Subject vehicle is a 2012 Toyota Tacoma with the 2.7 inline four cylinder. Just turned 40k and the oil history has been all AFE 0w-20 at 5k intervals. I run mostly highway miles with some use of the four wheel drive. Is there any benefit to using the tgmo 0w-20 motor oil? Obviously that oil has a higher viscosity index, but Mobil One has better cold cranking properties I think. Price on M-1 is 26 dollars at Walmart and I do not know the price on the tgmo. Any benefits to switching?
