I have just purchased a 2019 Buick with the 2.0 turbo motor. This is my first D.I. engine and have been reading about the problem with carbon build up on the intake valves. It appears to me that the oil from the EGR valve is what is causing the problem. I can not see anything else that would cause this build up. I have some experience with low saps oil from my Mercedes diesel days and was wondering if a low sulfated ash oil would help this problem. I have been using Mobile 1 emission system protection 5W30 synthetic oil. This meets Mercedes 229.51 specs for a low saps oil.
The car only has 20k miles on it, so I do not think it is a problem yet. I think I will do a CRC intake vales cleaner treatment just to be sure. I am looking for some advice on the low saps oil. Do you think it would help stop the carbon build up? Thanks Roger
