30 cents more in the tax free army base, and 45+ cents more everywhere else here, and good luck trying to stay under boost in NYC. You won't even make it to the next light accelerating that slow.

That would make sense if you lived in the borough of Manhattan, but those that drive usually live just outside of it. Nobody wants to take public transportation with the rest of the non car owning peasants.Used to work in NYC. Never understood why anyone drove. I walked faster. Lol
Higher compression benefits from higher octane, as well as vehicles with advanced timing. I have to run 93 in my Mustang or risk the consequences due to the tune it is running.About the fuel āupgradesā...
A higher octane will resist āexplodingā when getting compressed in your cilinders a bit better then a lower octane. You want it to explode at the perfect time, initiated by your timing and spark plug.
If your engine does not compress very much, nothing (bad) happens with either fuel. The fuel air mixture does not explode prior to your sparks timing... perfect.
If you have a high compression type engine (either by design or through turbo or compressor install) there could be an issue with low octane fuel igniting prior to the perfect moment, (when your piston is still traveling āupā compressing the fuel air mixture). So compression is igniting the fuel, not the spark (thatās how diesel engines work, diesel octane is low 40). So thatās when a higher octane fuel resist ignition during compression and waits for the spark so to say.
Putting a high octane fuel in a lower compression engine does absolutely nothing. Nothing will run better or happen differently.
Itās like spraying your mufler wet while your driving in the summer to keep it cool . It wasnāt a problem to begin with. The preventive action is not going to make anything better.
Putting high octane gas (premium gas) in an engine that does not require is, is a waste of money.
I hope this helps to save some people some $ to buy extra upgrades for their new JL
I think we are in agreement here. So If your compression requires higher octane I would say a low octane is going to give bad results. High octane is not going to give ābetterā results then expected from the engine. Just better then an incorrect low octane fuel for that engine. In other words: getting an even higher octane fuel will not make it āeven betterā. You run the engine with the fuel it requires. Higher is a waste of money, lower will give bad results.Higher compression benefits from higher octane, as well as vehicles with advanced timing.

Pentastar Jeeps require regular, the 2.0 requires 91 (unless you are willing to risk it). We do agree that higher octane has no performance benefit in and of itself, but allows more timing and higher compression ratios that produce more power, without detonation/preignition.I think we are in agreement here.

Agreed.Here is where my "BS meter" pegs the scale! All this hubbub about the 2.0 having better fuel economy is facade and marketing BS because economically the TCO cost of the 2.0 will never pencil. In our area premium gas is consistently 70 to 80 cents MORE expensive than regular. Take the extra cost of the engine plus the need for premium fuel vs the V6 and you will never have an economic return on this investment.
