Oil Capacity between the dots on the dip stick

Dwight Frye

I keep mine topped off at the top dot all the time. Since I switched from Redline to Pennzoil Ultra the consumption dropped from 1.25 quarts/5K miles to about a half quart/5K miles so it's much easier to monitor. I don't know if the drop in oil consumption was coincidental with the change in brands, maybe it was because the engine had about 35K miles on it when I switched and was finally settling down but at least now I don't worry about the oil level dropping more than a few mm below the top dot before I see it and add a few ounces of oil.
