Engine Damaged after usage
there was no instruction on product how to use. but i used similar products before and there some minor or medium difference. car was running fine and only problem was little hesitation due to long time stopped, after changing to new oil and used this product the car started to smoked heavily, i said maybe it cleaning the engine, so i kept the car running at idle for around 40 minutes until engine suddenly started acting weirdly and completely damaged within seconds.
