Hey guys, just wanted to bring this up to discussion since i'm sure someone else has heard this before as well and i wonder if anyone has actually tested it.

I heard from a guy who works for shell that the company produces the same octane gas across the board regardless of whats on the label. He said it's because the company can operate more efficiently by producing a single high octane fuel versus several lower octane levels... it's just too costly for them to refine three different fuels versus one. any truth to this or hear this before?

dont bother responding i wouldnt take the risk with my 10k motor etc etc... i'm not recommending it nor have i tried it. I just wonder if there is a way to test the theory or has anyone ever heard anything to back this up? discuss...

edit: guy i talked to works at one of their refineries... additionally, i am not responsible if some nut reads the thread title and throws 87 in his motor and kills it. read the thread.

 

interesting if its true, but i think somebody would have gotten them on false advertising by now

 

There better be a difference with all the money it costs over time..

 

thats great for people running 87

 

yea i dont think anyone will sue over gettig higher octane at the lower price for false advertising lol

 

Im pretty sure they make 2 octanes and mix them for mid grade. Many cars are designed/tuned for lower octane so they would suffer a performance and mileage loss if that were the case.

 

On EvoM someone did a test done on 10 differant gas companys on there oct rating.
I think Shell, Amaco/BP and chevron were at there advertised rating or higher.
I will try to find it.

 

you will not lose power running a higher octane...nor will you gain power higher octane allows you to run more timing and such with less chance of detonation

If the car were tuned to one octane fuel, and you change to a higher octane fuel, you may lose a bit of power, as the higher octane fuel has a slower burn rate.

All gasoline is taken from a low octane base (~80 octane or thereabouts) and mixed with toluene and other chemicals to produce the higher octane mixes.

 

thanks for clearing it up

You are wrong, end of story thanks for playing . Octane has nothing to do with increasing power NOR does it have anything to do with the rate of burn.

thats what i was thinking to ...good link beepy

 

theres no way. Everyone runnnig boost could tell if it wasnt 93 or 94

 

I drive a gas tanker and when we have to blend it ourselves or the meters do it.In Ohio the gas at the terminal starts out at 84-84.5 oct if you add Ethanol (10%) this will make it 87oct.If it is clear gas (no alc) 84 is mixed with 93 to make clear 87.Then the 89clear is the 65-35 split of the 84 and 93 and 93clear is just that.To make 89 w/eth you will take 87clear mix in 10%eth and on 93w/eth take 93clear with 87clear =91oct and then add 10%eth=93w/eth.You can bump up the octane rating with 10%alc on just about any nolead product by 2 points.As for BP/Amoco ultra 93 it is a 91oct with 10%eth.Some stations have the blender at the pump to make the stuff between 87and 93.Hope this helps.

i believe he is suggesting that the 87octane pump is still pumping 93-94....but i think we have pretty much killed the idea...

Maybe that is the reason for them selling everything off (stores,terminals,and refineries)east of the mississippi.They would be losing $.20 a gallon aleast on 87oct to match the the price on brand X across the street.

 

i wasnt saying it was true but thats how it came across to me...

 

good info though
