Motorcraft's 5W30 "full synthetic" motor oil is probably not a real synthetic. There are no technical standards associated with the term so it can mean just about anything. More than likely it is like Castrol Syntec which is a Group III petroleum which is definitely better than Group II but still short of a Group IV true synthetic. If the engine is not burning oil, synthetics are definitely a plus. The available synthetics are Mobil 1, Amsoil, Redline, Eon, and SynLube. Choose one of them for a true synthetic.

Second generation is a group III oil and a very good one. Prior Motorcraft were blended PAO's and Esters from Conoco .
Conoco's Syncon was one great motor oil ! It would frag the FTIR if not calibrated for it :cool
Other real PAO based oils available over the counter are
Phillips Trop Artic 5/30
Shell 5/30 and 10/30
All under 5 bucks a quart

The base stocks that motor oils are blended from come in five groups that are industry standards.
I=traditional solvent refining, nearly obsolete but still number one in world wide production.
II=hydroprocessed for better purity and higher viscosity index, rapidly becoming dominant in the US market. "ISO-SYN" and "Purebase" are marketing names for group II.
III=similar technology as II, but longer, more expensive process, legally can be called synthetic. Most major brand and house brand sythetics are group III. Shell Helix Ultra is considered group III, but is made differently and is factory fill for Ferrari ($700 for an oil change)
IV=Poly Alpha Olefin, the traditional synthetic, still a hydrocarbon. Amsoil, Mobil 1 and Royal Purple are primarily PAO.
V=esters, the most exotic and expensive, made from alcohols processed with acids. Redline and NEO are ester-based.
Alklated Napthelenes are another type of synthetic hydrocarbon made by ExxonMobil and blended in Mobil 1. They wont admit that it fits the definition of group III.

Jim, good summary of the different groups. The way I understand the "all hydroprocessed" technology is that Group II and III are the exact same process. The difference being the temperature the furnace and catalyst is run at. That's how they can split the difference and get a Group II+. They can control the process to get whatever VI number is required. It's a 'cracking' or 'hydrocracking' process so it consumes hydrogen and some of the feedstock during the process. So to make a run of the higher VI Group III base stock, less product is yielded for each barrel of feedstock and mcf of hydrogen.

While I'm new to the forum, the guy that owns NEO is a fanatic for good stuff and builds a lot of custom racing oil for some of the middle budget Indy cars and such. Paul Baker at NEO (also Baker Precision Bearings) has been doing this a long time and doesn't blend for a price, just the best he can build.
