Sometimes its nice changing it every 3 months regardless just because that gives me 1 day out of 90 I can tell the woman I have to spend the day at the garage..........which is well worth the cost of the oil change. She some times asks why it takes 4 guys, 6 hours, and 3 cases of beer to change the oil.

 

In return, ask her why it takes all her friends to walk with her to the restroom while enjoying a night on the town.

 

Yes NAPA Synthetic is actually made by Valvoline.
