    That's basically how I do my air. If it wears too much on the edges which I hate I just add more air. Although I've moved to nitrogen to avoid variables such as outside temp and speed as much as possible. Keeps the PSIs more constant instead of it fluctuating.

    I understand, it's just I've had people question my logic for, well, a few decades, now.

    It's really noticeable on a two-wheeler, when 2PSI can make a very obvious change in pretty much everything.

    No - 5W-XX flows a bit better at cold start - the final number: -30 is the warmed-up running engine oil viscosity figure.
