I have a 1998 1HD-FTE station. I have used diesel purge directly and have only used 500ml or 1 bottles of it directly. Let me know if I should go and do another 500ml on my fuel system directly. The reason is that the effect has made it turn back to life to 70% but their is still small amount of Lag still left in acceleration. Lemme know ur opinions or experiences. The car's turbo, engine and other components are perfectly fine and clean.
