All oils shown are on the 2nd fill.
99,986 - Changed air filter - NAPA Gold
103,611 - Oil changed with RLI 5W20; oil filter changed with AMSOIL EaO20
106,708 - Added 0.5 qt RLI 5W20
109,422 - Removed & cleaned intake manifold & EGR passages with IPA, & throttle body with AMSOIL PowerFoam due to code P0401. It was very 'carboned up' IMO.
110,045 - Added 0.5 qt RLI 5W20
111,194 - Changed air filter - NAPA Gold
111,369 - Added 0.5 qt RLI 5W20
112,389 - Replaced EGR valve
112,518 - Drained oil, changed filter, & collected sample of oil that had 8,907 miles & almost 4 months use.
Code has still not been eliminated. Will try & perform the actual TSB fix with the manifold tweak (EGR pipe kit).
