I run Mobil 1 10/30 oil in the cooler months.It get into the 90's to high 90's here in the mid Atlantic in the summer months.Is it recommend to switch to 20/50 or would 10/30 be good enough?

The Cleveland needs nothing different then any ither engine.
It has never been explained where the 20/50 weight requirement came from.
10/40 is fine although I think it has been dropped from the synthetic offering for some reason.
You will see a pressure drop with 10/30 at hot idle.

Thanks for the reply,Doug.
The Cleveland was designed to operate on 20W40, that's where the 20W50 came from, as 20W40 is no longer available.
In warm weather, if you're not going to run synthetic, then my recommendation is Castrol 30 weight, with a can of GM EOS or some other ZDDP additive added to the mix. If you have a stock oil pan, run 6 quarts, rather than 5. The single weight oil is manufactured from a better base stock, with a more shear resistant molecule. You'll notice the bottle for the Castrol 30 weight advertises it as heavy duty (HD). This is true for most single weight oils, I happen to be a fan of Castrol. I know a lot of mechanics who are. Castrol will leave the innards of your motor spotless. Bitchen! Its also good at elevated temps, which is why a lot of motorcycle mechanics who were around before the days of water cooled motorcyle engines, are Castrol die hards.
Now, if you want to talk synthetics ....

synthetics......
Motor oil is controversial among auto enthusiasts, because they become emotionally attached to their selection of motor oil. The performance of motor oil can be measured scientifically, and there are differences amongst the various oils on the market. The best advice, regardless of your selection, is to change it often enough so that the color never becomes black, dark brown at the most; and change your oil before it loses it's "tacki-ness". If it starts to feel like kerosene or water, it's too late.
There are previous posts on the subject if you do a search.
Mobil One makes a 15W50 don't they? You could run that all year around. Certain synthetic motor oils seem to always come out on top, or near the top, of oil & automotive industry tests (not magazine tests) of synthetic oils. Mobil One is one of those oils. Amsoil & Golden Spectro are also frequently the top runners in tests.
The most amazing synthetic in my experience is Amsoil 20W50. I like this stuff because it has NO viscosity enhancers in it. It is by its very nature 20W50 without the use of viscosity enhancers. This is a big advantage because viscosity enhancers tend to break down faster than the base stock of the motor oil, leaving you with an oil that is the viscoisty of the smaller number. In the case of your 10W30, you are left with 10 weight oil as the viscosity stabilizer breaks down. The drawback of Amsoil 20W50 is the cost, it ain't inexpensive! About twice the price of Mobil One.
The subject of motor oil is a complex one, lots of information to present & explain. This is enough for now.

Yes this is true, in nude therapy I was so attached to my Mobil 1 that I oiled myself down with it. It has superior performance.

I agree with you George.I had a brand new 750 Susuki in the early 80's.Sold it a few years back with 20k on the speedo.Never burned a drop of oil between oil changs of 3k.

It isn't. It has nothing to do with it. You need to get past this nude therapy thing. We're talking about engine lubrication here.

Ok Doug,I think I got it.Sorry for the misunderstanding,just got carried away.Now I'm straight.You know,with Georges new promotion and everything,women, boze,new avitars,just lost it.Maybe I need therapy?
