I just started using it about 2 months ago in my shop. My commercial acct prices places the oil close to what we used to pay for supertech syn at walmart and I do think it's the same oil. I don't have any proof or tests but it does meet Dexos and other specs I like so, to me, it is a decent oil to use in recommended oil change intervals. I wouldn't feel confident stretching it out like I would a Mobil 1 EP or similar but it is better than most of the bulk oil the quick lubes use in my opinion. I don't have any issues using it - I did just for the 1st time put it in one of my personal vehicles and plan to run a UOA on it and post. It's in my Hemi Ram so it will be ran to about 7-8k miles when my change oil prompt comes on.
