gents, seek and buy a bottle of archoil 9100 and douse your oil... the stuff is fantastic with HEUI injectors, and eliminating stichion.
also of note, and again related to those HEUI injectors- they sheer down 40w oil to 30w in rapid fashion... that's what happens when motor oil is used as a hydraulic oil... curiously, it doesn't sheer down 30w... this is based off of hours and hours and OCI after OCI with laboratories and analysis done religiously... so... use a 30w to begin with, and avoid the issue of degraded oil... yeah, ford won't 'approve' it, but it doesn't make it any less true- and we're far past the warranty phase, anyway. 30w is better in HEUI equipped engines.
