"I have left this review around 6 weeks after the product arrived giving me time to test it. This works. I have noticed a definite increase in overall engine power and acceleration. The engine is much quieter at idling speed. I did have a slight problem with black smoke on heavy acceleration however since adding Oilsyn this has resolved the problem after around 3 weeks. Excellent product" - Diesel Power DNA
