Is unleaded fuel required in China? I don't know. If the Chinese are still using leaded fuel, you might very well be correct. I remember reading somewhere that the Italian company, Piaggio, designed the NC250 engine. I suspect the Italians designed the engine for use with unleaded fuel.
I'm hoping my experience with this problem is a rare exception. However, I felt an obligation to warn others who might be experiencing the same problem.

One more question Spud. Lead did many things including lube the valve seats.....which is why the earlier cars were having trouble without it.
Now....I've never been one to believe in "Miracle in a Can", but I've been running that Lucas fuel treatment that CSC recommended for break in.....just because they recommended it for break-in.
Do you think this stuff really does any good and also, have you been running it in your RX3?
Here's a quote from the Lucas website.
"Lucas Fuel Treatment should definitely be used in vehicles that require leaded fuel because it actually replaces the benefits of lead in gasoline...."
Makes ya wonder.
