A lot of diesels emit black smoke whether you’re trying to or not especially if they are older or have motor work. Also a lot of people on this thread like to talk about penises when they don’t understand?

Does anyone at Jalopnik have any hands on experience with a high hp diesel truck? Most of this is misinformation and generalization. A lot of older diesels or diesels with motor work done will emit black smoke. A bad injector or a clogged air filter even makes it do that. Not everyone rolling coal is trying to do so

Hey will, I know how you feel about the MAVTV 500 what is indycar doing about this race in regards to driver safety? On a lighter note I'll be at Indianapolis this year and I'll be pulling for you!
