I have used a fair bit of Valvoline DuraBlend 10W-40 Synblend, probably pretty much the same stuff but without the seal conditioners that MaxLife has.
I think it was a good oil that performed well. No used oil analysis done, just seat of the pants stuff.
Synblends or semi-synthetics seem to be the minimum required to meet Dexos or A3/B4 specs, so they tend to be good value oils that deliver good performance. My two favorite synblends would probably be Valvoline DuraBlend (or MaxLife) and Castrol Magnatec.
