I use Penzoil in the JT. I use Amsoil in my rally car (bored/stroked EJ engine) and my 450 Supermoto/Enduro. I DO use Supertech Motorcycle oil in my 230cc Chonda (Hawk DLX from Amazon, has EFI with GM ECU and Denso injector and MAP sensor and some in-house branded O2 sensor) since it doesn't...

Assuming stock tire size? You have a diesel first of all, so you're already making 2-3x the usable torque us gassers are, and a lower RPM redline. Second, you COULD use manual mode in the hills and not have the "issue" you talk about with gear hunting in hills. OR just let the truck do it's...

Sir, the average of 29 and 12 is 20.5, not 24-26 (teasing). I have a stock JTW, 6 speed, 3.73s, 255 MTs, AND live in the hills/mountains, and I still see 17-20mpg average in the summer. And I'm not babying it all the time either. Still sliding corners a couple times a week, playing in the...

I know this is a diesel thread, but my 2021 gasser had the same issue when I got it with 27k on it. Kept running hotter than I thought it should, checked the coolant reservoir and it was low. Topped it off and a week later it was still low. Filled the radiator one morning, then the reservoir...

Try using manual mode and going up that hill in 6th without allowing it to shift, it will take longer. 10mpg for 3 seconds is still better than 10mpg for 15 seconds. Autos are programmed to keep your engine in its "efficient" range based on requested input. You wouldn't want to lug the engine at...

(TL:DR at bottom) As an engine builder (full disclosure, I specialize in Subaru builds and have been getting more into small engines like dirt bikes), I've tested a few brands of oil over a decade and have done some BlackStone testing. In my time I've learned: - Unless you change the oil...

Wait until you find out why modern engines since EFI blow up when stock vs modded correctly...EPA regulations. - "Yeah, I KNOW this tuning is bad for the engine, but it's great for emissions with the devices we make everyone use to reduce said emissions. What? No I KNOW running AFRs 18:1 IN...

Not an ad, but I worked for Fenix Auto Parts in Palmyra for a while, they only take in vehicles less than 15 years old, and we had a JL wrangler come in my first day. They're also nation wide, so they probably can source you a manifold for your diesel pretty easily. FYI, even used parts are...

I don't get towed, I usually DO the towing. Pulled 3 vehicles since winter, trailered another and a motorcycle at the same time. And pushed a girl's car from an intersection about a week ago (she keeps running the engine out of oil until the light comes on). I need a bumper and winch, been a...

I've been getting gas from different places to test that theory, no luck...including different octane ratings. It's actually getting worse, or maybe it just gets worse with lesser throttle input than I initially thought. Time to check filters, pending codes, and live data. Any recommendations...

Has anyone used this in their Gladiator yet? Seems too good to be true for increasing Torque limits and throttle response. Or have you tried it in a 3.6L V6 Wrangler JL? For those who have, and played with the settings, what are your thoughts and for the Torque/Throttle functions, was it worth...

I seem to vaguely remember hearing about a dealer that tried this, issue ended up being exactly what I said: profits vs cost. Yes many come out for MOAB, but nor daily, not enough customers outside the busy season. Investors wouldn't invest. Plenty of interest, just not profitable for "modern...

Someone has been watching the puke-gold/green/yellow wrangler driving over cars with 37s again, huh?

It's based on your trip meter and previous combined instant/averages. If you reset your trip meter (either A or B) every fuel fill, you'll notice a avg mpg meter below it. That's what your average is based on. I use Trip A for my avg, and Trip B for actual testing/monitoring of...

It's like hitting a wall then back to normal. Complete loss of combustion for a split second. Common with bad MAF, but it's only got 48k miles on it. My 2002 wrx MAF had 170k+ before it started stuttering. MAF cleaner is a scam, since all MAF sensors in the last 20 years use the "hot wire"...

The issue really here is finding a dealer that A) gives a shit, and B) employs quality technicians, not mechanics (aka parts pullers). I'm in a similar situation where dealerships don't want to honor warranties nor be held accountable for their actions. Dealing with corporate currently. For...

This is illegal! If you have paperwork started for the repair process, and every dealer withing reasonable distance is backed up PAST the warranty expiration date, they CANNOT revoke the coverage. The dealer was made aware of an issue while under warranty. You did your diligence to get the...

There's regulations on how much distance is required between dealerships, and that distance can increase when there's a low population density vs miles between cities. That and/or not worth the risk having multiple competing dealers that close by with so few potential customers. It's all...

NGL I didn't read all the replies. There are 3 battery manufacturer, globally, that supply automotive batteries for the US market. Generally the same battery you get from Interstate, is ALSO the SAME BATTERY as Walmart's Everlast (Platinum), Autozone's Duralast Gold, and AC Delco. They're made...

Que the required Cow VS Jeep airflow diagram, please. Anyone?
