Very useful video, thanks.

I’ve seen people over here in Louisiana driving with blue smoke coming from their exhaust. Smells awful and I end up turning on the recirculation control in my car. It’s a pet peeve when people neglect their vehicles maintenance.

Good morning from Greece! Congratulations for your video. I have Hyundai tucson 08' 2000cc turbo diesel. The best oil is 15w40 , 10w40 or 5w40 the engine have overhaul, 0 miles.

Super informative. If blue smoke comes just upon ignition, and continues with pressing gas but only u til engine warms up - what’s the best guess? Piston rings or turbo charger? Turbo diesel engine

Is it worth buying a engine with blue smoke?
