Onan BFA Oil - Why not 20W-50?
Note: Our typical camping climate range runs from 10F to 115F (if we go to Redding, CA in the summer... otherwise up to about 105 in Southern Oregon.) Clearly Onan/Cummins have updated their recom...

My answer is most consumers are hypnotized and washed of cerebral neurons when it comes to motor oil selection. I gave testimony of successful operation of engines using light viscosity oil that would make sheeple blanch.
Fuel Economy and motor oil viscosity go hand-in-hand and the differential is worth noting.
The Racer's Edge, Chlorinated petroleum additives, and Telomer Fluorocarbon chicanery have all gone the way of the Ginzu knife, XV6 Battery additive, and uranium mine arthritis treatment. Colorful graphs coupled with a ring of "authority" mesmerize the gullible and there is no shortage of PT Barnum perfect examples.

Gasoline Engines
For automotive gasoline engines, the latest ILSAC standard or API Service Category includes the performance properties of each earlier category and can be used to service older engines where earlier category oils were recommended. (Follow your vehicle manufacturer’s recommendations on oil performance levels)

SN Current Introduced in October 2010, designed to provide improved high temperature deposit protection for pistons, more stringent sludge control, and seal compatibility. API SN with Resource Conserving matches ILSAC GF-5 by combining API SN performance with improved fuel economy, turbocharger protection, emission control system compatibility, and protection of engines operating on ethanol-containing fuels up to E85.
SM Current For 2010 and older automotive engines.
SL Current For 2004 and older automotive engines.
SJ Current For 2001 and older automotive engines.
SH Obsolete OBSOLETE: For 1996 and older automotive engines.
SG Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1993. May not provide adequate protection
against build-up of engine sludge, oxidation, or wear.
SF Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1988. May not provide adequate protection against build-up of engine sludge.
SE Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1979.
SD Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1971. Use in more modern engines may cause unsatisfactory performance or equipment harm.
SC Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1967. Use in more modern engines may cause unsatisfactory performance or equipment harm.
SB Obsolete CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1951. Use in more modern engines may cause unsatisfactory performance or equipment harm.
SA Obsolete CAUTION: Contains no additives. Not suitable for use in most gasoline-powered automotive engines built after 1930. Use in modern engines may cause unsatisfactory performance or equipment harm.
