    Was just wondering - what would be the highest, harmless RPM on the motorway on a long run?

    My 2010 Corolla 1.4 driving 100km/h is on 3,000 RPM... 130km/h and there's almost 4,000 RPM, quite a lot.

    Can I drive on 3,500 RPM for like 200 kms?

    There's a couple of older thread that mention what RPM people are doing at motorway speeds. 3500 sound fairly normal although most get less.
    Here and here.

    Certainly. 3,500 RPM for an hour or two won't do it any harm.

    If engine is in fit state (regularly services) there absolutely nothing wrong with driving at 4000rpm, or even 5000rpm or higher.

    In user manual of most cars, it states that revolutions withing red range on tachometer, shouldn't be maintained for longer periods.
    If you are below red zone (and an 4000 or even 5000rpm) you are way below it, your driving should do absolutely no harm to your car.

    I've drive good few times through Germany, and kept revolutions at 5000 - 5500 rpm for few hours nearly nonstop. Except from ridiculously high fuel consumption there was no damage to the engine.

    I generally would keep 4k or under for the van

    But thats easy to do as its 6 speed 115 so 2500 is 80mph

    On the bike for long term I try stay under 10k revs. Stay out of the powerband like lol
