Yes, Seafoam has become part of BLURs balanced diet. The last visit she had before her first Seafoam treatment was for a Dealer-style carbon treatment. BLUR coded yet still and once we performed our home Seafoam treatment BLUR was codeless for quite some time. The Seafoam treatment, along with all the other tinkering, allowed the techs to finally see the real issue. Carbon buildup is as real problem but a little MINI PMS goes a long way.
Reminds me that I need to hit Fairfax Motors for my in-between oil change.
