I understand my 7.3 uses the engine oil to operate the injectors, and is effected by dirty oil. My oreilly store has 15-50 Mystik blend for 12.50 a gallon. The recommended weight is 15-40. Would the 15-50 in a warm climate(SoCal) work, or are my stock injectors too sensitive and going to malfunction? Thanks. (I'd buy Mystik 15-40 blend if they had it, but only 15-50).
