Lucas is really just oil. No detergents.
Gumout, STP, Techron, Prestone, Vavoline all contain detergents. There are two types of detergents that will work. PIB detergents work at lower concentrations but only clean the front end (fuel injectors, intake valves, etc). PEA detergents will clean the combustion chamber area as well as the other areas, but require higher levels of detergent. I believe that Techron, STP Complete, and Gumout Regaine complete all use the PEA detergent. If you are only going to add a fuel cleaner at oil changes, I would choose one of these. There are several gasoline companies that put in good levels of detergent. They meet the top teir gasoline standard. You can look them up online. Their gas will keep your injectors cleaner longer.
