I use the Castrol Edge EP 5W30 in my Tundra and in my son's Elantra. He commutes 140 miles a day so even at a a standard 7,500 mile oil change is easy to miss one. That would require an oil change every 10 weeks. Does 15K intervals in the Elantra with Edge EP and there have been no issues. Could probably do 20,000 like the oil is guaranteed for but I cannot find an oil filter good for 20,000 miles.
My Tundra has 157K miles and does not burn a drop of oil between oil changes. The dipstick reads Full right before I change it. For that I use a 10,000 mile oil change and a Wix 1515 or Napa Gold 51515 oil filter.
