next door neighbor worked as engineer for ford for 15 years before moving to az to work for intel... he says that choice of brand has little to no bearing on thermal capacity or long-term engine reliability and that weight and viscosity are the key parameters... he claims that ford tested this for years and that was the conclusion every single time... just figured i'd share that - personally, i have no technical opinion... i'll prob just go mobil 1, b/c i used to work at mobil oil way back when
