I used Mobil 1 5w30 for about 2500 miles and the oil pan gasket started to leak. With the Honda motor oil I had no issues. SO I plan on switching back to my Honda 10w30 for the summer. Are there any other steps I need to take(besides a normal oil change) when switching from a synthetic oil to dino? Should I change my dino oil sooner perhaps at 1000 next time instead of my 3000 to eliminate the tiny amount of synthetic left behind? In hopes of flushing out what was left behind. Feedback would be appreciated.
