Stop being a cheap and run the good stuff. It works out to about $1.44 a day extra it’s costing you.
12000 miles a year, 4000 mile change interval = 3 oil changes in a year.
3 x 5quarts x $7 = $105
3 x 5quarts x $2 = $30
Besides that, if you buy it by the case at BJ’s it’s less than $7 a quart (Mobil 1)
EDIT: Warning, don’t do math high on nyquil. It’s .21 a day.
