I have a Harley road king that I use vr1 20w50 synthetic in that I got at autozone for 1.86 a qt, the primary gets rotella 15w40, the trans gets motorcraft 75w140 synthetic gear oil.
60k miles and zero problems, I boroscoped the cylinders and the crosshatch looks new.
Put the jack on the oil pan with the wheels on the ground to support the engine.
then you can align the mount easily. It looks like you have cross threaded the bolt,
A thread chaser or tap should repair the threads in the mount.
there is a slot on top of the mount that fits in the aluminum...
A friend of mine was an engine builder for a race team sponsored by an oil company.
He has told me more than once that they never ran the sponsors oil in the race engines
