Dear Mr. Stevens,
The Product Fuel Set was used by servisair at Belfast International Airport on Transit Vans.
We found that the emissions were cleaned up (black smoke that was) and, the engine run without ‘pinking’.
Also, we haven’t experienced any pump or injector problems while using Fuel Set. I would have no problem recommending this product for engines which experience excessive idling & carbon build ups.
