In India, we have a limit of 3% of volume being CO(whatever). Although most cars would clear that test easily, what is a good reading.

Say till one year back All my PUCs used to read 0.02%. Now recently all show 0.4% to 1%.

I have 3 cars, all Maruti, and all have shown the same trend.

the way I see it 0.02 to 0.4 is a 20 times increase!!!

So just wanted to know, what do you people get in your PUC. And any idea whats a good %.
