I went to gas up at Unocal 76 as I am running 1/4 tank left and when I got there the highest was 91? The guy said I could use 91 that it is the same thing only cleaner. Is that true? I just left and went home.

Please help.

 

It is not the same as 92 or 93 or it would have that number. Your car will run on it but may have reduced performance. It is not the ideal fuel.. go to another station.

 

The only other Unocal offered was 100 octane. but it was almost 5 bucks

 

I know that here in Colorado, 91 seems to be the highest. It is due to the high altitude.

 

I believe the thread is in off-topic, but there is a memo going around from Tosco (unocal/76) saying that all California premium will be going to 91 (vs. 92) starting August 1st. Something to do with ensuring a better supply of premium gas.

I'll be calling the customer service line on Monday to verify, but it wouldn't surprise me a bit if true.

What really pisses me off is that you just know the pricing won't go down a bit relative to the cheaper blends. Never mind that it is cheaper to crack and mix a 91 octane vs. 92. And the whole demand pricing is b.s. too. I went to Phoenix recently, where there isn't a refinery for 500 miles, and premium unleaded was about $1.70-1.80/gallon. Out here in L.A. I pay $2.10 on average and there are three refineries within 10-15 miles of my residence.

I'm ready to organize a protest if the gas companies unilaterally change octane ratings. I'd rather pay $0.10/gal more than get 91. Because on a 12 gallon fill up with 91, to raise my octane by 1 point I'd need to add about 1.5 gallons of 100 octane. At $4.79/gallon, that means I'm paying an additional $4.05/fillup. That comes out to a $0.35/gal premium. Simply ridiculous.
