4.6L Oil improvements
Here are three modifications I made to my Ford last year for improved engine life, reduced oil oxidation and contamination.
1) Switched to Purolator PURE-ONE high Beta ratio spin on oil filtre
2) Stripped an engine oil cooler from a F250LD 5.4 L at a local wrecker. Installed same on my 4.6L c/w remote oil filre mount.This is a fairly straight forward installation for an evening's work.The oil cooler is basically a small plate heat exchanger with oil on the hot side and coolant shunted through a special lower rad hose to the cold side. The cooler strips out about 40-70 deg f heat from the oil in the summer and in the winter the warmer coolant reheats the oil to prevent formation of water solubles in oil. I talked to the guy at Long Corp in Burlington, Ont who actually designed the unit for Ford. He advised me leaks were not a problem and did not know of any warranty returns from Ford, confirmed my heat rejection,etc. One other advantage is the oil is now cooled before it is filtred which the oil filtre manufacturers like for improved paper media life and reduced fibre binder degredation. I have an oil cooler on my 350 GMC 3500 truck, 1985, stripped the engine down at 80000 miles and couldnt find a brown smudge anywhere inside. The 350 Jimmy looked indistinguishable from the day the boys in St Catherines/Oshawa assembled the engine. So I know its going to work in the F150. I paid 125 $CAD for the whole works hoses incl. You can get all the parts nos from Fords Parts manuals
3) I installed a Temro/Budd Oil pan heater 300 watt and the oil panheater is plugged in with the block heater. It will keep the oil at about 100-120 deg f when the outside ambient is less than -20 deg f. Instant oil pressure when you start, faster warmups, less water in the oil. The pan heater straps on the side of the pan on the pass side which helps convective heat transfer to oil and keeps it out of harms way for winter or summer offroading.
Remember you are buying low viscosity index and oxidation stability with a synthetic oil but water and particulate contamination are cumulative regardless of the oil. Stabilize oil temperatures because the engine will reject up to 20% of its heat through the oil The cast aluminum oil cooleed pistons will love it regardless of how hard the 4.6L works.
