What Octane do you use?

chris4x4 your peak HP should be more with 43 throttle body spacers, maybe you should recalibrate your second turbo to dump directly into both your 3rd turbo and your supercharger via a y pipe. this is what i saw done on TTORA.COM. also vertor adjustable intakes and exhaust ports will minimize drag and allow for faster speeds with the drag of supersonic speeds. your biggest problem at that point will be the door-sill wind deflectors tend to melt at about 1350-1430 MPH so you might want to remove those before using all 17 million horses you got.

 

all this talk of jet fuel-- i dont get it-- i just use tap water cause ITS FREE!!!

 

I used the mid grade about 80% of the time.. at least once every two weeks the high grade to clean out the lines.

 

92 octane in Hawaii

 

Doesn't matter here. 87 or 91 and my junk still knocks around more then a battered spouse.

 

Clean out the lines? All gas does that.


Do you gas up every 3 days?

 

I always use premium. I can get 91 no ethonal all over the place around here. What I don't understand is why people think premium is better simply because it has a higher octane rating. can someone explain that to me?

 

The idea is that the higher the higher the octane rating the more steady and stable the burn is. Theoretically it's supposed to last longer too. However, given what I have ran into in my last two cars including this one. I would say the octane thing is a crock of shit.

 

Unfortunately I have to use 93 due to my engine knocking with lower grade gas...

 

Unless you a running a high compression 4, 89-91 octane has zero benefit on a 4. I have actually heard through the grapevine that it can actually hurt your gas mileage.

 

87 on all our vehicles.

 

No, that was RUST that caused that! LOL

 

This is right. longs I don't go more than 65 mph.. I don't drive like a old fart.
its cleans the nozzles of the injectors..

 

The cheapest...around here it's usually about 87

 

Non ethanol 95% of the time and if traveling I use premium. Have several non ethanol station around me

 

to get 91 octane refinery has to make another pass, that means fuel is cleaner. On the side note 91 allows engine to adjust and run leaner under the load with out knocking. That means you get to stay on high gear longer and on lower rpms. So if you drive normally you will get fuel savings. Truck will hit 20+ MPG on V6.
However if you live in cold climate high octane is not best choice so once temperature drops below 50F its time to start switching to lower octane.

 

wut?

 

eh? run another pass to make it cleaner????? does this fella BlueT knows what he talking about??? I used to work in the oil gas field.. so I am calling it BS.

 

I swear mine hates 87, i run that 89 octane sex juice all day.

 

I use the type that gets me to work,normally 87, I reserve the good stuff for my older cars that used leaded gas.
