Is Chevron Supreme still a good oil? Ive been a big fan of Chevron products, they always work quite well. I purchase this oil from Costco by the case.
Ive read many things.. i know it used to be the favorite back in the day around here but is the formulation still good? Is Mobil Super or Castrol GTX a better option? And are there differences in formulation from 5W-30 or 10W-30. Im trying to decide on switching to Delo 400 XLE Synblend 10W-30 but afraid of using a diesel oil in my Toyota.
