Exaust Smell?

I imagine our noses are very sensitive to even minute amounts of that compound - amounts that are below any regulated limit.

Thanks for keeping me humble and reminding me I don't know everything, Lars!

Oh Jack, I am not trying to humble you. I just had a flash back to the early 90's when they started to make diesel "dryer". They took out a lot more of the lubrication of the fuel by doing this and a lot of those motors fell prone to failure.

Does sulfur create the same compounds when it burns regardless if it is spark ignition(gas) or compression ignition(diesel)?
