I have used it on my Nissan Versa Note. Nissan wants a 3750 mile OCI for severe driving conditions. Well I am equating those conditions to our local stop, go, dusty streets driving. I have used Supertech synthetic 5w30 and changed it out at 3000 miles. I don't do the other 750 miles because it is just simpler to do it at 3000. I don't use an expensive filter so things stay pretty cheap doing my own oil changes. Three 5 quart jugs can do 4 oil changes with as small a sump my vehicle has. Being small as it is I do want to change the oil out regular like Nissan has required.
I'm probably going to run 5K or 6K on my Jeep with ST 10w-30 synthetic. My Jeep gets used like a Jeep, though. Towing (750 miles so far this OCI has been towing) and off roading trips where it's idling or running all day. It doesn't see commuter duty any more.
I did a test back in '08 with ST Syn, it did perfectly fine @ 5000 miles 90% highway, and could have gone further. YMMV, but I'd say at least 5k and maybe more based on your UOA. It's a decent oil, made by Warren.
My buddy did 18,000 miles on his old Chrysler minivan (85) with no repercussions. But he probably added 5 quarts getting there. That engine was so quiet you could barely hear it running.
