I live in the rural part of Texas and drive into the North Dallas area.

In the Dallas area they sell reformulated gasoline which supposedly has additives which keep the injection systems clean, thus causing cleaner burning engines to limit pollution.

I typically buy gasoline in the country without the additives. What is the best additive I can use on my 300E to clean the injectors. I do NOT need to clean the intake valves because I just put it together with a fresh valve job.

When using such additives in a high mileage engine, how much of the improvement comes from cleaning the intake valves and how much comes from cleaning the injectors?

If cleaning the injectors turns out to help, I may start using the reformulated gasoline in the city, rather than the standard gas in the country.

Thanks for any replies,
