2004 F150 Lariat - 37,800 Miles - Have used Royal Purple 5w20 since 15k miles. Used Mobil 1 0w20 before. Absolutely no problems and will continue using Royal Purple
1998 F150 Lariat - 230,000 Miles - Have used Mobil 1 5w30 for the majority of the miles, switched to Royal Purple for the last two oil changes.
Both trucks continue to run great with no signs of oil consumption.
