The original Amsoil synthetic was a dibasic ester...if water or antifreeze got in the crankcase, one had to "shovel" the glop out. It was not fully agreeable with mineral-based engine oils. I do not know the most recent Amsoil chemistry, but I understand it is now fully compatible with refined petroleum products and with major oil company synthetics..
Fully synthetic engine oils from major oil companies now typically use pao (polyalfaolephin) base stocks - examples are Mobil 1 and Mobil Delvac 1 (made specifically for diesel engines). The pao products are all blendable with mineral-base lubes.
I have run Mobil Delvac 1 for 250,000 miles in 4 successive VW diesels with no wear problems, no major oil consumption and no cold start difficulties (did not use a block heater in any of the VWs). After the 2 dealer-inflicted "free" oil changes, I will be going to Mobil Delvac 1, 5W-40 in my recently-acquired 2014 CTD.
For technical questions on Mobil products you might call 1-800-ASK-MOBIL.
