(14:57:56) themattreid: I'd run 85 if they had it here - they have 85 in Co
(14:58:10) whitepony65: what does Ca have?
(14:58:12) themattreid: 87
(14:58:52) themattreid: maybe worse mpg out of 87 but here's the math... let's say 2.99/g for 87 , 3.19/g for 91
(14:59:10) themattreid: so my tank to fill is usually 25 gallons
(15:00:00) themattreid: so 87 at 15mpg is: 375 miles per tank at $74.75 a tank
(15:00:13) themattreid: let's say 91 gives you 2 mpg better?
(15:00:33) whitepony65: yeah
(15:01:05) themattreid: 425 miles per tank at $79.75 a tank
(15:01:22) whitepony65: $4 = 50 miles
(15:01:26) whitepony65: worth it
(15:01:37) themattreid: .18 / mile for 91
(15:02:00) themattreid: .19 / mile for 87
(15:02:10) themattreid: interesting, I may try 91
(15:02:43) themattreid: although in my manual they say 89 is better for the engine than 91 - but that's for my truck, not sure what they say about your engine
(15:02:57) themattreid: so I'll fill up 89 next time and see what I get
