Nicely compiled and well put Tyler. I personally also use the oils that are on sale from Autobarn and most often are all of the 15/40 variety.
To date, i have had no issues with any of them and as you said, "anything is better than the sludge normally found in briggs sumps."
Admittedly. i like to use a 10/30 for hondas and use monograde 30 for any briggs that may still be within the warranty period, although these types of services are far and few between.
Cheers, Ted
