RabidWombat Posted October 9, 2012 Share Posted October 9, 2012 I notice all of a 1.5 MPG drop(22.5 winter vs 24MPG summer) based on car computer in my wife's 05 LGT winter vs summer with her idling. She lets it idle 5-10 mins for warmup on cold winter days for comfort and defrost/safety in our driveway. She never lets it idle down. Winter blends gas also kills mileage. I drop about 1 MPG just due to the winter blend swap, and I'm in CA with the car parked in a garage. Link to comment Share on other sites More sharing options...
dr_sharp Posted October 9, 2012 Share Posted October 9, 2012 I try to let the car idle until the blue light is off. then i stay below 3k rpm until its is up to full temp. lol Link to comment Share on other sites More sharing options...
BAC5.2 Posted October 9, 2012 Share Posted October 9, 2012 I try to let the car idle until the blue light is off. then i stay below 3k rpm until its is up to full temp. I don't let it idle. I start the car, buckle up, then go. I typically stay out of boost until its up to temp, but otherwise no special procedure. Idling has no real advantage or safety factor over driving normally while cold, unless you live in subzero climates.

frank_ster Posted October 9, 2012 Author Share Posted October 9, 2012 warm up start up and drive off try not to rev above 2500. dont do any major reving untill at leas first line on temp gauge is reached. for cool down for normal driving you can shut down right away. after a pull through all the gears let it cool dow for about a 2-3min this can include light throttle driving as the cool down time. since the cars beyond stock will make more heat they should have a bit of time to cool down. since the original design of the cooling system was ment for stock power levels. yes subaru does say that the coolant is still circulated trough the turbo after the engine is off but this may be not enough after a sever beating. at 1/4 mile track the decel where no fuel is going into the engine realy cools it down when using ngine braking, then gental return road ticket booth and then to the line up or parking spot will be enough to cool the turbo plenty. 1/4 mile pull and shut off the engine at 150 mph is not a good idea for example. Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...

Alopez6337 Posted October 9, 2012 Share Posted October 9, 2012 Well living in GA, I pretty much just get in and go, Summer and Winter. No warm up idle time. I dont abuse the hell out of it, if the engine is cold but I have no problem pushing full boost on the way to work occasionally if it isnt completely warmed up. As far as the cool off time. The turbo is water cooled so I believe even under hard driving no cool off time is required. That coolant tank is pretty much keep water flowing on it cooling it off. I know that on turbos that arent water cooled it is best to have cool down time for the turbo because oil does not absorb and release heat as good as coolant.

Except, of course, increasing the chance of oil dilution with fuel as you force the car to remain colder, for longer than necessary. In fact, letting the car idle while cold is probably worse for your car than just driving it easily for a few minutes right after it starts, for just that reason. And cold oil running through the turbo is not an issue. Whether you move the car or not, the turbo still spins in cold oil. So long as there is oil pressure, the turbo is safe for normal driving almost regardless of oil temp (so long as you use an appropriate oil grade for the environmental conditions). "Thermal equilibrium" is also not something you need to wait for before moving the car. I'm not even sure why you'd think that were necessary. The engineers who design cars, especially cars renowned for their performance in cold/snowy climates, don't overlook things like this.

BAC5.2 Posted October 10, 2012 Share Posted October 10, 2012 Aww, I'd have loved to hear what kind of explanation you had to justify "taking care of your car" means making sure the engine bay is in "thermal equilibrium", and that "at-temperature oil makes it through the turbo" before you move it. Darn. Meanwhile, just keep in mind that the very thing you do to help improve the health of your car, further exposes you to fuel blow-by induced oil contamination.

quick4dr Posted October 10, 2012 Share Posted October 10, 2012 In hIgh school I did an internishio at a local Goodyear. On one afternoon a woman pulled in, in an older caravan mid 90's body. Complaining that her engine was recently louder than before, and her husband told her to take it in. I started the van to pull it in and it sounded like a soup spoon being whooshed around in a pot. Fast Forward: pop hood dip stick is broken off in tube cant be pulled out to check. Put car in air... Open drain plug, NOT ONE DROP OF OIL CAME OUT!!! Service Manager told the lady explained that likely the motor is a done, what do you want to do? We filled it up with 4 quarts of lucas and 1 qt of 10w30 motor. Motor started right up the noise mellowed. She paid for an oil change and was then back like 4000 miles later for a battery. motor was running fine. Still blows my mind Link to comment Share on other sites More sharing options...

dtmenace Posted October 12, 2012 Share Posted October 12, 2012 how about heads made from lighter materials causing them to warm faster than the rest of the block, inevitably causing gasket failure. regardless, it's better to warm your car up while driving it.
