What do you feed you 991.2?
So down here we can get 93 with ethanol or 87 at some place 91 pure with no ethanol.
What would be a better option?
i thought that 91 pure would be better than 93 with.
But how about 87 or 89 pure vs 93 with?
In my bikes it’s always pure, even if it’s 87.
Would that be the same on our 991.2?

Buy the highest octane (93) you can find from a busy national chain. Don't worry about 10 ethanol. Octane trumps ethanol.

Thanks,
so higher rather than pure is the call so far.
After opening a few bike engines, the decision is pure any day after seeing that what the ethanol residue.

What is 93 octane? What is not ethanol gas?? Here is the Krappy Left wing Kalifornia we have Krappy Kalifornia gasoline with nothing over 91 octane standard and it is all Krappy gasohol.... not to mention Krappy blends for different times of the year even if we do not see the seasons change in Krappy Kalifornia. Did I mention that we also have Krappy Kalifornia gas taxes and Krappy Kalifornia outrageous DMV fees?

Ethanol does burn a bit hotter and will cause your catalytic converter to go before its time. Shell and Chevron, work well.
In fact my wife was putting Costco gas in my X5M and then I noticed the check engine light came on. I cleared the code
with the reader and back to chevron and the light hasn't come back on. Just one data point

My informed opinion (I work in O&G, but not on the refining/retail side) - you want the brand with the most control over their supply chain from refinery feedstock to pump. Only two brands that I'm aware of have common QC standards across the entire supply pipeline nationwide so that what you use week-to-week has the highest chance of being identical in composition...
As a general rule:
If not in California and in L48...
(1) Shell 93
(2) Chevron 93
(3) Find a Shell or Chevron.
(4) BP is generally good (no sub-contracted supply) in the North and East
(5) Texaco is generally good (no sub-contracted supply) in the South and East
(6) Exxon is generally good (no sub-contracted supply) in most of the country
In Alaska
(1) ConocoPhillips
(2) BP (Arco)
Hawaii
(1) I think all gas in Hawaii is contract refined (someone correct me if I'm wrong)
If in California...
(1) Chevron 91
(2) Shell 91
(3) Valero 91 (Variable Refinery-to-Pump QC)
Price-wise you are SoL because Chevron and Andeavor control most of the (very limited) refining capacity - and CA blends are generally only used there.
From what I've read and seen in some SPE presentations - Shell, Chevron, Exxon have the most advanced detergent / additive packages as of right now (in that order) - BP, CoP/Phillips66, Marathon are next - the contract products are 3rd and generally all meet Top Tier.
In a pinch - any Top-Tier formulation will be fine - but a lot of "slack" is built into the quality standards to allow for variance in refined products.
cheers!

I guess the hunt for pure is no longer needed. That would make it much easier for me to find a Shell bs Pure.
Btw, there is a great App for pure gas I use.
