NAPA Universal Fleet Plus, 15w-40, CI-4Plus, (high zinc/TBN/calcium). At $9.55 per gallon, 2.39 per quart, it is tough to beat!<<<< You can add both Citgard 500 and Citgard 600 in all weights from Citgo to that list. Ignore the Chavez crap for a minute. I also found 28 cases of the Citgo Superguard 10W-30 in Semi-Synthetic with an API rating of SJ; (does not meet the new standards for lowered ZDDP content.) Citgo also makes Mystic JT-8, which comes in both dino and semi- synth. I had to leave them off my chart due to not being able to confirm their TBN/Ca/Zn composition. Someone send me either an official PDS, or an independent VOA, and I would love to add them here and in the prospective Avanti Magazine Article. I do know the Mystic JT-8 was very well made 3 years ago, and even has a 15w50. As for joke-a-minute Chavez, I love that guy. He keeps stealing from his poor and nationalized oil workers to either give away billions away to our poor, or to undercut US company's pricing, note Mystic's price. How he keeps from getting a bullet in his head from his own people, for his massive subsidizing the great Satan US, I will never understand.
