Yes! Techron Concentrate Plus not only helps clean combustion chambers and fuel injectors, it’s also the only fuel system cleaner that can actually help remove silver sulfide deposits which corrode sensitive fuel sending unit sensors. This corrosion can happen from regularly filling up with lower quality gasolines. Eventually, the silver sulfide buildup can lead to faulty fuel gauge readings, which can be mistaken for a broken sending unit, potentially costing hundreds of dollars in unnecessary repair bills. Many times, all you need is one bottle of Techron Concentrate Plus to help fix the problem.
