I don't think the engine itself cares much... but my fuel gauge sure seems to know the difference.
:|errI drive and tow with a diesel so the intercooler cools the air down anyways
approx 7% loss in power from 85*-115*.If you ever spent any time on a dyno, atmospheric conditions DO matter to your engine.
I always try to be out on the I40 at night,but today have to leave early,always think about is the wear and tear different in high heat,even when the engine is running at normal temp.Dumb ? i guess but something i think about.
. I'm more concerned about getting a flat tire and having to change it in that heat.
I always have a floor jack and tire spinner for long trips with trailers. Last thing I want to do is use the factory supplied crap.Agreed. Changing a tire on the hot black top on the shoulder of HWY 40 sucks. I carry a large blanket for the dog to sleep on in the truck and its there in case I have to lay down on it. Floorjacks are great too!

My 09 gas engined Chevy 2500 runs at 210. Night, day, sunshine or rain, 210. Yes, the mileage IS affected when running up hill in 100+ temps. I have found better fuel economy by dropping to 5th gear, (I have 3.73:1 rear gears), and allowing a few more Rs to keep the engine loafing along instead of being loaded down up that Needles grade in 6th.........When "AIR" is harder to find, the modern computer controlled fuel systems pull back on fuel delivery. Less air, less fuel, = less POWER. It is almost on an even graph, drop percentage of available air, drop percentage of available power. This does NOT necessarily apply to "boost" assisted engines as you can pack in more air with turbo/blower. I'm just not sure how a computer can change boost while you're going down the road. A blower needs the pulleys, (overdrive ratio) changed mechanically......And still needs the fuel system dialed in to that change. Modern technology has changed a bunch since the days of overheating 50 Mercs and "Desert bags" hanging off the front bumper......Damn, I'm old......Ray
Really? You're saying the engineers purposely mis calibrate our temp gauges? If so, I feel better knowing the temp is actually lower. However, the gauge never moves after it come up to 210*, up or down........RayOne thing that I learned when I started using the Edge gauges was that our trucks do not run a 210* like the dash shows, they run at about 190* according to the OBD2 computer and my gauges are updated every 2 seconds about. It's kind of crazy how dumb the engineers at the auto companies think we are.
With it that hot and dry, you loose power. So does your boat. If you still drive at 70, like you do when its 80* out, your are asking your motor to work harder. The harder your motor works, the more heat it puts out.
Just turn it back a little in the high heat.
