We have all seen it. Somebody with a fl820 filter and 5 or more qts of 20w50. The filters tell me that its for a 4.6 or 5.4 ford that is specked for 5w30 or 5w20.
If you mention to them that they have the wrong oil for that engine they tell you that your stupid and that they are smarter than the engineer that designed the engine.
