So I was peaking under the hood the other day and noticed this tag on the hood.

(key sentence here is "Not for sale in states with California Emissions standards")




And this got me thinking...

Are there different versions of the JK engine sold in states with california emission standards, and would this explain some of the wild differences between the gas millage people are seeing in different areas of the country. Could this be the answer to why some people think the engine is terrible and others can live with it? Or why people experience wild performance increases vs nothing at all?

I have not seen a discussion like this before on this forum.


I was wondering if anybody had any input?

 

CA cars these days usually do not have lower power/mileage. They have different style/add on emissions setups. I do not believe there is a tune or internal engine change.

 

Yet another reason to never go back to California

 

I think the fuel blend and altitude in a particular area are a bigger factor. There are literally hundreds of different fuel blends used throughout the country driven by state and municipality laws for clean air. Just one more reason why fuel costs so friggin much.

 

That's 100% true, if they could all get together and come up with a national blend to be sold everywhere the price would drop considerably.
