Where Is My Engine Oil Going?
And the OP`s bike is not using enough oil to even be worth mentioning, if it is using oil at all....
Street glide doesn't drink a sip.
Heritage takes 1 quart every 1.5k. Within Spec.
Does it bother me?
Nope, I ride and enjoy both!
That level will not change unless you add oil or oil leaks out.
Just remember to check the oil level hot, and do it the same way every time.
I've been researching this M8 and what HD has done to rememedy the oil issues since it's early stages.
The M8 early oil pump was a bad design and revised 3-4 times before they finally come out with the 2020 new designed oil pump but those were not installed until sometime in June of '19.
HD also issued a service bulletin in March of 2020 stipulating all M8's would get the new designed oil filter at next service.
In other words, the MOCO released the M8 and has been trying to deal it's oil delivery system since day one.
Below are the part numbers for the new oil pump and the filter. The new oil filter will be a 1/2" longer than what it replaced.
I've found several dealers still using and selling the old oil filter stock and not adhering to the service bulletin.
M8 oil filter # 62700296 (filter is 4" tall)
M8 2020 new design oil pump # 62400247
I went through the same thing you did with no oil on the dipstick at 2500 miles. I changed fluids and installed the new designed oil filter, also installed the new oil pump when I cammed it.
It was a 1/4 quart low over the next 3K miles, which is more like it.
Good luck with it, Galveston, keep an eye on it.

I don't trust the MOCO, they have answer to all their problems so long as it doesnt hit the recall button.
