NAPA currently has their full synthetic on sale (It's for the month of April) for $3.49 a quart. They also have 5 quart deals with a Silver, Gold or Platinum filter. Their synthectic meets SN and Islac5. Not a bad deal! Here's the flyer: http://specials.napaecatalog.com/Web...kCode=apr13flx If you buy the Platinum filter deal the oil ends up being $2.50 a quart. (plus $3.49 for the 6th quart, so your total oil cost is $2.66 a quart) The part number for the Platinum filter is 41334.

That is what I have used. Napa oil is made by Valvoline and just rebranded with their label.
