But I wanted to remind you that you can ask them not to wash your engine. One of my friends (He is also giving his car for washing to Teyseer weekly) told me that for the few last times they asked if he wants engine to be cleaned because Teyseer got some complaints about the same problem. I just wanted to remind people that they shall not ask for cleaning engine frequently. Thats it. Otherwise if you want a clean engine you can take that risk :).
