I wonder how much fuel they gathered for the test. When you buy fuel at a pump with one nozzle that dispenses two or three octanes, everything left in the line from the prior purchase is what you will get until the pump starts sucking your choice. Basically, you'll get a hose length of low octane before getting your high octane. If the test conducted by Good Morning America only comprised 3-5 gallons, it is very concievable that the octane value in the test sample was lower than advertised. Without knowing how the test was conducted, the test could be misleading.

As to octane, it is only necessary to run a level that keeps the engine from pre-detonating (pinging). If your car does not suffer from pre-detonation at 91 octane, it is simply a waste of money to spend for a higher rating. Also, higher octane will do little/nothing for HP, torque, or engine performance.

The inspection showed that the "93" they were selling people was actually just "91.5". I watched it probably 2 months ago. It was owned by an Arab/Indian family in another state out west I believe.

RaceTrac's 93 passed the inspection.

I try to only go to the newest stations too in hopes of having "cleaner" fuel since everything is new.

Heres a link to a test done a few years ago but I don't think it specifically names stations.

Unfortunately, the neutered 91 octane we enjoy in CA. I have gone to the VP Racing distributor down the road from my house on occasion to throw in a couple gallons of race gas once in a while but that is about it.

I usually use Exxon here in MD. The Sunoco by my house has failed their inspection multiple times for not using gas with the advertised octane rating.

Shell

Whatever my neighbor's John Deer rider has in it!:bowrofl:

Mobil 93 or Shell 93

Ron 95 octane is the normal gas in Malaysia..my car drinks Shell V Power Ron 97 everyday..price @ RM 3.1/litre..about a dollar.

you can read more at

Top Tier Gasoline

It also lists the brands that carry top tier.

Greg,

Thanks for this info. I never knew about this.

I knew there was a reason I never used 7-11 gas :P

93 octane for those that have it available. otherwise 91 will suffice

:iagree:

I wonder about the so called top tier gas companies. It seems they want you to spend more money i really don't think it really helps. Chevron, 76, shell are expensive. What is wrong using 91octane arco, sams, hell safeway grocer store chain gas and raley's grocery store chain gas?

its the additives i believe

That is correct. All gas is the same coming out of the pipeline the only difference is the additives put in by the retailer
