Default It's winter, so how do I set my car?

One thing I recently realised, was that compared to the summer, it's much colder in the winter. Theres always a lot of talk about keeping cars cool in summer, but what about the winter?
One thing I would like to know: I understand that the shock oil thickens as it gets colder, so how much softer an oil should I change to to get the same performance?

Trial and error.
Start with the manufacturer of the oil, they will have all the break downs if there is any.

It also depends what brand of silicone oil you are using, I know AE oil and maybe some other brands don't get thicker or softer, and they stay consistent throughout the seasons. You may be able to compensate by running a piston with smaller or less holes.

Don't believe what the bottle says, all oils thicken or thin with temperature changes. Its one of the laws of physics. Silicone oils are not affected as much by temperature as other oils, but the effects are still significant.

Go here and read this, the part concerning temperatue is at the bottom btw.

saying silicone oil doesnt change viscosity is pure popicock. this year Josh Cyrul was testing oils from different brands for the great lakes challenge.(a gas race) every day this year the ambeint(sp?) temp was in the upper 80's, lower 90's. after 5 mins. on the track he said his car felt like crap. he checked the oil and it was pretty much water. the only oil that really didnt change was team losi.

there you have it.

Wow! That article shows a 30% or so change in viscosity. Good to know.
I have another winter based question:

Battery warmers?

I think what Cyrul found is that viscosity under a work load would need to be about 3 or 4 times the rated work load. In order for the viscosity to be a factor. In rc electric it would take to long for the viscosity to break down to that performance level.
Wheres the oil manufacturers? Dont they read these post, Help!
I think viscosity is in the work load break down and not the weight.
Every oil will thin and thick'n.

I'll say this if it sound's like to much science For R/C racing.
Maybe?
I dont think we can put enough science in it.

A little rc for thought:
When we put a limit on what we will do, we put a limit on what we can do.

Silicone is far more resilient to temperature change.

As for setting up, a nice scarf and fleece to keep you warm, sod the car.
