I don't always agree with some of the members on the forum, but I've never gone so far as to say their input was useless. Even if I felt it was, I don't see a need to say as much. Just seems counterproductive to me. Now, @billiebob has a different way of looking at some things, sure, but it's those differences that keep this forum interesting. Even your little tirade (I'm sorry, but that's what it was) had entertainment value, if nothing else. But may I suggest that as a new member (not suggesting you're new to Jeeps, just to this forum), you might want reel in your aggression a bit, especially on your very first contribution. Makes a helluva first impression, but maybe not quite the one you'd really want to stick with you. I don't know you, and I'm not judging you, but I am defending another forum member's right to say what he wants to say (and yes, ultimately, even yours). For all I know, you drive a pink and green zebra striped TJ that gets exactly the mileage you say it gets. You go, dude! Ain't my kind of thing, but post up pics and tell us about it. @billiebob has made many contributions to this forum, and I suspect most folks here hope he continues to do so. Keeps things interesting, ya know? Have a great day, friend! And welcome to the zoo!I've tried to withhold by not making an account as long as I could.... Are you ever going to quit with this bullshit or no? I see you consistently talk about Audis and their top speed in 5th, 6th, 7th, (less than 8th gear) and blah, blah, blah. Nobody cares. We don't drive Jeeps with 8-speed transmissions. We drive Jeeps with 3, 4, 5, 6-speed transmissions and the highest gear is the .69 overdrive in the 4-speed that I know you are definitely aware of. Your comparison to Audis is unhelpful at best. Jeeps are several things: unaeroynamic, non powerful, and are run with way larger tires than any Audi ever will. Therefore, Audis don't compare to anything we do. We don't have multiple gears to hit redline in and even if we did, it would still be difficult in the lower gears and impossible in the higher gears. We also aren't going 150 mph. Your comparison to Jeeps with the Audi is stupid, and a huge waste of time. With your logic, why don't we go ahead and start comparing to Corvettes?
Second, Your gas mileage claims are WAY off. I've seen you consistently talk about 20-25mpg. You are in Canada. Something is wrong in your conversion process because literally no 4.0 TJ or YJ driver is getting above 20 mpg, no matter what their gear setup is, even including your beloved 3.07 gear setup for forestry roads. After converting to US quantities, we stick to about 14-17 mpg on the highway, as far as 3.07 to 5.38, regardless of engine or transmission. I personally think you go off of Canada KM claims and pretend they're the same as mpg which is way off. I've done the math and while you claim MPG, if you convert those claims to KM/g or KM/L, it lines up way more realistically. I think you haven't figured out the conversion process quite yet. It's real similar to your son who you claim gets 30 mpg in his JK. BULLshit. Until you figure out the process for calculating proper MPG, you should quit making claims about what setup makes such and such MPG. Learn your countries difference before making claims on the scale of the US.
Third, please quit convincing people to join the misery that is you. You for some reason seem to think that 3.73 would give you some sort of magical experience....it won't. If it would, don't you think you'd have a bunch of people agreeing with you and following your ignorant advice? Well....you don't. And, for good reason. Riddle me this, Batman. If RPM was directly related to gas mileage, explain why my 31" tire and 4.0 5-speed AX15 Jeep gets 18mpg going 65 in 4th gear at 3100 rpm (GASP!!!) vs going faster at 70 mpg in 5th at 2600 RPM? Your logic doesn't make sense at all. And please don't start with the whole you get 23 mpg in Canada quantities because that doesn't compare equally to anybody but Canada and the messed up numbers you come up with that don't convert to US numbers.
The fact of the matter is your numbers are way off, your experience doesn't match anybody else, and your input frankly is useless. Nobody wants to subject themselves to intentional power loss, especially when so many people are gaining MPG and power at the same time when they regear, regardless of what you say. The only people losing MPG when they regear are the people that start hot footing it when they regear. I don't blame them, I had bad mileage when I regeared also and the new power made it enjoyable enough that I wanted to hot foot it and lost mileage as a result. However, my mileage on the highway was the same or better because my engine wasn't working as hard and I kept my foot consistent. There in lies the beauty of lower gears.
The reality of all of this is you should gear for about 70 at 2800 and 75 at 3000 if you can for a 4.0L engine on the highway. For a 2.5/2.4L engine I would say more around 3200 at 70 and 3400 at 75. Anything else truly isn't ideal and I sure wish ignorant forum members wouldn't ruin that for anyone else.
