Hi Tdmsu:

___0W-30 will help in the winter at initial light off when the oil and block are absolutely stone cold but as your ICE warms up to operating temps, that 30W will kill its FE capabilities vs. just about any other 20W out there. Even Amsoil’s 5W-20 has a higher 0 degrees and 100 degrees C Kinematic viscosity vs. Mobil1 0W-20. If you can find any Mobil1 0W-20 anywhere, buy it. The new Pennzoil - Hybrid 0W-20 is an unknown and until it is available for analysis or Pennzoil posts the kinematic viscosities, we won’t know if it is any good for maximum FE and protection or not? Its minimum pour point has been released IIRC but the devil is in the details …

___Good Luck
