[QUOTE="astroboy, post: 350712, member: 4527"] Check your fuel cap for the RON spec. This RON number is the stabilizer number. The higher the number, the more stable preventing premature ignition due to compression rather than waiting for spark plugs to ignite. They call it "knocking". Later generation of engine are mostly higher in compression because more power, more efficient combustion. That's why they need higher RON fuel to avoid premature combustion or knocking. Later generation of BMW has "knock" sensor but I dunno how it works to reduce "knocking". [/QUOTE]
