Turned in a smoker today. It was a late model Mazda coupe of some sort that couldn't have been more than 1-2 years old and was smoking like a freight train.
And it wasn't just oil smoke either...they were noxious, eye-burning fumes a zillion times worse than anything I've smelled/seen out of any diesel.
Here's the link if you want to do the same. ( in Texas).
