Amsoil, Royal Purple, Mobil 1, etc. All very good oils. Amsoil can be a pain to get as it's not sold in stores. A lot of riders use Mobil1 since walmart carries it.

Sometimes availability is an issue for Amsoil. Mobil1 and Redline are good oils.

I was just stating my view, and reasons why I don't run it.

Opinions, that's all. I'm not trying to sway anybody.

These air cooled motors can sometimes get hotter than the average water cooled car. Viscosity is a huge priority for me.
Some of this is simply a mental state, a feeling of confidence for me.

Since I don't understand motorcycle engines (or any engine for that matter) I have to listen to someone I trust on what to do. I chose those people to be my two indys who were HD dealer service managers of 12 and 14 years.

They still have me running dino oil and changing oil every 2000-2500 miles. Their recommendation is not to generate themselves money because they don't do the oil changes every time and when they don't they sell me the oil at their cost plus 10%.

Lots of knowlegable folks here and in the Harley world and they have completely different ideas. Go figure.
Oh my god, you're using a non-synthetic oil?!!!!!!!!!!!!!!!!!!! Your bike will run hot and blow up, haven't you been reading all the facts? This 100 year old design of an air cooled engine can't survive without Synthetic oil. These oil threads are just like a train wreck, I know better but still click on one from time to time, my fault. Back to your regularly scheduled syn oil hype.

Opinion please:

With my gear drive recently installed this winter, AND the noise typically found in Twin Cams, AND the fact that last year we had 90 days over 90 degrees down here in NC. I'm thinking to switch from Mobil 20-50 to heavier 60 Wt Synthetic just for the summertime.

Is it smart to do given a Twin Cams design?

For one thing, your bike will run hotter. I don't recall anyone saying it would blow up or wouldn't survive. This engine design isn't 100 years old either. The basic design of the twin cam was introduced in 1999. Your engine will survive with dino, but mine will survive longer with synthetic. Mainly because it's a fact that synthetic lubricates better longer and it's a fact it will run cooler. Those aren't opinions, those are facts. If you think your engine with lubrication that is inferior to mine, and your hotter running engine will outlast mine, your dreaming.

The Twin Cam is not a 100 year old design. All oil is run internal now. You do not have oil lines outside of the motor. The V-Twin is a 100 year old design.

Also Amsoil is sold locally. Maybe not in the area of the poster who posted that, but if you went to an Independent motorcycle or ATV store I bet you find it. I can find it in about 10 locations around here. From Indy shops, ATV shops to tire shops. All carry Amsoil local.

If I lived in Arizona I might consider it in the summer, but other than that I wouldn't. (Just me). I don't think straight 60w would be healthy in cooler weather. Make your motor work harder, might counter the cooling aspect by working harder. I can't prove that. Just a theory of mine.
We had the crazy August heat up here last year too, so I can relate to your question. If anything, I'd shorten the change interval after riding in much of that heat. A quality syn should hold up pretty well.
