 Dirty Oil right after change ?
Hello Everyone, I just bought my first used Duramax, Its a 05, GMC, LLY with 58,000 miles. The old oil had 5,000 miles on it and it was very dirty looking. I went over the fluids and filters, Changed motor oil + filter, Trans oil + filter, Fuel filter, Air filter, and Transfer case oil. After I changed all theses I ran the motor for about 5 min. to check for fuel and oil leaks, everything was fine, I then checked the motor oil and could not believe my eyes, It almost looked as dirty as when I started. Should I change it again in about 500 to 1,000 miles or is there a way to flush the motor. I dont think this is normal ? No service engine light, Everything seems to be normal, Any insight or help would be greatly appreciated, Thanks |
