Fuel price question

[wbwanzer]

In the last two weeks I noticed at the Rutter's gas station (regional chain here in Pa. that is Top Tier) that the 89 was actually a penny cheaper than the 87. Wondered why. Now today I stop at a different Rutter's to get gas for my S3 for which I usually use 93. The 89 and 93 were both $3.68 while the 87 was $3.69. I thought 'Great'. I'm catching a deal for some reason. Then I thought about it some more and decided that there probably was no 89 or 93 in their tanks and that it was all 87.

Would that be your guess as to the bargain prices? I've never seen this before.

I bet the 89 and 93 were cut with 10% Ethanol…

Probably aren't moving the 93 and marked it down to move the old fuel quickly, and most places only have tanks of 87 and 93, the pump blends a certain proportion of 87 to 93 to get 89.

If not even 15%

A station could get in trouble selling regular as premium, no matter what the price is. Why would they do it for no benefit?

I would think this is correct.

I have seen several rural chains which do that: the mid-grade is cheaper, but the difference is the 87 has no alcohol.
