To me, that means they have to load the motor to its rated power when they perform the fuel consumption tests.
Edit: actually, I believe they bolt it up to a small engine dynomometer and run it through various load points that reflect how the motor might be used in the real world.
Well that’s the problem lol, what application will give you hondas quoted fuel consumption figures. if its using double it’s a 100% more thirsty than what’s on the spec sheet.
Any updates on the IGX800, do benefits outweigh the fuel consumption? By Sunday, I’ll either purchase a new IGX800 or another tried and true gx690. Also, I’d be open to taking a tip on where to buy. My last 8 gpm is a Pressure Pro… I just hate the fuel tank that came with it.
Know where the best price is for a 690? Cheapest shipping?
From what I have read on a couple Facebook groups (for whatever that is worth) they seem to be doing much better on fuel that what @Innocentbystander experienced.
@djpws Dustin, I purchased my Kohler from Carroll Stream Motors (Buy Honda GX690RH TAF 22.3 HP Gas Engine On Sale With Electric Start) and they offer free shipping. I thought their prices were competitive and they have a good selection, so it might be worth checking out.
Has there been any improvement in the gas consumption on the iGX800?
Honda has not given my vendor any software to program my machine so my fuel still sucks I’m not even running it now
Hotshot, Man, I liked your comment. If I had known I could make money doing p.w. in 2017 when I bought my Generac 3200, I’d a shopped around more. I bought it to do my (ex-wife’s) house. Then I realized there are lots of places here that need p.w. It is an ancillary service I offer in my tree service work.
Been over a year now. Do you still have the iGX, or did you give it back to your dealer? The fuel consumption issue is concerning.
I still have it. Hard to turn down free 
We ended up putting an 8gpm pump oil instead of the 10. That brought the fuel consumption down from a little over 2gph to 1.5gph. it’s still more than the 690’s, but it is what it is. Keep in mind, all this numbers are worn the injector in line. Without the injector fuel consumption was better than the 690.
You’re saying that without a downstream injector the iGX engine was more fuel efficient? Do you have an explanation for why that’s the case? I’m not very good at understanding some of this cause & effect stuff.
I don’t suppose you did a flow test with the 8 gpm pump? I don’t know which pump you have but I’ve seen a few guys report 9 to 9.5 gpm with their GX690’s & 8 gpm pumps.
They’re probably bsing. With just a jump hose and no nozzle best I’ve seen is 8.7
Injector causes restriction, more fuel consumption. 250ft of hose was about 7.5 gpm with 3k at the pump.
