Bumping this. Has anyone had any issues with the use of techron fuel system cleaner? At 30k miles, im wanting to use something to clean the fuel system, just in case, but am a bit worried about any long term issues, if any. Ive used fuel system cleaners in other cars without any problems, but i do ask because of what ive read regarding nissan not recommending using additives and/or cleaners of this type. Thanks guys
