IMO....You could run SuperTech Dino from WM and still have great oil for 4K-5K.
I agree with the above posters, whatever is the lowest price.
IMO....For a winter run, I'd pick up some SuperTech Dino, if you can't find any name brand oils on sale.
Who knows....Maybe NAPA will have a great sale this month....when they come out with the circular for combined November and December Specials????
IMO...NAPA store brand Dino or Synthetic, is very good oil. You should keep that one on your radar.
