On the subject of " Euro ", I can tell you this.
I frequently visit Germany and, to my amazement, as little as 10 years ago, they were still able to buy leaded gasoline. We have not been able to do so in Canada for about 20 years.
At the same time, anybody with an older car ( 1980's ), qualified for a government taxrebate if they retro-fitted their cars with catalytic converters and hardened valveseats & valves.
Okay, enough preaching, time to move on.
