It worked great couldn't be more satisfied
dorve for few km's after flushing and adding the decarbonizer and smoke stopped engine running like swiss watch and purr's
Flushing oil concentrate worked perfectly. I previously carried out a flush with 2 bottles of Nulon engine flush and new oil and after draining and renewing oil and filter, the oil was as black as when I started. I drained the oil again and replaced with fresh oil and flushing oil concentrate, ran the engine on fast idle for 30 minutes, drained the oil and replaced filter. Filled with new oil and run the engine for 10 minutes and the oil is clean as when I poured it in. Excellent.
Used many times and always happy with the results. I'm constantly telling friends and family about how good these products are.
Reduced blow by, by 85%. Thanks so much.
don't know why but its like it got worse
