100 octane in SoCal

[Plxdjake89]

Has anybody messed around with this before?

I pretty much want to know how to achieve 93 octane by mixing 100 and 91

8 gallons 91 + 3 gallons 100 seems to be a good mix according to that chart.

Chart seems legit but what are you gonna be running it in?

So if 91 is $4 and 100 is $8, you're looking at a gas bill of, roughly, $57. If you put in 91 only though, it comes out to $44. $13 difference. Not bad if you live near a 76 station that sells 100 octane.

$13 x 52 = $676

That's roughly the extra cost a year, if you put in 11 gallons on a weekly basis.

I'd like to put it in the frs, but to be honest I don't know if it's safe. I pretty much just wanted input to see if it was possible to blend the 2 to make 93.

There's actually a couple of gas stations with racing fuel if anybody else is interested in doing the same. I'm hoping this clears up the crickets I have chirping every time I go for a drive. Here's the link to the list of stations in so cal

The blend is possible but you'll get about zero gains. A random search here or any other automotive forum or google will tell you race gas in a stock car is going to be just about useless. Save your money.
