient.... at 0*f ambient the difference is even more pronounced between 0w and 5w/10w

 

my 4 banger calls for 0w-20, couldn't think of a better winter oil IMO!

 

So are you saying if I put extra virgin olive oil in my truck that it'll crank up much easier on cold winter mornings?

All kidding aside, good info. Thanks.

 

I always run Rotella 5w-40

 

I know my truck will last over 20 yrs instead of about 20 minutes before everything starts to disintegrate regardless of what viscosity oil is in it...............

 

That's why God created TSBs.

 

Next time you are bored and looking for fun/entertainment, instead of starting a new thread, I suggest you visit the "off topic" forums. Lots of fun and crazy stuff in there. Hope this helps you.

 

Unless you live at the North Pole just use what you've been using....
