I just don't get why every new JK owner braggs about the 3.6. Its an aluminum engine just like the Cadillac North Star Engine. It will leak when it will over heat.

The 3.8 is a proven engine.

On any 4 x 4 gearing both engines are not that good. I had the 3.8 on a grand caravan and it moved alot better.

And the 3.8 doesn't leak or burn oil? How about the 40% increase in horsepower over the. 3.8. That is not insignificant along with better gas mileage. I dont thjnk the 3.8 would tow my toyhauler nearly as well as the 3.6. I now have 32,000 miles on my 2012 JKU and couldn't be happier with my purchase (except for the stupid clock that loses 5 minutes every few weeks. I'll have to take that in for the TSB someday).

0-60 in 7-7.5 seconds isn't really hideously slow for a 4x4 in my opinion....

probably not as it is the universal sign that you are broke down lol.

Sounds like 3.6 envy to me.

The old slant 6 was a proven engine too, want one of those? Actually if it'd fit, that wouldn't be a bad idea!

3.6 engines don't need a symbol. They have a sound!!!! Tick tick tick tick tick tick tick tick tick tick

Just sayin

Hp doesn't matter tq does. Thats why semis have 350-400 hp but 1500 tq. And as far as the 4.0l it made its power at 2000-3000 rpm not at 5000-6000 like our pentastar does. When I had my old tjs my rubi who easily roast em with 35's and if I launched it I could carry front passenger tire a foot off the ground for 30-40 feet. Never done that with my pentastar
