    my god man,

    you are so full of yourself that you dont read what the point was.

    The point was that no two cars are the same hence your stupid test wont work. The reason I mentioned the benz was that it has a 1.5 inch thick insulation layer on the bonnet - the engine can overheat to the point of siezure but the bonnet will be "cold" to touch - you can literally lie on it and wont know the engine is blazing hot.

    The toyota corolla 2.0D also has that insulation but not that thick. Its bonnet also remains cool - then comes the radiation, ambient temperature, person health factor.

    If I get you a twin turbo mazda RX7 and ask you to check the bonnet temperature you might say that the oil is literally crap because a mazda RX7 generates heat that makes a house oven look like a fridge. You can pour all the LM in it you want, it will still generate insane heat. Because thats how its built.

    Lets take this guy - he's doing a proper test on his motorcycle (post #92) - he's a Pakistani person too.

    Im sure he could have used his hand to touch it.. why did he not?

    Notice the high temperatures, now explain to me how can you test those temperatures with your hands?

    Once again a great observation. You are Thomas Edison of Pakistan. I like your posts.
    So technically I can redline the engine for 5 hours straight with good engine oil and full water in radiator with no harm.

    May I know what you guys actually thought about the words "over driven" ?

    2.0d's bonnet also gets hot when temp gauge reaches its midpoint(normal operating temp).

    "Look the good in people and you will find good in them".

    Just ignore what everyone says here. I know people feel rather easy to taunt rather than even trying to observe it. Speaking / writing is rather easier than being practical.

    If a car is normally driven, when stop and open the bonnet and yes can feel a certain (lets call it standard) amount of heat.
    But if car is bit over driven, using bad engine oil, running short water in radiator, etc. etc. then certainly the amount of heat will be more when we will open the bonnet
    .
    please define the words "over driven"

    your post is ambiguous. Explain in "proven factors of physics/mechanics/math/thermodynamics because Im a book knowledge person.

    Yes it does because the insulation is very poor, But the question is, do you use it as a gauge to measure latent heat of oil?

    over driven is in sense that someone is using Mineral oil whom SCI is 4K. But he comes for change after driving 6~7K.
    I that sense its called over driven.

    ok - lets take that point into consideration, does the latent heat of oil change? or does the cooling system falter? - How are you using those factors to measure such differential of temperature.

    I think you are wise enough to know the results for running dead oil in engine.
    When the oil will not give the enough lubrication to the engine, then ofcoarse it will increase the internal frictions and hence will produce more heat.

    does that get out of the cooling system threshold? How are you deciding the oil is dead?

    Majority of the oils, after running few K slowly lost its lubricities, additives, detergents, etc. (whatever you call them), are fully done. Oil start becoming sluggish or gluish, etc. That means the oil is done and needed to be replaced. So if we will keep driving with such condition of oil (Over driven), that means we are killing our engine by ourself.

    But I read your other posts too and find that its your style (i-e agree to be disagree).
