that is quite extreme. what about when filling up with petrol? dont you have to take the key out to unlock the fuel filler?
As I dont turn it off, the ignition is hard wired on. the only way to stop it is with a form of kyriptonite. Or disconnecting the battery.
They do that on engine durability and oil quality tests too. That's why a BMW engine with 1 M simulated driving miles and good oil has virtually no wear when they take it appart for inspection after
They also do it on Lada taxis in Russia - suck the old oil out every 2k while topping it up with fresh, cheap, mineral oil. Every third change they actually stop the engine and change the filter too. Those Ladas do half a million miles with no problem....
thats a rubbish test. it does not factor in lots of cold starts, short trips. in short, they got it up to temp and left it running... wow, that proved a lot. didnt leave it sat outside in the rain for components to get corroded and nasty. hell... my mk2 is on about 195k real miles and is doing fine. nissan did a test about 10 years ago where they ran a 2.0 engine for days absolutely flat out, manifold was glowing bright red etc i think they were trying to kill it and it wouldnt
Yep, but most people are quiet impressed by the: This engine's done 1M Miles on this oil with minimal wear story... Then; the rest is boring.....
Even further back than 10yrs ago, I recall seeing a Ford video with a cvh lump on the bench. It was similarly run on the limiter day after day.
Constant running is OK as it is stop/start hot/cold extreme load that will cause stress and wear on any mechanical component.
