Yesterday I bought a case of 5w30 Citgo SuperGard and a local Farm and Fleet store for $9.80/case plus it comes with a $4.80 mail-in rebate. Seems like a decent dino oil with some moly in it for less than 50 cents a quart (after rebate). So, I'll be using this for 3 oil changes (probably 3,500 miles) in place of 10w30 Schaeffer in my daily driver '89 Civic Si. Specs can be found here... http://www.docs.citgo.com/msds_pi/355111.pdf
