this link is probably one of the best (and most exhaustive) studies on lubricity for diesel fuel and will address some myths....

Just curious, why use both? Cetane boost and anti-gel with Power Service and more lubricity with the 2 stroke? At 1oz/gal, why use more than the study recommends? Which 2 stroke oil do you use?

I just bought my first diesel pickup yesterday....2001 F250 CCSB 4WD with 7.3 PSD so I'm new to this stuff.
