| I used 0w30 in my Titan because an oil analysis showed that it worked better in my 5.6L Nissan Titan then the 5w30 Nissan recommended. This was also Mobil 1 synthetic and not Dino oil so what made the difference was the additive package used. With Mobil 1 extended 0w30 I can go 13,000 miles before the TBN gets to low. (total base number) measures the amount of active additive left in a sample of oil. |
