New Vanguard Oils

[12-Valve]

Was looking around for maintenance kits for my vanguard 37 hp and came across this. Looks like Briggs is adding more synthetics that I have not seen before and a different label. Was only aware they made a synthetic 5w30 and 15w50 before. Only info I can find on it is that it's made for power distributors.

Apparently, there is also a 10w40 and 15w40 oil as well. Found a pic of the back of the 5w30 vanguard oil and says it meets/exceeds API CH/SJ.

The SJ rating is 20 years old

All the small engine makers have moved away from the standard 10w30 weight they've recommended for years. Not sure why though.
