    Mobil 1 0w-40 HT/HS

    <blockquote>quote:<hr />Originally posted by moribundman: <strong> I'm latching onto the HT/HS, because that seems to be one of the more important points regarding an oil, at least if you work an engine hard. If I seem obesessed (and obnoxious), rest assured, it's just to beat some more...

    Mobil 1 0w-40 HT/HS

    <blockquote>quote:<hr />Originally posted by Cary: <strong> <blockquote>quote:<hr />Originally posted by Patman: <strong> No matter how you slice it, a 3.6 HTHS for a 40wt synthetic oil is pretty sad. Pennzoil's conventional 10w40 has a better HTHS! Amsoil's 10w40 is much better too, 3.93. It's...

    Mobil 1 0w-40 HT/HS

    <blockquote>quote:<hr />Originally posted by moribundman: <strong>Doesn't sound good to me. Why do I even pick an oil that meets the required HT/HS of 3.5 (in my case), if the HT/HS isn't stable? </strong><hr /></blockquote>moribundman, I don't understand why you are latching onto HTHS. I'm...

    Mobil 1 0w-40 HT/HS

    <blockquote>quote:<hr />Originally posted by moribundman: <strong> And how does HT/HS change with age of the oil? </strong><hr /></blockquote>I don't know. My best guess is that HTHS viscosity would change with age like any other viscosity measurement, i.e., "stay-in-grade" or thin or thicken...

    Mobil 1 0w-40 HT/HS

    <blockquote>quote:<hr />Originally posted by moribundman: <strong> If the listed HT/HS refers to new oil, then how do we know an oil won't shear below what's required to meet the car maker's requirements? Seems scary, no? </strong><hr /></blockquote>A viscometer is used to measure viscosity at...

    Mobil 1 0w-40 HT/HS

    <blockquote>quote:<hr />Originally posted by moribundman: <strong> <blockquote>quote:<hr /> One thing to also remember, as the oil thins out, it's HTHS gets even lower. So if 0w40 has an HTHS of 3.6 when new, at 14.4cst, just imagine what it'll be once it has thinned out to 12cst. <hr...

    1.8T VW oil weight

    <blockquote>quote:<hr />Originally posted by moribundman: <strong> They do use low HT/HS in the newer 1.8T in Europe? I stand corrected.

    1.8T VW oil weight

    <blockquote>quote:<hr />Originally posted by moribundman: <strong> As I understand it, Audi (and VW) switched in '98 to "Longlife Service" in Europe. That means, they went from VW502.00 spec oil to VW503.01. Pretty much the only difference between VW502.00 and VW503.01 oil are some additive that...
