Thesnufalufagus How so?I get 18mpg combined roughly half city half interstate I'm very satisfied with that.

Walkingstick And I was talking about the going up hill thing... Going 70 uphill burns gas.
08-31-2010 07:43 PM
Walkingstick I didn't know who you were speaking to dude.
08-31-2010 07:34 PM
Thesnufalufagus I was replying to pokey about my personal Experience with my i6 not trying to compare a 4and a 6.I know my jeep is not a sports car and Since when is going 70 a sports car if you go any less than that on I-20 you will be sandwiched between two 30 ton semis.
08-31-2010 05:11 PM
Walkingstick Yeah I know but... Still I can keep up with a 6speed.
08-31-2010 05:03 PM
pokey ^ 6 speed is the key here
08-31-2010 05:02 PM
Walkingstick Same with my 4cyl now. Except... I like to save my gas and besides it's a Jeep not a sports car
08-31-2010 04:46 PM
Thesnufalufagus I have a 2006 6speed i6 and I never have to downshift even up the steepest hills I can loaf around at 70-75 without even the slightest loss of speed

Yep, even the I6 stock setup doesn't do well on highway hills. It's a low end torque motor perfect for offroad. The tradeoff is highway performance.

Like Vaultzz and thecheat said, downshifting at hills is the name of the game on the highway. Even the 6 banger.

Yeah mine used to be like that before I changed my exhaust out, aired my tires up and cleaned my filters.

Walkingstick I've towed two ATVs on a good sized trailer.... My four banger did find. Hills would be a problem with two quads,,, but one would be fine. The hills I drive Are the blue ridge parkway hills.

The 2.5L engine has a 2000 lb. max tow rating with the 5-speed manual even though it wouldn't do well towing that much weight. It has the lower 1000 lb. tow rating only with the automatic.

BlackBox Downshifting at the right RPM is key on the freeway. 3k - 3600 RPM's are my sweet spot.
08-30-2010 12:06 AM
4x4junkie My 2.5 does the same and it's an automatic. I have 33's , 4:56 gears and I expect that from a 4 cyl. You and myself just need bigger engines. But don't worry off roading you'll be just fine.

thecheat I'm in a stock 04 wrangler with the I6 and even I have to go down to 4th on hills if I don't want to lose speed. It's just part of the Jeep territory

chucky cheese Never had a problem with my 4 banger. drove all over the country, hills, mountains, 80 on the texas I-10. Kept up with everybody. 6 speed manual. You have to act like an auto tranny and shift accordingly. anticipate whats ahead.

Is the drop in power going up hill normal for this, or is there anything I can do?

yes it is very normal for the fourbanger to loose power uphill im in the same boat, just get used to it.

Vaultzz Even with my 6 banger and 33's I have trouble on hills. Heres what I do.

1. When I see the hill I start to gain as much speed as possible.
2. As soon as I hit the bottom of the hill and my speed starts to drop I down shift and hammer down!
08-29-2010 07:24 PM
Bobthegod You can get a few more ponies if you want to change the stock fan to an electric fan kit. I haven't seen any specs on it but those that have done it here claim to notice a real differance in performance although slight.
08-29-2010 05:53 PM
98-4Banger i also got the 4banger and well if its completly stock best thing is just prepare in advance for the hill nothing else to do. no matter i still love ma 4banger !

YJPunisher213 I have a 92 YJ with a 2.5, a 6 inch lift & 33's. I feel ya on the highway/ hills issue. I beefed up my 4 banger and it doesnt have that problem anymore. The 4.0 throttle body bolts right too the 2.5. I also added bigger fuel injectors, throttle body spacer and a header. Hills are not a problem anymore.

I agree with you dude. I love my four banger

Walkingstick Shift down to fourth on free way, and third on non highway.
Clean fuel injectors, airfilter, fuel filter, and put on a new exhaust.
