93 octane w/ethanol or 91 without

[krayzie]

Crickets on ethanol-free 91 here so myth debunked! It just sounds louder than DI HPFPs on other cars, they all make the same cricket sound.

Some people have reported success in getting rid of crickets by using either an upper cylinder lubricant or ashless two-cycle oil as a fuel additive. Their thinking is that the extra lubrication in the fuel smooths away the cricket. I'm about to try Marvel Mystery Oil myself. We'll see how it goes.

I've noticed a difference in the level of noise between fill-ups from different gas stations, but the sample size is far too small to make any significant claims. I have found a station that has consistently kept noise low. If I need to buy gas elsewhere, the noise usually comes back by the time I've gotten 1/16 through the tank. e10 93 always used.
