NASA did a big study on oil additives and concluded that they aren't worth dpg ****.
I use an oversize filter, Motorcraft Racing Filter FL1A, or K&N HP-3001 (rqted for 12 - 16 gpm). You can also use the oversize Fram racing filter HP-1,l which I don't think is as well made.
I need 5.5 quarts of 10W-30, usually Castrol or Valvoline non-synthetic.
The K&N ovrsize is still only rated for 12 to 16 gpm.
What surprises me is the small filter Ford requires as stock for an oil pump that can put out 20 gpm at redline. Granted you're not runnning this puppy at redline, but when you run it hard, that filter just seems to be too small.
Also, be careful on fitting and line sizes when relocating the filter. Most spin-on adapters have 1/2" ports and most kits use -10 AN hose. The pressure drop through a 1/2" port or fitting is HUGE at 20 gpm. (Refer to the Parker Fittings website and their graphs of fitting pressure drop as a function of oil flow; Parker has a division that makes fittings and hoses for Formula 1 racing cars and a division that makes fittings and hosefor the aerospace industry).
Same for a -10 AN hose. You can undo the convenience of relocating the filter by reducing the oil flow to the engine (or increasing unfiltered oil to the engine) when the oil pump relief valve pops (oil filter bypass valve opens).
You can find spin on adapter plates that have 5/8" ports; 3/4" would be best. And I wouldn't use less than -12 AN hose (as also recommended to me by the boys at thinkauto.com, a UK firm who specializes in oil coolers, etc.).
I just don't think it is worth it to relocate the oil filter and incur all that pressure drop which may reduce oil to the engine or increase the amount of unfiltered oil to the engine.
Now if you want to install an oil cooler or a bypass oil filter, which filters a slip stream of the oil to 1-2 micron levels, then you're OK.
I'm installiing a remote mounted bypass filter. Studies indicate the the oil stays clean and doesn't change color. Trucks have run on NTZ byapss filters for hundreds of thousands of miles on the SAME oil. NO OIL CHANGE!
Ford is now installing these types of filters on their automatic transmissions because the allowances for particles in an automatic transmission are becoming tighter and tighter.
Check out the NTZ website.
I'm installing it because I'm just curious to see how clean the oil stays and how long the additive package is maintained with oil analysis.
I definitely don't think there is any need for a bypass oil filter, but my curiosity is driving me to install it.
Curiosity killed the cat ---
But satisfaction brough him back!
