Agreed!!! Made this mistake on my eg hatch built the motor to handle more boost and used full synthetic oil and K&N oil filter after about 1 week of break in I started to notice my temp gauge rising a bit and more smoke than usual coming from the exhaust. Then with in 2 weeks it got a lot worse. So I stopped driving it after my fear became a reality I fried my rings and seals due to blow by and excessive heat for using synthetic after a completely fresh rebuild. But a friend of mine did the same thing and never had a problem. So good luck and welcome to the site! Pics would be nice
