Motorcraft does offer a full synthetic but I do not believe that is what the factory puts in these cars.

Mobil 1 is a Base 3 POA which is not a full synthetic oil. Anything at a POA 4-5 is a fully synthetic motor oil. Mobil is advertised as full synthetic due to its great ability to protect against wear. I read an article in DSport magazine that I still have at home, that did a HUGE detailed review on motor oil in general. I typed out the entire article over on Corvetteforum. I will copy it here in a new thread. Stay tuned

How much do these cost?

I did my 1st oil change at 5000 miles and went to Mobil 1. I plan to get 7500-8000 miles out of this oil ( manual and oil monitor show it can go 10k miles between oil changes). I will get a report done at the next change. Should be early August.

I think it was about $25, I had my wife send it in for me since I'm out of town. The TBN is a little extra. There are lots of other places that do the tests though, prices might vary.

The term 'full synthetic' has become a misnomer since there is no universally accepted definition. It's now become a throw-around term for oil made with Group III, IV, or V base.

Back from the dead but here's my 8200 mile Royal Purple 5w-30 analysis

**GTOphil** · 02-11-2014, 10:20 PM

I use Mobil-1 5w20

Pennzoil Synthetic Blend 5w30 in our truck.

Both PER Ford specs.

Pennzoil ultra. Hard to beat.

Yep, multiple test have shown Pennzoil Ultra to basically be the top "of the shelf oil" you can buy. It beats Royal purple and Mobile 1 extended. Still can't hang with Amsoil, but its not on shelves.

Looks like that's about the limit.

I switched to Motorcraft 5W30 when I did this oil change. I may or may not do another UOA when I have it changed according to the oil life monitor. Since Don Davis Ford does a change with filter for $32, I can live with the findings.

Very interesting in seeing results.

**DirtyD** · 03-10-2014, 09:33 AM

My current oil change is going to be my last time running the Motorcraft Synth blend 5W-20. I plan to do a UOA and see how the car has done on this oil for 42k miles, then the Amsoil 5W-20 full synth goes in.
