Mobil delvac 1, red line , I'm scared to say that -Amsoil ,in Canada Esso XD-3 0W40., Shell rotella 0w40 ( not available in Usa ), for gas engines there is more choice but I dno't know if you interest in that , Actually Castrol has full gr IV synthetic on tha market in the 0W30 weight ,it must say on the back of the bottle made in germany, I ran this oil in my modified turbo volvo 850 and got excellent UOA report much better that I expected , I woul recomend this oil to any turbo appilcation beacouse it does not shear down at all

I am a Mobil 1 fan. Have run it in my last 6 autos. One of them for 235,000 miles. Changed the filter every 5,000, changed the oil every 40,000. Never had a problem with any vehicle. Plus they ran a little cooler and in Montana they started a lot easier in the winter. I called Mobil engineerimnt to get their recommendations for engine, transmission and differentials. I changed my 1999 F25 to Mobil 1 after I bought. It appears that I may have gained approximately a mile per gallon increase. I use NAPA gold filters ( I understand that they are made by Wix). I base this choice on my brothers recommendatrion that either one of those filters are extremely good. His information is based on 40 years in the automotive parts business. I also noticed on my son's F250 (which was serviced at a Ford garage) that they used a NAPA gold. This is for what is is worth, I am retired and not selling anything.

"14. IS DELVAC 1 100% SYNTHETIC?
Yes. The base stocks for Delvac 1 is a 100 percent synthetic oil. The base stocks used in blending Delvac 1 are all "chemically constructed" instead of being simply segregated out of crude oil-like conventional mineral oils. This is exclusive of a small amount of mineral carrier oils used in the additives. "
Since GroupIII synthetics are hydroprocessed or hydrocracked and not "chemically structured" like PAO's from Ethylene gas, FAQ number 14 rules out the Group III idea."
Further on, FAQ#16 goes on with a question about groupIII oils:
"16. I HAVE BEEN HEARING ABOUT NEW BASE STOCK TECHNOLOGY CALLED HYDROCRACKING OR HYDROPROCESSING THAT IS SUPPOSED TO PROVIDE SYNTHETIC PERFORMANCE AT CONVENTIONAL OIL PROCESS. WHAT CAN YOU TELL ME ABOUT
THIS?
Hydroprocessing is a term which refers to a manner in which lube base stocks are made. A wide quality range of base stocks can, and are, produced by hydroprocessing. The majority of hydroprocessed base stocks, produced today for the most part, are equivalent to conventionally-refined stocks. Although hydroprocessing does offer the potential to provide better performance than conventional stocks, in some applications they do not equal the performance of synthetics. In fact, what is most important is not the differences in the base stocks themselves, but rather the performance of the finished lube oil using these stocks. In this regard, we are unaware of any product on the market containing conventional, hydroprocessed, or any other stock that matches the superior performance of fully-synthetic Mobil Delvac 1<SUP>®</SUP>. The performance requirements for a premium engine oil in current engines involve a wide range of criteria, including:

I hope that clarifies things based on the link provided by you.

well good, based on that i would have to agree it is a full syn, which i thought in the first place. then someone had said it was a dino based oil, so i did some more looking around and saw that statment that it was "dirived from crude oil". after reading those FAQ's on that site, i am back to believing its a full syn and will keep using it. wpheeeew,

I changed out my dino based oil for Mobil1 Delvac 5/40 two days ago after reading this thread. The difference is like night and day. MUCH quieter operation. I don't think that I will push out the mileage to the numbers that some people have here, I am just too old school. And oil's cheap compared to an engine. But I really like the nice quiet operation in the morning. It used to really clatter when cold. And romp-romp-romp if you let out on the clutch to get going. Now it's just smooth.
