I have been running Chevron Delo 400 LE in my 1999 Ford Superduty with a 7.3 for a while now and pretty happy overall.
At my last oil change I found it a little challenging to find LE, most have been replaced with SDE. A quick look at the specs and I am a little worried to switch over with its lower zinc and phosphorus content.
I was working at a hot rod shop when they were dropping zinc content from automotive oils and saw the impacts onto older hardware (flat tappet cams with aggressive ramp rates and high spring pressures), so I might be a little paranoid here.
What are you guys doing? I am leaning toward changing brands...
