Default Should I run e85

2006 Silverado 5.3 (L59)

All the signs are there that my truck is cable of running e85. But for some reason I keep having second thoughts of feeling up e85 when I'm at the pump. Can somebody ease my Conscience. I guess I'm just worried about if the fuel system transitions smoothly between 87 and e85

The L59 is flex fuel capable. The transition should be seamless.

Can you? Yes, you can.

Should you? Doubtful. E85 does have some advantages. But you'll use about 20-25% more of it. In Colorado gas is $2.07, and E-85 is $2.00. It would cost a lot more to run e-85. But, if it's hot and muggy and you're hauling a heavy load, the e-85 will run cooler and help prevent detonation.

Your call, though.

Down here in corn country (Nebraska) e85 is 1.69 at the station a mile away a town over it is 1.49 but it tested out to e78 while the closer one was e90. Normal gas prices are 2.09. I will be running e85 full time when I get my vette back but I will be at 14:1 cr. At a performance view I picked up 22rwhp in my Z06 so I was very happy uping the cr will net me even more gains.
