Do I have any concern now?
2007 Chrysler Seabring 79,000 miles
In March I had a serious condition where the car was idling rough and the check engine light was flashing. I took it to the dealership to get the scheduled maintenance and the mechanic told me that the engine was sludged up, I was losing compression in cylander #3 and I was getting blow by. He also told me that due to neglegence it would not be covered under warranty and it could cost anywhere from $400-$4,000 to repair. Well, I asked what could I do to get it to be covered under warranty. They told me to flush and change the oil at least 3 or 4 times. I picked up the Gunk Motor Flush, Gumount Complete Fuekl System Cleaner, Synthetic Blend oil, FRAM High Mileage Oil Filter and BG MOA.
I have changed to Penzoil's full synthetic with cleaning agents and use only Shell gasoline. Now the car runs like a dream, no rough idle, no check engine light and no blow by. Everytime I change the oil I use the motor flush first, change the oil, add BG MOA. I also use the Gumount CFSC at this time as well. I hope I have dodged a bullet that could have been extremely expensive, but I got insanely lucky.
