Hahahah - bingo! I know that technique well. On extremely cold mornings (~minus 50), I can actually hear the lube begin to spin in the transmission as I (slowly) release the clutch. That was on my old '69 Chevy pickup; I never experienced anything that cold with the '07 Outback, and this is the first winter with the Escort (coldest so far is about -25F). I am not even confident the car would start at -50 - even after a few hours sucking electricity.

Hello All,
 
I have had my 2009 Forester 2.5X 4AT for three months, now. I love this car -- best car I have ever had -- no problems, so far.
 
I have been reading the forum with interest. One question I have is:
 
When you are refering to the engine being "warmed up", are your refering to the blue light going out or some other criteria.
 
Here in West Virginia winters are not nearly as severe as many of you are describing, yet, the cold weather effects are quite noticable.
 
Thanks for your comments. I have learned alot from these forums.
 
Bill

Ah, the blue "dummy" light. I think I would find that annoying - I like gauges.
 
In my experience, the engine can warm up at different rates than the rest of the car. In terms of engine operating efficiency, the blue light turning off is a good indicator that the engine is warmed. But, in very cold weather, accessories and drivetrain components, like the transmission and differentials, could take longer to warm as it is all based on heat-by-friction. The more they turn, the more the fluids warm, but the colder it is, the more heat is required to warm them to normal operating temperature. The parasitic loss on the engine is all a matter of the fluid viscosity (resistance to movement). Therefore, the lower the viscosity of a fluid at a given temperature, the less energy will be used to move that component. In a differential or transmission especially, that translates to more energy at the wheels.
 
When choosing fluids for a vehicle, you want to go with the fluid that will give the best protection at the lowest viscosity within a given ambient temperature range. Fluids that work best at extremely cold temperatures are not likely the ones that would provide the best protection at extremely high temperatures (typically >100F), so I would not likely put the same fluids in my car here in Fairbanks, Alaska as I would in, say, Florida.

But don't forget that tranny fluid needs some viscosity to work properly. Tough to strike that balance without feeling like you're mixing cement with the shifter when it's 30 below.

Right - ATF is always a problem in cold temperatures. That is one thing that blows me away about the transmission in my Escort. Manual, but uses ATF???? Hmm.
 
All automatics are winterized here with a pan heater on the transmission. Manuals are not, as the fluid can (should) be swapped out with an appropriate gear oil.
 
Amsoil universal ATF has the best cold-weather properties I have found, but even it will get very gummy at -50F (according to the temperature ratings - I have not experienced those temps with the Amsoil yet), but at least it is still quite fluid at -30F, which is a far more common winter temperature here than -50!

Sounds useful. Had never heard of dry lube before. Thanks for the explanation.

Sometimes you'd have to crank the engine extra long and the battery would get so low the specific gravity would drop so all there was left was frozen water, buckled battery plates and ice ooozing out!! Or someone might offer to give you a push to get started and the tires wouldn't turn over and you'd do a tandem slide until you found a spot of dry pavement so friction would make the wheels move.
One real cold night I went into my dad's garage and found a can of mobil one and a can of ten thirty. the 10-30 wouldn't pour and the mobil one poured slowly like molasses.
fun days......

Snow and ice build up in wheel wells by mwasnidge

The cold and snowy Wisconsin winter has finally hit! I had actually been looking forward to the snow so I could test out the fabled AWD system the way it was meant to be used, and I have to say, it blew me away! This is the first AWD vehicle I have driven in Winter and the difference is night and day.
However, I have noticed that even on a 10 minute drive to work through 4 inches the accumulation of packed snow and ice in all four wheel wells is just unbelievable! To be expected I suppose and normally wouldn't bother me, but I got the rugged package and if I try and kick the ice off, the flimsy splash guards and wheel arch moldings feel like they're going to come away with the ice even with the lightest tap.
It was to the point where I could hear and feel the packed ice rubbing on all four wheels, and when braking the noise was awful. Unfortunately I haven't got a heated garage, so it's going to be spending the majority of the Winter outside.
 
Anyone else finding the same with the splash guards? Any tips or suggestions?

havent been in the snow yet but one of my mud guards fell off from hitting a bump- they are flimsy and only held on by one screw and 3 plastic rivits. the body of the forester seems thinner than most cars, if you barely lean against it, it will bend. runs well but cheaply made. the interior scratches really easy too. just hoping the engine/4wd is not going to fall apart like the body

Up here in the U.P. it happened on all my cars. Road vibration, heat from the tires, and road salt will usually keep enough of a groove so the tires won't lock up. Sometimes after a long straight stretch you will find it's a little difficult to turn from the ice on the sides. Nothing to be alarmed about, just be prepared for it. Sometimes a chunk breaks loose when you are moving and can sure make funny noises until it breaks free. I've never had any serious trouble on any car from the build up.
