Well its been months since I have been on the board and I was going into serious oil withdrawl.
But now the move is complete and I have a UOA ,under conditions I would consider extreme, to post.
Here' s the background. 2002 F350, with 36,267 on it. I changed the oil and filter at 25,000 and installed a bypass oil filter at 30,000. At that time I put on a new amsoil filter and added 5 qts of make up oil.
We were moving, so the Truck was pulling a fully loaded travel trailer with a cgvw of 16,800.
We moved from WA to PA. We took the southern route through Vegas in AUG and up through UT, CO and then straight across. The truck saw temps of 115F for hours on end and climbing grades of 7% and altitudes of 10,000FT over in CO. So this was a good test for the oil. Additionally since we were camping we experienced lots of dust.
The oil is currently still in the truck and I am awaiting Terry's expert advice.
Here are the numbers:
Aluminun- 2
CHROMIUM- 2
Iron - 34
copper- 7
lead- 4
Tin- 0
Moly- 1
Nickel- 1
manganese-1
silver- 0
titanium- 0
potassium - 7
Boron - 0
Silicon - 14
sodium - 2
calcium- 4120
magnesium - 9
phosphorus -1064
zinc- 1209
barium - 0
SUS viscosity- 69.4
Flashpoint 465
insolubles - .5
TBN 9.4
