Have you ever seen a Mighty Mouse slant 6?
I have a lot of respect for the /6.
Years ago when I was 19, daily driver 1974 Valiant.
Oil light came on, so I pulled over to check the dip stick.
Very low, & milky, a combination of oil & water.
The closest place only had oil for Marine outboard lower gear lube.
3 quarts bought & it still survived that way for months until I sold it to a guy for parts.
It still amazes me.
