What oil are you using?

[Coyotestang13]

Well that's comforting to know - particularly considering how car salesmen encourage their customers to beat the crap out of a new Mustang on the test drive. On one Mustang PP I test drove recently (car had 40 mi on the clock), the salesman bragged that a previous customer (a young Marine) got that car up to 110 mph on his test drive (hopefully the Marine got the engine up to operating temp before he dropped the hammer).

It would be great if the person doing that kind of driving actually intended on buying the car. Sales staff shouldn't be allowing that kind of behavior in the first place.

My local Farm and Fleet sells AMSoil and hopefully they carry this 5w50.

I have been using Amsoil full synthetic OE oil. Good stuff

 

[VTECSAUCE]

why are ppl using different oil weights than what is suggested?

Anybody using Motorcraft's 5W20 ? Is it any good ? And who really makes it ?

Any idea why Ford recommends synthetic blend one and full synthetic is listed as optional ?

Conocco Phillips makes it. They were the lowest bidder.

I'm using Pennzoil Platinum 5W-30 in my '15 EcoBoost. I used Mobil 1 Extended Performance in my previous daily driver (Nissan 350Z), but thought I'd try an oil using Shell's new gas-to-liquid (GTL) base stock.

From what little I know:

If you look at a bottle of Motorcraft Full Synthetic, it says on the back: Product of Korea. Blended and Packaged in the U.S.A.

ConocoPhillips blends and packages the MC Full Syn. The base stock I believe is made by a South Korean refiner and is known as S-Oil Ultra. It is a premium group III+ base stock that performs in many parameters close to a Group IV PAO base stock. It's good stuff. S-Oil Ultra is sold to around 33 markets world-wide. Phillips has exclusive sales and distribution rights of S-OIL Ultra base stock in North America. Companies like AMSOIL and Joe Gibbs Driven oils do not, I think, drill/extract and refine their own base oils. I wouldn't be in the least surprised if both these performance oils are built on S-Oil Ultra. Nor do those companies make their own additive packs. These are put together by specialist companies like Infineum and Afton Chemicals, which together probably have 90% of the market share. The advantage many car mfrs have, in working with their lube partners (e.g. Ford-ConocoPhillips, BMW-Shell, and the line of Castrol Professional oils sold only through car dealers) is that the lube partners can tailor the add packs and overall blends to the particular engines or families of engines made by the auto maker. These oils are often formulated as a team effort by the auto maker's engine development engineers and the lube maker's tribologists and chemists.

So I would not dismiss any of the Motorcraft oils as being inferior products.

I would love to provide a link or source for this info. Much of it comes from a video presentation, called Slippery Secrets, done by a chemist from Afton Chemicals at a professional seminar some years ago, but the link has disappeared.

I would have liked to see how many would have selected the MFG Recommended Motorcraft 5-20 Synthetic Blend listed as an option.

I believe the MC syn blend is the factory fill on the '15 GT v8. It apparently does very well if this uoa is representative: http://www.mustang6g.com/forums/showpost.php?p=592635&postcount=161. That is a great report for the factory fill.

Royal purple for me

I switched to Amsoil 0w-30 and Amsoil filter in my 2013 and it developed the dreaded tick immediately after the change. Not sure if I will go with. Amsoil again or not. Mobil 1 5w-30 gave me no problems.

Penzoil platinum 5w30 great reviews on bitog sold me.
