well, I usually roll a few cigarettes for the road, put directions on Google maps, and adjust my seating/coffee/whatever else I need to be comfortable. In total it takes a minute or two.
Like that ever stops anyone. Georgia is a hands-free state (not really because people eat, do makeup, and whatever else), but I always see people on their phones while they drive.
Letting the oil circulate for a bit, adjusting fan-settings, A/C, selecting music etc. If it’s wintertime I let the car warm up for a while while I scrape the windows.
Waiting for the engine to warm up a bit? Centering myself and dealing with distractions before I drive. Mapping out my egress routes and bailout locations after eliminating the parties specified in the verbal contract? All normal things you are supposed to do before you drive.
You are absolutely not supposed to do that. In fact, you’re supposed to do the opposite. Letting your car idle to warm up kills it faster because the oil pump isn’t running because the car isn’t moving.
The exception to this is:
A) when it’s really freezing cold out, and then still not more than a minute (not “at least a minute”. No more than a minute. 30 seconds is plenty in winter. To be clear, if it isn’t cold out, this doesn’t apply, and you shouldn’t wait at all.
B) if your car is ancient, like with a manual choke or similar. Well over 40 years old.
This is 100% correct. There’s a lot of “tips and tricks” that are extremely out dated, and typically for vehicles prior to the implentation of fuel injection.
The oil pump is running but it is generating less pressure at idle.
You should however keep the revs lower, not as low as idle as you point out but also don’t red line it. If it’s a turbo try not to generate lots of boost either.
The car doesn’t have to be in gear for the oil pump to run. If the engine is running the oil pump is on. That’s why there’s a red light that looks like an oil can when the key is on before you start it but it turns off when the engine is running because there is oil pressure. If that light is on when the engine is running you need to shut it off immediately or you’re going to be replacing an engine.
Oh so if the manufacturer says so? So it’s not in fact a myth or lie? With three exceptions.
One thing I have found really annoying about Lemmy is there are tons of trolls just here to be contrarians. I’m here for debate and to learn. But so many people are just assholes, miserable in their life and looking to bring down everyone else. Unnecessarily rude.
to be fair, the last point more so covers margin cases that are more likely to be covered if the user/driver informs themselves than trying to list every margin case here.
You are absolutely not supposed to do that. In fact, you’re supposed to do the opposite. Letting your car idle to warm up kills it faster because the oil pump isn’t running because the car isn’t moving.
That is absolutely not true. The engine runs the oil pump, so the pump is working as long as the engine is spinning, assuming the pump is not faulty, of course. I’m not aware of any car engine ever built where that isn’t true.
That being said, idling your (modern) car for longer than a minute, or as long as necessary to defrost the windows in the winter, is a waste of fuel and, consequently, emissions. It’s also an unnecessary wear on mechanical parts, but not because the engine is cold or hot, but simply because it’s in use.
Adjust seat from when my husband used it. Adjust mirror from when my short husband moved it Put laptop bag down into the passenger footwell Fish can of drink out of my bag and put it in the holder Put phone into holder, turn on Bluetooth Turn of Bluetooth speaker Connect car Bluetooth if it hasn’t happened automatically Choose podcast or music Seatbelt on Set wipers if needed Pull away! Takes a minute, roughly
