It's all backwards compatible. Ford likes a panic every couple decades. I remember their panic in the first year or two of the 7.3 L Powerstroke over foaming.
How does the contamination of the engine oil from injector lubricants compare to the contamination from Low Sulfur Diesel (1993) and can the current formulation of Diesel engine oils resist the oil contamination from injector lubricants?
When I write injector lubricants, I refer to Stanadyne injector lubricants, for example. What about contamination from 2-cycle oil being used as an injector lubricant?
