Well, the folks in Arizona have had hotter temps than those of us in North Texas but I think steady highs of 100+ qualify as hot.  I have a 48-50 mile round-trip commute and usually take the freeway for about 2/3 of it.  I haven't run into any problems but I will admit to using a pure synthetic 15w50 oil as a means of hedging my bet in these conditions.  I change it every 1500 miles.  I may decrease that frequency in cooler months but it's my belief that frequent changes of good quality oil (dino or synth) of appropriate weight are a good way to help extend the life of the engine.

here in yuma, we have certain bragging rights, "over 100* over 100 days straight" is one of them.  it was 118* a couple weeks ago, we're having a cool spell this week 102*-105*, i ride every day. we also have several old vws, i run ALL my air cooled motors a little fat, not black fat but milk chocolate fat, run very good oil, change it often. one of my vws has been a daily driver for 11 years and has nearly 100k on it, nothing but valvoline 10w40w in it since day one, and it is still clean as a whistle inside.
    with the equipment properly prepaired, riding in the heat becomes a personal issue. debby doesn't ride too much, this time of year. personal protection becomes the greater concern. short rides to and from work (6 mi @) short sleeves, jeans & boots. long rides leather chaps, jacket, full face helmet, all to reduce dehydration, the leather keeps the wind/heat from sucking the moisture out of you faster than you can produce it.

I live in the DEEP south and it gets hot and very humid here in the summer. The winter lasts about 2 weeks. I run 15/50 year round.  I change every 2k and my ride is 14 miles all city. I do take some extended day trips on the weekends. Most average out at a 150 trip with a combination of rural, city and highway miles. I have trip coming up in September that will take me beyond my normal runs. To say I'm eager would be an understatement.

a little extra hot weather info:  get some old CD's & glue them together for a kickstand plate. It's the  pits to park your bike and see it sliding down in the melted asphalt & tar. I stuck an extra long shoestring through mine so I can hang the end up where I can see it so I don't forget to pick it up. Over 100' for too long to count now

I tip my hat to those of you in the South who routinely ride when the temp exceeds 100 degrees. Up here in the Great Lakes Region we rarely see such intense heat, but we have experienced it for several days and counting now. I gotta tell ya, It's too hot to ride. I'm waiting until it cools down.

Thanks to everyone for the great info advice.  Mainly I did not want to hurt my bike and now I feel much better about riding (and parking) it when it is hot.

I feel stupid...I don't know what oil I put in my bike last...I went to the Suzuki dealership and got what they told me to get and put it in...

The manual says you should change the oil every month regardless of how many miles you put on it...maybe it says every month or every 1500 miles...I only live 10 miles from work so I don't put 1500 miles on it in a month...should I still change my oil?
