Same here Trajan. Both my Nissan's spec API/SL-SM and recommend mineral based oil. OCI 3750 Severe or 7500 Normal conditions. I meet in the middle and go 5000 on both vehicles. I am running Penz. Platinum Grp III right now (got it for a good price), but will start using PYB. Reason: Price. I am quite comfortable using a quality, name brand oil that meets the automaker's specs. I can get 12qts PYB for about the same cost as 5qt jug of platinum. I use quality filters too.
