Some sort of knocking...

[Zed 71]

On the next tank just try and use Teir 1 87 octane gas. No need for higher octane on a stock truck and it will have cleaning agents also.

Thatʻs probably why... Iʻve been using a local company and maybe they are not teir 1... Iʻll look into it!!!

Hereʻs an update on my Hoe... I have been running experiments with the different brands over here in Hawaiʻi so Iʻve come to find out that its not the different brands or octanes but rather my HOE!!! No matter what brand/octane I used it still had that machine gun-like knocking sound when I accelerate slightly at low RPMS... So I have decided that I am going to take it in to my dealer...

But on a lighter note... Happy Thanksgiving!!!

i could not find any bulletins on your knocking noise other then possible incorrect oil filter or install.
