I own a 2014 fusion se with 1.5 ecboost engine. It now has 10578 miles and has been great so far. Found out using pure gas compared to any unleaded fuel with some ethanol in it increases fuel economy by 2 to 3 mpg.
Recently I've noticed while turning left, at lower speeds, there is a distinct piston type knock in the engine. Anyone else notice thus? I have apt. At dealer next week. Thanks for any input you might have.

UPDATE. Loud knocking when turning coming from engine area on my 2014 fusion 1.5 ecoboost engine is from a mechanical fuel pump. OMG

According to Dealer there is a fuel pump on top of engine which causes the noise. My question is why does it only happen when turning? Sure sounds like piston slap to me.
