Yes WAY!

I recently stopped in at our local NAPA to buy a NAPA Gold oil filter for my truck (2021 F-350 Powerstroke). I was told over $60 was "my price" which is supposed to be a discount. I came home and ordered 2 Motorcraft (original equipment) for $18.99 each from Amazon. I now have filters for 2 oil changes for less than the price of one NAPA Gold filter.

  As for NAPA in general: the local stores around here are about as much a waste of time as any of the TSC stores. I know where I can get what here locally and beyond that I start making phone calls to places like Sandy Lake Implement and others.

       I buy all my tractor filters through Shoup. Baldwin, everything from the U, UC, WD, CA(all the same) 190, 200, 8010, 7020, 8050's, 8070, oil, hyd, fuel and many air filters. The Napa oil filter for the R62 8.3 was $103, If I remember right, it was less than half that through Shoup. No shipping charge on orders over $200.

Color doesn’t say who made the filter. Donaldson and wix are both white.

Lots of complaining about NAPA but no one really answered the question.  Back 20 or so years ago someone redesigned the filter.  They went from the cotton thread media to a pleated paper.  The W engines NEED the cotton as that restriction is what helps provide oil pressure.  Paper media had no restriction and an already low pressure system ran on basically zero pressure.  Didn't take only a couple of years for them to realize they screwed up and all mfg went back to cotton media.  As long as your filter has cotton thread tightly wound and a hole up the middle for the stand pipe, it's perfectly fine to use.

I don't know these engines at all so keep this in mind but is this a full flow, or bypass filtration system? Utilizing a restrictive filter to maintain oil pressure in the engine? I've never heard of that in the past. Though years prove me wrong, this reads of a design destined to failure without strict adherence to filter selection unless it is a bypass type system rather than full flow. I have several engines utilizing bypass systems only and they work well so find this interesting.

I don't patronize my local Napa parts store but that is a business relationship and pricing is just the start of it.

Thanks Cal. Makes sense now. 

I have several antique Mack engines utilizing bypass filtration only and they work well.

The BYPASS runs about 15% of the oil thru a 1/4 inch tube with an 1/8 inch hole in the end as an ORIFICE to restrict the flow.. That 15% then goes thru the TIGHT WRAPPED COTTON filter which further restricts the flow.. and then dumps to the crankcase.. About 85% of the oil goes to LUBE  the motor.. If you take out the 1/4 inch tube, you will run about 100% of the oil back to sump.. NO LUBE.. If you use the PAPER filter instead of the COTTON, you loose a good portion of the oil back to sump.. I dont know the %, but you probably had ZERO LUBE OIL at low or half throttle.. and MINIMAL lube at HIGH.

The first time I pulled an oil pump out of a Model C engine I literally laughed in disbelief, that's how puny it looks. A dinky little vane pump driven off the end of the camshaft.

So yes, if you poke a hole in the system ANYWHERE it is not going to maintain pressure. "Modern" engine design uses a big, robust oil pump that can deliver excess volume. The older AC systems are adequate. Just. Barely. Adequate.

in comparison, my F150 has a duel turbo 213 CID engine that is close to 400 HP ! 

I've long envisioned turbocharging my old wind up West Bend bedside alarm clock but I'm afraid that one hasn't quite gotten off the drawing board as of yet. Can't seem to find proper packaging to allow a workable fitment with thermodynamics considered. This on top of of space constraints, cannot for the life of me figure how to fit charge air cooling to the unit as I've had the thing so long as a passdown from my grandparents, I'd sure hate to melt it down, yet I'd still like a bit more performance.

Any engine takes to turbocharging like a duck to water if it is set up correctly. Got to control the heat, contain the pressure, absorb the inherent torsional stresses induced, and direct the power to a usable output to make it work. Easier said than done with engineering, manufacturing, marketing, and management involved in the mix. 

I had a 1989 Dodge Spirit car purchased as a bank repo to use as a loaner in the shop. Very clean little car with a blown head gasket but ran well. It was turbocharged but not intercooled. I pulled the head finding it cracked and ordered a new one from an aftermarket supplier along with an updated "graphite" head gasket. Installed new timing belt and water pump at the same time along with new hoses and drove that car to just shy of 400K on the clock with no trouble other than an air conditioning compressor going bad from age. It never did get used as a loaner my wife liked it so much. It really "woke up" after installing a "Mopar Performance" ecm, and Borla exhaust too without being very loud. Had a great tone, but not annoying.

Never did use oil between 5K oil changes but rust put it down as wasn't safe to drive any longer.   

I did try something for the heck of it. I decided to add a little zinc additive to the oil, and I also threw a little Marvel's in the gas tank and crankcase.  It literally cured my blue smoke issue on high throttle out in the field, and the oil pressure is better.  Normally my grandpa can see blue smoke out of the exhaust pipe if I am way out in the field, and the dark trees provide a backdrop otherwise the blue tint is hard to see.

After running it hard for about 2 hours it didn't use a drop of oil. Normally I see at least a 1/2 quart down.
