Cu2 rattle

[SRVTIR]

So the dealer mechanic is telling me the rattle when under load is from e10 fuel and nothing else??? Has anyone heard of this occurring? The car when under load makes what sounds like a exhaust leak or rattle ???

Its called Pinging....not enough octane in your engines combustion

So it's normal? Ok

Yes if ur a baller and want to buy new engine!




NO - it aint normally and should be checked immediately. If ur motor is pinging/knocking then expected a CEL code and car will go into limbo mode!

Get it checked m8

Use up the remaining e10 asap without straining the engine or even siphon it out and fill with 98 and then can go back to 95 if you so wish

If you need explanation for the sound and cause look up combustion detonation or knocking

E10 fuel tends to be 91 octane, whereas the CU2 requires 95 octane or higher. If your tank is half full, just top it up with 98 octane. That should bring the average octane rating of the petrol in your tank up.
