Is BG 44K fuel Injector cleaner okay

I wouldn't use it. #1 is it's too expensive, #2 it began it's life as a heavy truck diesel treatment, so who knows what it would do to electronic injectors. If you haven't been using top tier fuels the grab a bottle of Techron and dump it in on your next fill up, this stuff saved me from having to buy a complete fuel injection spider in my old Yukon. But if you have been using top tier fuels then it not needed as the fuel contains enough additives to keep injectors clean.
