So for changing my oil in my massey gc1715 . . . Instead of using my Havoline favorite . . there a real reason to use a "diesel motor oil" ??

I'm not saying I dont believe it . . But its a little hard to swallow as many years as I've been around oils.

I'll do some checking on it. At least Castrol is my second favorite brand aftet Havoline. Lol

Is this about the old "Pennsylvania grade" motor oils? (Amalie, Pennzoil, Quaker State, Kendal) Don't know about now but there was a time when a paraffin based oil was a superior lubricant to a shale based oil. As long as it was changed at routine intervals and the engines operated within proper temperatures they offered superior service. But - If you rarely change your oil &/or filter or encounter a blown radiator hose/stuck thermostat...and your engine overheated it could "asphalt" your engine. It happened enough that some folks blamed it on the motor oil. (Couldn't be their fault could it?)

Since I plan on changing regularly and plan on operating with a sound radiator & hoses I still prefer Pennzoil. When on sale, or the only one available in the weight or grade I needed I've purchased Havoline. No problems with it.

Greetings Clay. You're partially correct, as the Pennsylvania oilsyou named did have a rather high parafin content to them. However since "the old joe" Texas well that started things and its many since . . they were not "shale oil". West Texas Intermediate has been the measurement standard for oil markets for near a hundred years because of its quality and chemical/content consistency.

And while a high content parafin oil is a good surface lubricant . . . the heated parafin used to collect in oil pans causing considerable buildup in the pans. The consistency of regular oil changes didn't cure or remedy that issue. Any mechanic could identify the oil region used in the vehicle by the look on the inside of the oil pan.

By the way . . shale oil is also a high quality oil and in some location cases coming from the Dakotas, it is much superior to WTI oil. But shale oil is found in certain pennsylvania and east coast areas as well as Oklahoma, the Dakotas and Colarado, some areas of Texas, New Mexico, Kansas, etc..

And Havoline at one time was considered "the premium" WTI oil.

Axle,

I never had a parafin buildup in any oil pan on any engine I've ever owned. I've also spent a little time in the oilfield and have witnessed wells that produced parafins that would continuously clog up and need a hot oil truck or two or three come out and clear them. Parafin-scraper cups would be used to swab the well in.

The refiners prepare the crude for various markets. Other than a little distillates I never saw anything come out of a well that looked ready-to-go to market.

Greetings Clay. I never had a parafin build up in any of my oil pans either . . . Likely because I used engine flush once a year with one of my oil changes, or oil treatment additives, or texas based oils. But I've certainly seen buildups in others pans . . some of them quite considerable.

And as you mentioned, oil comes out of wells in many different levels of sour and sweet and light or heavy consistencies. But in non-shale oils there certainly are differences in eastern coast wells as compared to southwest or midwestern wells.

Here in Texas during that time you could tell who used the "Pennsylvania grade motor oils" when you dropped an oil pan, or pulled valve covers off. That oil was some nasty stuff.
