Techron is still the best fuel cleaner IMO. It is proven safe and effective, yet is readily available and inexpensive. Chevron's gas with Techron was the only gas that did not need revision for the Top Tier IIRC. Most people will tell you Chevron makes the best gas and fuel cleaner, I concur.

This is setting the new standard for gas.
