What a bunch of "S". ;Þ
The N-Fords were originally expected to run their entire lives on straight, nondetergent, non-rated mineral-based motor oil. No additives. No multiweights. No "S".
Nothing has changed...except the oil now is tested to higher temps, and has anti-foaming, anti-rust, anti-scuffing additives. The rating change to "S" does not hurt a danged thing. Nor does it make a bit of difference to your N-Ford. You want to keep your engine operating a long time in-expensively? Use WalMart's (or anyone else's for that matter) cheapest, store-brand oil, that meets car maker warranty, preferably in a single-weight oil. Any rating (SL, SJ,etc) is just fine. SAE 30 or 40 is great. My 1992 Jeep Cherokee is running on 278,000 miles now on WalMart SAE 30 SuperTech (less than $1/qt) and $1.49 filters. My 9N Ford is running on old, expired, SAE 50 wt aviation, straight, mineral non-detergent oil with a whole can of WalMart SuperTech STP-clone poured in for anti-scuffing. (STP oil treatment, and WalMarts copy of that product (.88 cents) is a zinc dithiophosphate additive for anti-scuffing,...same stuff put into modern oils for the same purpose. The local oil supplier had a 20-year old damaged case of non-detergent aviation oil in cans (Mobil Red-Circle) and my 9N loves it, burns none of it, and keeps it's oil pressure up on blistering hot Texas summer days mowing/shredding with a goldenrod-chaff-choked, half-blocked radiator. Good stuff. Cheap and good. Don't fall for that high-priced stuff because as long as you change it regularly and use a good single-grade oil, your tractor will think it's being treated well. (Despite my use of cheap oil and high mileage, my vehicles still don't burn oil and I intend to keep on doing it just like always.)
