Whoever is cheaper whenever it is time to buy.
Walmart has them on regularly for $22 then they have a 10-12 rebate most of the time.
For a daily driver, you can grab any name brand oil on the cheap when they have clearances. It seems to be happening regularly with new Dexos and SN+ rated bottles coming out. Keep an eye out in october - december for clearances on oil as obscenely low prices.
I got QSUD for $8 / 5 quart jug. Some also got the $6 rebate so it was $2 / jug. Also the Idemitsu and Havoline oil grab from Advanced auto and Oreileys.
If you're not interested in rebates, Castrol Magnetec is awsome at ~$18/jug. My tacoma ran really smooth on it. It runs a little thicker than PP 5W-30 and the oil changes looked/smelled/felt no different from normal.
More than you asked for but there you go.
