Not the same old boring discussion this time.
I was out and about the other day and got caught out - running very low and with no Shell garage anywhere near (that I knew of) - I reluctantly spunked about 20 squids worth of BP Ultimate (97RON) into the tank. A few miles later, the exhaust gas warning light came on.
At the time, I didnt really twig the connection with the fuel. Anyway, the next day I found a Shell garage and splashed some Optimax in there - exhaust light still on for the remainder of that day and most of the next.
At the next fill-up I topped her off with Optimax, started the engine and within 5 minutes the light was off and hasnt come back on since.
Anyone had a similar experience??
