Was curious about mobil 1630 since it has a advertised 12 tbn but could not find an analysis report of it on here so i bought a gallon of it to try in the lawnmower and sent a new sample to petroleum technologies. Here are the results!

Main ones i'll hit on

Cst- 11.3
Calcium- 3929
Magnesium- 242
Zinc- 1108
Phosphorus- 958

Your lawnmower will be happy.
I've bought pails of 1330 in the past, the last one in 2019. I think Mobil discontinued their 1300 series mono grades.
Many HD mono grades are blended from group I, but don't let that stop you.
Nothing works better for cleaning up an old engine like Mobil's 1600 series, Delo 400, Duron and other Non-CF-2 approved HDEOs.
The above 1630 works well in dirt bikes and quads and other shared sumps above freezing where an Xw30 is recommended.
Wet clutch compatable.

I don't understand your commitment to your lawnmower engine but do admire your level of zealousness.

I didnt buy it specifically for the lawn mower lol but it needed an oil change anyways and being its a 40 year old single cyl 16hp briggs with no oil filter might as well treat it well for as long as its treated me. bought it cause i thought this might be a good poor mans valvoline vr1 oil for a hot rod or race car but with the extreme level of calcium i dont know, lake speed jr likes the newer oils with much less calcium to offset the zddp package and also with 1108 zinc and 958 phosphorus its nothing high to write home about, but none the less it'll get used and now i know the answers i was looking for.

Thanks for doing this, very interesting to see what is in ‘oddball’ oils these days!
Very stout, as expected, would work well in older cars during the summer.

The additive package looks like a Cat TO-4 disguised as an engine oil.
Remove the Zn, and you have a locomotive engine oil.
Legacy lubricants and engine oils have been around for decades and pre-date Greta's CK-4 by 70 years, and now are blended with
better base stocks and modern chemistry.

Thank you for providing this VOA! I am a fan of monogrades that have no viscosity index improvers. I also like lots of detergent/dispersents.
