10w60 for South Florida?
I'm in South Florida.
Have any of you Florida folks ever use 10w60 for its better heat protection instead of 20w50?
I've got Amsoil 60wt in my 81 shovelhead and 20w50 in my 2010 RK and both have been running just fine.
But seeing as how temps down here can get a bit nuts I'm wondering if I should change.
I see Motul 7100 synthetic Ester 10w60 online.
Your thoughts please.

I would not run straight weight oil in anything in the year 2024. There is no benefit.

One advantage is they last longer due to there being less additives (less viscosity modifiers). Additives break down faster than base oil, thus the straight weight oil will maintain viscosity longer than a dual viscosity oil.

Most wear occurs at startup. It was 45 degrees when I rode to work this morning. Straight weight oil has no place in anything driven on the street. If it's hot outside every time you ride and the straight weight you choose is a good fit, then it's probably not going to hurt anything. But back in the real world where I ride to work in 45 degree weather and ride home in 80+ degrees, the protection of multi grade oil is a no-brainer.
Most of the claims in these oil threads are not things in which I'd engage, but this one is a matter of common sense. There is just no reason for straight weight oil in 2024.

I have sent my oil to the lab having run it way beyond the drain interval and I have never had one come back outside of the viscosity range. While your answer may have been theoretically true in the days of dino oil and the chemical viscosity improvers they had then, as a practical matter those claims have no merit today.

Maybe OP only rides in the evenings when it is >80*F?

Even if he does, there is no benefit, but probably no harm, either. The same would probably be true if we were talking about a generator that ran day and night at a consistent load and temperature.
