I’d really like to see some scientific evidence of that.

Can you direct me to a web site which will corroborate you assertion?

Thanks.

I take it you mean the fact that gasoline is dirty. Of course, all of the additives from ethyl and lead to MTBE and ethanol, are or were added for the basic purpose of cleaning up the dirty combustion of gasoline and increasing the octane level.

Ethanol has the added advantage of cleaning up water and dirt in the fuel tank and lines.

There are many fuel line and injector cleaning gasoline additives available to buy in auto parts stores that are compounds of alcohol. Nearly all proprietary products that advertise their ability to clean up water are alcohol compounds.

You mention buying unleaded gasoline. When they started advertising lead free gasoline, there was a huge backlash of people that said unleaded gasoline would destroy their engines. It was supposed to be particularly lethal to lawn mowers and chain saws.

Most websites speak more to increasing octane than cleaning up dirty gasoline combustion.

Here Are a couple of URLs, I hope you find them helpful.

Just stick your finger in your cold exhaust pipe and see the gunk that is in there.

I dont know any professional that questions gasoline being dirty. That is like snow being white and the sky being blue. Hundreds of billions of dollars have been spent trying to fix the problem
