The details:
Truck: 1999 Ford F150 Supercab Flareside 4x4
Engine: 4.6L 16V SOHC V8
Tranny: 4 Speed Automatic
Oil Filter: Purolator Pure One
Air Filter: Fram (in use for 19000+ miles). Not happy with the "new and improved" design of this filter in terms of fit in the air box, but see the UOA results below. This filter looks trashed at this point, but again, see the results below.
Driving: 60/40 Highway/City. No towing this period. 750+ miles of gravel road gravel Road driving.
Weather: From October '05 through March '06 in Minnesota, a bit warmer than usual. Still a good number of below zero mornings and days to test the oil a bit.
Analysis: Blackstone
Cit=Citgo Synthetic 5w30
Rot= Shell Rotella T Synthetic
No problems with cold starts either. Worked fine on my 6.5 year old OEM Motorcraft battery.
Make up is higher running the 5w30 versus the 5w40, but still below 1 qt per 3000 miles, which is where this engine has historically been in its life.
The Fram air filter looks absolutely trashed at this point. Likely one of the dirtiest filters I can ever remember pulling of this truck! You couldn't tell from the UOA!
I'll be replacing the filter with something besides a Fram soon due to my percieved feeling of a poor fit in the airbox. Again, the UOA may not bear that out, but what can I say?
I put in Citgo Syntheic 5w30 for the next run. This batch is also the SL variety. The new SM variety had arrived at the store the last time I purchased it, so this will be my last run on the SL flavor.

So, I went 1000 miles further than I intended. With the extra mileage and winter weather, I've got no complaints on this UOA. For the $3.00 a quart oil (last time I bought it on sale anyways), looks pretty good for what is assumed to be a group III synthetic oil.code:
