After got rid of my last GM car, discovered some bottles of AC-Delco fuel system cleaner. I know everyone says Techron is among the best if not the best, but would the AC-Delco be safe and/or effective in my 2010 Toyota Camry with about 110k which has not had much fuel injuector cleaner through it except some Lucas with the upper cylinder lubricant. All responses apprecated. If the AC-Delco is not safe for the Toyota, would it be safe for a 2014 Kia Forte with the 2.0 GDI engine? Thanks in advance to everyone.
