Anyone using Motorcraft 5W30 full synthetic in the Ecoboost. Got 3500 on the clock and considering changing over.

found out that it has a slightly higher flash point and the same pour point as Mobil 1. I got the spec sheet off of Motorcraft web site.

Well if it's going to perform as well as Mobil 1 why not use it? If there is a warranty concern, it'll be kinda hard for Ford to fault the motor oil - hell, it's their recommended stuff!

It's in my Platinum EB right now and that is the quietest engine I've heard in a while. Drove the truck from Houston to Arizona with no problems what so ever.

Good stuff!

Also, I have a post about Ford's switch up on filters here:

full synthetic ain't ford's recommended stuff- it's there brand but not recommended for the ecoboost. The engineer on one of the chats said to use 5w-30 synthetic blend not full synthetic

got_titan

wonder why the engineer would recommend a blend when a full synthetic is supposed to be superior in every way?

HogFan

Seems full synthetic would be superior, especially that it has the higher flash point and the heat associated with a turbo motor; however, I am certainly no engineer? I plan to go to the dealer this week for oil change and I am going to have them call the tech hot line to see what Ford's position is on full synthetic

If my turbos are glowing red, semi synthetic ain't gonna cut it! If you really want to figure out the ideal oil for an Ecoboost engine, it would be something rated HTO-06; that is the Honda/Acura spec developed by them to keep the turbo engined Acuras in top shape for life. It's not easy to meet; only 5W-30 Mobil 1 and 5W-30 Pennzoil Platinum (and Pennzoil Ultra) meet it.

Next time you're at Walmart or the auto parts store, check out who meets HTO-06; only the three above do.
I used the Pennzoil Platinum in my Mazdaspeed 3 mainly because it held up better to the fuel dilution issues those engines have. It worked out fantastic in my Mazda, and I'd use it in my EB, but for warranty purposes I'm going to run the Motorcraft full syn.

You'll notice that the Full synthetic 5W-30 is described as "top quality" by Ford; now look at the Semi synthetic, it is described as "premium quality".

Top quality oil is all my engines see, from my 2 EB trucks right down to my 4 stroke Honda weedwacker.

I can't think of the last time I used a conventional oil or a blend......

I want whatever they used in 448AA

After the hero engine teardown:

"Why the EcoBoost engine was so clean
The comparative lack of engine sludge/grime indicates that the engine’s PCV (positive crankcase ventilation) system and the recommended Motorcraft 5W-30 synthetic blend motor oil – available off the shelf – worked in harmony to contribute to clean engine operation. "

Looks like the hero used synthetic blend.

I wonder what the oil change intervals were with the hero engine. The only reason I hesitate to use the MC blend is some pictures I saw on bobistheoilguy indicating quite a bit of varnish on a 4.6 mustang. IIRC he was doing 7.5 k mile OCI's.

Good to know that the MC blend can handle what the EB dishes out! I think I'll still stay with the full synthetic though....

I think they are recommending the blend to show you don't have to go the the expense of a full synthetic to get those results. They also recommend 87 fuel. In either case you can use the recommended fuel or oil, or you can get better performance by using the top grades.
