Nope, I stockpiled on the Rotella T6 for two more oil change.
la_fx35, have you made the switch to royal purple yet? I might also have to try it too. 1000 miles into my oil change with Rotella T6 i had to add almost a quart in. I might just have to give royal purple a try on the next one. rather pay more for the oil up front than always adding more in.
