I just noticed this Conoco Syn Blend listed for sale at the local distributor. It's very cheap, much cheaper than Kendall, and I think the cheapest SN/GF-5 30 grade I have found to date. Any reason not to use it? Any better or worse than Mobil Super 5w30 (syn blend) which is at least 50% more expensive? I would have to use the 10w30 as it is the only grade available. I like that it comes in a box of 12 qts, not 5L jugs.
