An american using metric measurements? Good to see you s are finally getting some sense
You seem to be forgetting that oil flow, fuel atomization, and comfort aren t the only reasons to warm your engine up. Consider metallic expansion. Aluminum pistons are going to warm up a lot faster than the cast iron or steel cylinder liner and the engine block full of coolant. It s better for the engine to warm up more slowly so the pistons and engine block expand at a more similar rate. When you start and just drive off, the piston expands much more quickly than the cylinder causing it to fit more tightly, and in turn creating more wear and in some engines even causing permanent damage. Just ask anyone who drove a v gm car in the mid to late s who didn t warm them up before driving. They had a lot of piston failures due to this metallic expansion. It s still better to allow your engine to idle for minutes before driving off in cold weather. Oil change interval should also be shortened a bit in this time due to the extra contamination.
Not that accurate seeing as the hood was open the whole time
Ok. Now are you saying that you dont need to let the engine run and warm up due to engine oil has no problem flowing? Im trying to completely understand this. What about piston ring gap and cylinder wall differences between a cold engine vs one at operating temp? Cold idle vs normal op idle difference? Why does oil get contaminated? How much fuel bypasses rings at first start up till rings and walls expand to normal at normal temps? Help me out here?
Realistically it would warm up a little quicker because your hood would be closed.
Normally you would have the hood closed. Should make quite a difference.
I put a brick on the gas pedal as soon as i start it up, then go back inside for a couple minutes. If you keep your engine on the little red part of the rpm meter it means it s heating up red heat. Go on and try it out, it s great, the car will be warm in no time!
Here, even in winter temps never go under degree c. Should i use w xx?
I strongly disagree on not letting your engine warm up. Getting heat into the engine is not just for oil viscosity, even though the oil filter bypasses all the oil when it is cold, but more for filling the cold gap in the rotating assembly. Cast aluminum pistons, hardened rings, cast iron cylinders and crank, soft insert bearings all expand at different rates. As well as brass guides against valves. All contributing to blow by, loose tolerances and contaminates running through the oil passages. If nothing else just letting the car warm up for sec will not allow the car to go into closed loop which means you are working your o and cat over time with the rich mixture in the exhaust and wasting gas. Personally i let my car warm up at least min even in the summer. But at least we agree that you need to let it warm up. Cheers.
Your coolant temperature will rise way slower if you turn your heater core fan wide open as well. In my civic on a really cold day will actually drop from operating temperature at idle with the fan on full tilt. I usually keep the fan on low while driving to get my engine to operating temperature faster on really cold days.
Why does an exhaust make tink tink tink noises as it cools?
Electric pre heater of engine and interior. I got it in my car and the engine is about celsius wheen i unplugg it and start, and nice and warm inside.
My neighbor warms up his work truck in the morning by starting it up and then just starting to rev it up, great idea hahaha
The flir thermal resolution is
Florida is full no more
It helps warm the engine when you start lightly driving
Florida is a hellhole. I would rather be in a place where it s !
Thanks very interesting this. Could you do a turbo car as well?
Who else could tell what kind of car it was from the thumbnail?
