I returned the motorcraft and got a WIX filter, the guy said that one will do and I didn't feel like spending $13 on one of the highend ones. lol

I prefer using Mobil 1 which from the latest info. I get is still a group 4 synthetic and Pennsoil a group 3 like castrol syntec.

What exactly does the dealership put in our rides? At my first change I asked the tech who said it was synthetic, but then I thought someone here said they use a blend at the dealership. Anyone know what they (dealership) uses? If so didn't OP already have synthetic?

Manual says oil change is due every 5K which leads to believe they're using a blend. Regardless, I'm using full synthetic Mobil 1 with an extended life oil filter.

or use a new Motorcraft FL820S filter and change it halfway through the oil change cycle. New filter, less cost buying 2 filters than 1 expensive one and Mobil 1 always seems to evaporate a little in all the Fords I've ever owned. Besides, adding a quart of new oil halfway has to help when you're going 8-10K between changes.

Our cars come with blend. After that, lord knows WHAT the dealer is putting in, assuming you don't like to get your hands dirty and you don't do your own oil and filter changes.


"Evaporate"? More like a typical Ford engine using oil. Adding 1 quart to top off after a filter change midway thru the oil change adds a ~16% volume of new oil to what's in the crankcase; not what I'd call mind boggling. If you're not going beyond 8,000 miles, the Motorcraft filter can easily handle that much in-service mileage. And all of my previous oil analysis training has shown that, unless you already have something wrong with your engine, synthetic is good beyond 10,000 miles.

I've used FULL synthetic since 1976 and just started using Mobil 1 filters 6 years ago and change oil and filter every 10,000. We put 150,00+ on our cars and get the same mpg when bought new. Always has been Mobil 1 oil too. Not all Full synthetic brands are the same, either. I just prefer synthetic oil as runs cooler and gets up into the upper cylinders much quicker in -20F coupled with having to change less often. Comments welcome

I thought the 'evaporate' part was BS also until I started looking into it, and it seems like it's Mobil 1 that's the biggest culprit. I was reading about the guys using Amzoil and running 15K+ miles without an oil change. They would swap out their filter halfway through and of course would have to add nearly a quart that the filter held.

Interesting reading, even if it is Amzoil propaganda;

NOACK Volatility
The NOACK Volatility Test determines the evaporation loss of lubricants in high-temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy, increased oil consumption and excessive wear and emissions. A maximum of 15 percent evaporation loss is allowable to meet the API SL and ILSAC GF-3 specifications. As shown in the graph, AMSOIL 5W-30 Synthetic Motor Oil lost an extremely low 4.9 percent of its original weight during high-temperature service, maintaining its superior protective and performance qualities, while Mobil 1 Super Syn 5W-30 Motor Oil lost 9.17 percent of its original weight.

Yea, bookmarked for sure....

I will never let him live that one down
There is a picture of me in a post somewhere.
Can anyone dig that up?
