3.6 or 2.0

[kah.mun.rah]

Because its broken. The 2.0 just sounds like a tractor.

Yes, yes it does.

so youre saying it sounds like a Viper

2.0t cause I like knowing I have a small tornado under the hood and not an engine that eats itself because jeep is too lazy to actually fix it

The problem for me when choosing was there just isn't enough proven reliability for the 2.0 yet. It still falls under the newish/proving itself category. Unlike at the 3.6 that has 15 million produced and proven.
Not saying the 2.0 won't prove itself but it's still in the unknown phase. And with all these manufactures having turbo motor troubles, I just don't trust stelantis enough to have figured it out. And that's why they had to keep the 3.6 around because even they don't know if this motor is going to make it and they knew a lot of people wouldn't buy a jeep if that was the only option.. (my .02 of course)

I've actually been seeing more 2.0 complaints recently. Could be a fluke.

Only time will tell when we start seeing or not seeing more 2.0s at the 150k-200k mark.

Most of the complaints I see are from people who don’t do any research before buying and could’ve easily googled any of their complaints to see that most of them are just how the 2.0t is. The Facebook JL page is horrible for that, so bad I actually had to post a video nicely calling them idiots for not researching before buying a 30k+ dollar vehicle only to complain lol. These people can’t even change their oil on time let alone use the correct oil so yeah lol

Of the two I'd go with the v6 since it has no direct injection, and because the manuals state that 1) the V6 requires 87 octane to attain full performance and derives no performance benefit from higher octane, and 2) the 2.0 manual states that it will run on 87, but for best performance and mileage it specifies 91 octane.

That said, I own a 392 Rubicon with shite mileage, and I've owned a 2.0 turbo Rubicon. The 2.0 is just a more complex engine due to it's turbo, intercooler loop, direct injection, and the associated high pressure direct injection pump. The V6 is relatively low tech, as is the 392.

The 392 has 10.9:1 compression, the V6 has 11.3:1. and the 2.0t has 10.0:1, but the turbo increases pressure which increases the octane requirement.

Also for the engine that makes better power so you can drive away from the v6 manual luddites as they sit there praying this isnt the time their jeep burns to the ground.

The 392, of course silly!

Great analysis, makes sense. Definitely want one that works optimally on 87. I'm never going to put more expensive gas in it.

if you think the v6 runs optimally on 87 I have some bad news…

Having had two 3.6 Gladiators that Stellantis bought back I’m not a fan. The 2.0 in my JLUR has been good but I’ll reserve judgement for now.

The one that isn't the Fiat agricultural engine with a turbo.

It won't make much difference to most but I live in the hottest city in USA (according to the weather channel list of hottest populated cities with most days over 110 degrees). I see 120 and higher every year in the shade on my patio and have seen 127 a few times.

Now we all know blown engines (turbo/super charged) build excessive heat and will coke oil quickly in those conditions. Based on that plus lack of direct injection I chose the 3.6. It's too early to tell if I made good choice but being 74 y/o I will prolly not out live either engine anyway!!

Over 16 million Pentastars built since 2010, 93% are 3.6, the rest are 3.2. It's been the #1 engine in Canada for 6 years. Most valvetrain & cylinder head failures were in the 2011-2013 years. Failure rates of Pentastar engines are exactly in-line with the average failure rate of all American made car engines...1-3%.

Yes, the needle bearings in the rockers are delicate, but the vast majority survive past 150,000 miles. It's possible to avoid problems with proper maintenance, reduced coolant temps, and possibly higher viscosity oil (Note: the recommended oil weight of Pentastars delivered to most countries outside of the USA is 5W-30. Also note the vast majority of USA engines live a long life on 0W-20, even in hot climates.) Note: most "synthetic" oils are based on modified dino oil, a lawsuit allows them to call their oil synthetic. Use a REAL synthetic oil, Redline, Amzoil & some Liqui-Moly. They use true PAO & ester bases...ester is known to cling to metal.

More points: that "ticking sound" frequently heard on startup could very well be a lifter still pumping up. Watch your oil temp...it takes 8 miles to get the oil up to operating temp, unlike coolant, which is at operating temp usually under 2 miles. High coolant temps are great for emissions but bad for engines. Adding the excellent RPM Extreme fan controller will initially turn the fan on at 195°, instead of the 215-230°, depending on other conditions.
