In the Chicago Tribune, Motormouth column, it stated that instead of using additives, "5 fill ups using 93-octane will clean out injectors, valves and combustion chambers". Any comments good vrs bad on this?
It will only clean out your wallet.
Hmm, I distinctly remember a few years ago that one major retailer advertised that the 'midrange' and the 'premium' both had more detergents and solvents than 'regular'.
Are you saying they lied? Not that I'd trust a gasoline company, but I wouldn't expect them to lie where they could be caught.
I'm aware of at least SOME of the fed requirements, but a lot of that is 'clean air' BS, not detergent as such. Last March, when there was a small shortage, I heard there were 38 separate formulations. And most of those were seasonal. No wonder gas is so expensive!
Depends, What do you need to be tested for?
