We realize though that when Appalachian basin crude (which some refer to as Pennsylvania crude) goes through the intial stage of refining the pariffin is removed from the wax distillate component of the crude. This refining split leaves what is called a "neutral", or a lubricating component. The lubricating component is then further distilled and cracked to produce engine oil, grease and gear lubes, depending on the additive packages. The paraffin and wax is stripped out in the refining process. So, it would be hard to make candles out of it.
Appalachian basin crude is still highly desirable for a base stock.
Lots of cars over lots of years have used this base stock engine oil with no issues.
