Generally the heirarchy goes from "gas treatment" to "FI cleaners" to "fuel system cleaners," weakest to strongest. Products in the latter category almost always claim to be able to be able to remove combustion chamber deposits, which is my initial screening criteria in the store. I used the STP fuel system cleaner when it was introduced in the American market and remember asking STP for, and receiving a very convincing brochure from them that depicted before/after scenarios.DavidS said:What are the practical differences between STP Injector Cleaner and STP Complete System Cleaner?
Which is the optimal way of deploying it: with a small volume of petrol, or with a full tank?
Here's a link to the Techron site and their "Chevron Professional 3-Step Fuel System Cleaner featuring TECHRON." Well worth a read if this thread interests you.6spd said:I'm surprised no one has brought up Techron yet.
David- The issue with sooting on aircraft is a two part problem. First off they are not cleaned often, and second there is a limited exhaust duct for soot to catch on. But I do agree, in terms of aviation fuel (of ANY type) and cars, it doesnt mix at all. Jet-A might run in a diesel engine, but putting it in a normal car is bad bad bad.DavidS said:Have you ever looked at the engine cowls of a turboprop aircraft? Have you noticed the soot? That is jet fuel for you. Jet fuel is basically kerosene of the lowest quality. It is all about making a fuel cheap enough to burn by the tons. An airliner uses about one ton per 100 km. (Aviators please correct this if not correct.)
