fuel additive to clean injectors

no additive will clean like the direct injection method you got. the price is a little high but well worth it. Roy

I use Shellbourne Fuel Enhancer at every fill-up. Keeps the fuel system clean, cuts emissions +60% (no black at tail pipe) and no clogged injectors. It's worth the extra 11-cents/gallon. Now that Winter's coming, I can look forward to instant starts down to minus-45 F. Yes - there is a fuel enhancer that is worth more than its cost.
