put in 6, then check level with dip stick.
regardless what it says on stick, you will know
thats the full amount indicated on stick.
But you want to check oil level with engine warmed up I think.
Also, I run a quart low to help make more power. I have a 7 quart pan.
Lower oil level means less windage horsepower losses from crank (oil collecting
on and splashing on crank at high rpm).
