Hi,
heres an example of what happens when using poor fuel..................
Can you see it ??
You can now, that’s what’s called a ring land failure and is due to detonation caused by poor quality fuel, eventually the broken bit rattles around, wearing the bore with debris until the engine is beyond repair, signs of this already show on the piston skirt.
The images shown are a piston from a 2.5 STI hatch that the owner admitted to running on 95 and sometimes 97 octane fuel, food for thought ......
cheers
