How did you decide on your engine?

[mwilk012]

The thing is, I'm really not. I know it's something to watch out for on direct injection motors, and have never stopped looking for evidence that it's going to be a problem on this specific engine. This is why I specifically asked about the 2.0 here. So far, I have not been able to find anything specifically showing the severity of carbon buildup on a 2.0. Is it building up? Maybe. Will it be a problem at 100,000 miles? Maybe. Could the buildup be so slow that the piston rings fail first? Unknown.

This is Schrödinger's intake valve. It can be thought to have massive carbon buildup issues, and no carbon buildup at the same time. Nobody knows until you look in the box intake manifold.

Since we're going there, the owner's manual does have a maintenance plan on pages 431-433 in mine. It goes up to 150,000 miles & 15 years, yet states nothing about intake valve cleaning as being "part of standard maintenance on these engines". Now, maybe I haven't received my maintenance manual yet, but I'm not even sure sure such a thing exists. Please post a link if you have it.



You may be correct, but we have very different definitions of speculation.

Anyone with a high-mileage out of warranty 2018... your input is needed.

They also don’t recommend servicing the transmission. See how that goes for you. I suppose you probably don’t work on vehicles for a living.

Couldn't find that maintenance manual?

Like everything else on the vehicle I'll be following the manufacturer's recommended maintenance until there's evidence that it isn't enough (either due to personal modifications, vehicle abuse, forum failure rate, etc.)

No I don't. Why? Is being a mechanic supposed to give me more credibility? In my experience, mechanics aren't exactly known for their honesty.

I would argue that none of the current engines are the way of the future. I will be shocked if an all-electric Wrangler is available. I personally plan to simply convert mine when kits become available through the aftermarket. I figure the motors will have reached damn good efficiency, but more important battery technology will have improved with solid state being an option.

Pull the engine and fuel tank, hook the motor up to my 6-speed manual, install the battery and switch out the ECM and I am ready to rock n roll. I love my Jeep and why do I want to start over on customizations when it will be exactly what I want in less than a year. The other benefit of waiting is the charging network will be much more robust in 5 years.

That being said, if they come out with synthetic fuel I will just keep filling up and forget the electric conversion a bit longer.

Our electrical grid is decades behind being able to support the majority of vehicles being electric. Electric cars are still at least 20 years away from being the norm. The battery technology isn't there. The ability to mass produce batteries isn't there. The raw materials needed to mass produce batteries simply doesn't exist in the Earth's crust.

I don't disagree that there will likely be an alternate source of fuel utlized for vehicles but I don't see electricity as being the end all source of "fuel."

My 2Dr Rubicon with the 3.6 E-torque is downright quick! 23MPG combined IS GOOD TOO!

Nope. There are 4 things there that wouldn't be on an etorque. Heat exchange, cooling lines, pump, and battery cables. Non-etorque will have an alternator instead of a generator, so +1 -1, an aux battery instead of a battery back, so + 1 -1. And I'm not counting the different battery cable and wiring for the non-etorque aux battery cables. Still not seeing the huge complexity being added. Maybe it's just me. To each their own.

There seem to be more ESS problems leaving people stranded than eTorque. Not sure about the 2021 model but ESS was somewhat problematic in 2018-2019 models. Usually battery failures. Most of the eTorque components are covered under the Federal Emissions warranty which is longer than the drive train warranty.

Several things here. As far as the 2.0 goes or any DI engine. Run Top Tier fuel. I promise you will be happy you did when you hit about the 60,000 mark. I see so many engines that need a top end clean cause they used regular gas. Of course they are the same people that say it’s all the same gas regardless of where you go. WRONG, like I posted earlier. The US government mandates a set amount of detergents in fuel. Top Tier stations add more because several auto manufactures got with them to help keep DI engines running smooth. Google Too Tier fuel and a list of stations pops up.
Next thing. I am all for Electric vehicles. The instant and constant torque, and the low maintenance. What we don’t think about 2-3% of vehicles being all electric it hasn’t really put a strain on the grid. When that number jumps to 40-50% or higher. Watch the price of electricity. It’s liable to cost you $40-$50 or more to charge you car. I can promise you when we have that many cars on the road charging. The electric companies are going to make there money on you charging. They will have to produce a lot more power, and when they do that. They will start charging more at the electric pump. Plus all these cars will cost a lot more to junk when they are done. The used car market will skyrocket for ICE cars. We have no idea what these cars will be like when they are 10-15 years old. A 2010 truck with 120,000 miles is a nice truck for the most part. What will a 10 year old 150,000 mile electric car be like? What will it cost to replace the batteries when it’s done and dispose of the old ones. What if I needs major repairs. I’m sure that won’t be cheap to fix, and you sure as hell aren’t doing it in your garage. So, while electric vehicles are great right now. I think they are a huge huge mistake.

Welcome to the internet. Armchair experts have been around forever.

...which apparently requires spotlighting for the OP's benefit.

You’re just filled with bad faith arguments that make absolutely no sense. You have a poor understanding of basic mechanical principles, and you’re stuck in a tribal position on an unproven engine for no apparent reason except internet points. This is clearly a waste of time, but for anyone who is looking for real information, they’ll find it.

Pretty easy for me. I needed the Jeep ASAP and there was a 2.0T available in the color I wanted with most of the options I built out as well.

Got it. Thanks.

I had two previous manual/v6 2dr softop wranglers. Never had a an issue with either one. They were truly the Jeep purest experience! I was nervous about the JL with the ground up redesign, new engine options, and all the tech, but I just couldn’t be Jeepless any longer.

This go round, ”we” wanted the 8spd automatic and 4drs, so that “we” could both drive it and haul the family around. I am just a fan of the pentastar engine, and eTorque was the only option for an auto. The eTorque engine, paired with the 8spd auto is surprisingly smooth and refined. If it hadn’t been mandatory, I probably wouldn’t have checked the box for eTorque, but it is a nice setup. You can hardly feel it come off and on at red lights and the mileage is much better than my previous JK’s. The 8yr/80k warranty on the hybrid parts also makes the $1500 up charge, a little easier to swallow.

I may be in the minority here, but I’ve been very happy with the eTorque v6.

Having owned a Tesla I can attest that they are indeed great - way superior to gasoline engines in how they deliver power. That said I strongly agree with you regarding the power grid. California already struggles with brownouts - will more EVs help that situation? I am less concerned about battery technology...that is improving rapidly. Ultimately I think solar will provide the best solution in places that are typically dry. The rest of us are screwed unless the government figures out that infrastructure must precede transformation to an EV focused transportation system. Unfortunately our politicians are dumb as stumps and the current majorityseems to lack a sense of reality.

Which I'm well aware of. I didn't start this thread for technical advice but mere curiosity.

 

[Caveman044]

This is all great feedback. I know we have had as many diesel responses, but it's good to have seen a few thoughts on those as well.

I find it interesting that the poll posted last week showed forum members own the 3.6 2:1 compared to the 2.0T. But in this thread the feedback between the two is about even if not in favor of the 2.0T.

I missed that poll, is it still open and if so can you post a link. I think my vote will balance things out a little more.. ?
