I just returned from testing the aprilia on its CO2 emissions in a friendly local garage before I go to the MOT next week.With a little adjustment as we tested, it is now producing a miserly 1.5 % emission and the limit to be achieved was 3% or under.This seems rather good for a 61 year old car.How does this compare with moderns , any ideas ?.
It clearly would suggest I have to drive as much as possible to help save the planet....

An Aprilia, in cpmmon with all PVT cars, does not need to undergo emissions testing.  However, an impressive result suggesting even that your mixture is a little lean.

I presume what they were measuring was your CO (carbon monoxide) rather than CO2 - most of your exhaust gases with a modern or an old car would be CO2 or water vapour.  On a modern, CO, NOX (oxides of nitrogen) and hydrocarbon traces (unburnt fuel) should be in fractions of a percent.  However, for an old motor CO readings at the level you suggest, and for any pre cat car, are pretty good.

how right you are..in my elation at the better than expected results I started typing before engaging brain...

strangely, in the inverse "lewisiaan" universe I patrol I seemed to write this only a few minutes ago but as clearly evidenced below it was nearly a year ago of your earthly time...Maybe I should have mentioned Carbon 14 instead....

in either case I have strived to use the car more to save the planet as described...

Well, we old car types are often accused of living in a time warp.
