Engine- 94 351 Windsor 125,665
Oil- 5w30 Supertech with maybe 1/2 quart of 5w30 Carquest. This was a Auto RX rinse cycle.
Miles on oil- 2845
Filter- Motorcraft FL-820S
Truck- 94 Ford F-150 Supercab 4 by 4 Automatic
All other not listed were O
Aluminum-1
Chromium-0
Copper-3
Lead-27
Tin-4
Moly-91
Nickel-1
Potassium-1
Boron-3
Silicon-8
Sodium-29 I started with a Supertech oil filter that was crossed with the Motorcraft. Well the supertech filter did not seat correctly and I had a oil leak. I went down to the ford garage and purchased the better motorcraft filter and had to replace and bit of oil and that was the Carquest oil. That is were the Sodium is coming from in my opinion.
Calcium-1691
Magnesium-12
Phosphorus-614
Zinc-783
Barium-0
SUS Viscosity at 210 F-57.9
cSt Viscosity at 100 C- 9.62
Flashpoint in F 400
Fuel Antifreeze-? That was from Blackstone
Water 0
Insolubles- 0.3
Tbn 1.9
I did run a one time treatment of STP fuel and combustion chamber cleaner in the gas. The ingredients said it was composed of part Jet Fuel. I wonder if this was the cause of high lead. The truck is driven in the mountains and did see some hauling but silicon is low and the other wear metals are low. Could this engine need a higher viscosity oil or was the fuel system treatment the root cause of the high lead. Before I got this report I had changed oil to RTS 5w-40 thinking that would be a good match. The engine hated it on start up. Something in the top end like the rocker arms or connecting rods rattled for a few seconds. I dumped the oil and went with 5w-20 Quaker State peak performance. No more start up rattle. I did not have any with the 5w30 either. This motor is back dated for 5w-20 but again it was put in before this report came back to me. What do you all think. Thanks in advance.
