Ive seen the black bottle of Concentrate Fuel System Cleaners in Caltex service stations. What is the difference between those and Techron®?
The principal difference between Techron® and Concentrate Fuel System Cleaners is additive concentration and rate of deposit clean-up. At the concentration present in Caltex fuels, Techron® over several tankfuls will help clean up deposits on intake valves without contributing to combustion chamber deposits. So, over time, Caltex with Techron® will be able to reduce or eliminate deposit-related hesitation and stumbling during acceleration. A bottle of Fuel System Cleaner, when added to fuel according to the label instructions, results in an additive concentration roughly 10 times stronger than the dose in Caltex. This mega-dose of cleaner provides a much quicker clean up of intake valve deposits left by lower quality fuels. In addition, the high concentration of the Techron® in the cleaner reduces combustion chamber deposits, which can help reduce or eliminate deposit-related engine knock and run-on.
