I see Walmart stores always have the Mobile 5000 regular oil not a synthetic, the price is a few dollars lower yet the claims are fantastic about the 5000 oil change intervals at 5000 miles.
is this mobile 5000 oil as good as oil to use as compared to Valvoline , Pennzoil or Castrol in a 10x30 weight ?
