When I had my saturn, I could leave a blue cloud of smoke the whole distance of an on ramp the 401. And it passed the etest with flying colours! The guy said the etest cant see oil burning but the 02 could and would fail it. Mine never failed and I burned thru 2 litres a week.

He also said they look under the hood to ssee if its a stock engine, ifnot they run it as a hotrod.
