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. --- _[View the full topic](https://forums.speedlife.net/t/swithing-back-to-conventional-oil-from-synthetic/21952)._
