"I spoke with one tech who is using Delo synthetic and Rotella synthetic in his older Cats. He says diesels will use or burn some Delo between changes"
Rule number 1, never say "all." That said:
All piston engines (gas or diesel) use oil between changes. Whether it burns, leaks, blows by the rings/seals, or vaporizes depends on the engine and how it's operated.
If you understand how a lubricant is made, DELO 400 is already a semi-synthetic lubricant. Google "ISOSYN" technology. DELO 400 just doesn't meet the strict definition (word salad) that boutique synthetic oil manufacturers require the industry to adhere to. Consider synthetic water. Does it really matter if it comes from a cloud, combustion, or electrolysis? Or if it's "all natural" from a mountain spring? Nope, it doesn't. It's all good.
For the price, DELO and/or Rotella is hard to beat in any approved application. IMO, keep doing what you're doing. If you have issues, chances are it won't be because of the oil.
