this seams like another cc thread lol. I just put in a new o2. but thank you every thats posted its been fun. ohh and thank you steven hawking for the vocals. but ive got other stuff to do. If anyone else has any other combinations brands parts they have had luck with let us know. But I dont think Ill bother with this thread again. To much bickering. But you never know. thanks
"• Always follow the auto manufacturer’s octane recommendations in your owner’s manual.
• High octane gasoline improves mileage.
In general, if your car is designed to run on 87 octane gasoline, high octane gasoline will not improve
mileage. If switching to high octane gasoline does improve mileage, you might find that your engine, or its
control systems, need repair.
• High octane gasoline gives quicker starting.
No, it doesn’t.
• High octane gasoline increases power.
If your car is designed to run on 87 octane gasoline, you shouldn’t notice any more power on high octane
gasoline. Again, if it does make a noticeable difference, your engine, or the engine’s electronic control
systems, may need repair.
• High octane gasoline has been refined more – it is just a better product.
Additional refining steps are used to increase the octane; however, these additional steps do not necessarily
make the gasoline a “better” product for all engines. They just yield a different blend of hydrocarbons that
burn more slowly. The additional steps also increase the price."
"What else influences my car’s octane
Temperature: Hotter air and engine coolant
increase your octane requirements.
Altitude: Higher altitudes decrease your octane
Humidity: Drier air increases your octane
"Effects of Air Pressure
Altitude decreases an engine’s octane requirements because of the change in air pressure. The higher elevations have a lower level of air pressure, which means an engine needs less octane to properly fire due to the lower ambient pressure. In certain states, such as Colorado where the altitude is generally above 5,000 feet in the mountain regions, 85 octane gasoline is sold, while in lower elevations 87 octane is the lowest sold.
i have found this very entertaining
and just so you know,
Gas at gas stations is like orange juice
its all the same and the only difference in flavor is the packet they dump in it
95% of the fuel in different gas stations around you comes from the SAME fuel truck.
The only difference is the additive (octane,detergents,stabilizer..etc) he dumps in it after filling the underground tanks

I agree that gasoline quality and composition depends upon where you buy it. I've had bad experiences before with getting water in gas, and the 4.0 stumbles. It'll manage with really crappy gas, but it'll run like crap. Then there are places with 100% gasoline with no ethanol. This will perform a whole lot better. Our engines weren't designed to run on corn alcohol. Using higher octane often just results in getting more actual gasoline, but that still depends on where you go to buy it. I've had better experience with 85 octane regular that's 100 gasoline I bought in Colorado, even when back at 3900 ft where I live; than when I run high octane, which is a waste for the 4.0. But plus usually does offer a slight improvement in performance. It's called real world experience. Whether it's got less junk in it and more gas is why this is, I don't know. I'm not a chemist. I just know it works. Not all gas is the same, I reiterate. It really does depend. It's like saying water is the same wherever you go. Then go get water in Ohio. I'm betting it'll taste different than what you're used to, unless you live in Ohio. There are just too many variables to make a blanket statement. Then there's the evident bias. Everyone has their opinions, and they're, all combined, worth less than a gallon of gas. That'll be $4.00 please.
So replaced everything mopar and champion plugs and heres my review. slowwer starts, less power on demand, does have a smoother idle though. engine doesnt shake as much. so better for the motor. did notice a drop in how many mpg I get. So all together champion mopar has a nice smooth soft idle. Although less performance, gas milage, and slower starts. Is better than bosch +4. with the rougher idle the rough shakeing. just runs more rugged. with more power on demand, fast starts , and better mpg. With the high miles I have now Im going with the smoother idle as I beleive that running the engine with the bosch +4 ignition system even though better performace will wear things out alot faster. running an engine with high mile more rugged/rough cant end well. so at 280,000 something im switching back to mopar/champion. for the smoother engine wear.
say im wrong you know everything I know I know bla bla bla stick in the *** I know youve done everything and know it all. I still will never run any of my rigs on regular. enless I ever buy a four or six cylinder. I think ive seen an ad that says you can fertilize your grass with used motor oil, you should try that too. Ill stick to running 93 octane. changing my oil every 3500 miles and doing all my tune ups on time everytime. to say theres no differnce between regular and 93 octane you would have to be retarded. go to a gas station try it. performance mods can give you performance but it is always at a cost. and yes removeing your a/c and fan can give you more horse power.
