I notice that there was an old topic around this subject, but just seen that biofuel is going to happen in a big way now in the UK (and europe?) to up the content to nearly 15% which - its suggested - is a BIG no no to old mercs and many other older cars.
One thought was that the higher octain (98/super unleaded/ ultimate etc) was ok?
What is the latest thoughts now that bio fuel is here to stay - and get even higher levels added.
