Oil change time

[Boosting Stangs]

The issue I see with this discussion is that the recommended Motorcraft oil (5W-30) is a GF-5 oil. Amazon sells it for 12.60 a quart! Ouch.

Anyway, Mobil 1 5W-30 is GF-5 certified but Shell T6 5W-40 is NOT (this is for diesel engines). I know that some are saying they have used it with good results on other cars but putting a non-GF-5 oil in the Ecoboost when Ford specifically recommends it seems like a lot bigger issue than what oil filter one chooses. Just say'n. Be careful!

Nothing but GF-5 oil for gasoline engines will be going in my car.

No disrespect, however, trusting anything the API or ACC require to be certified to a grade like GF-5 is ludicrous. These are PAC foundation lobbyist buying out politicians for favorable deals, selling the consumer a false and fake sense of security. It's really just protectionism or strong arm tactics.

It really falls to this point, everyone here is modifying their power plants to exceed the manufacture recommended and preset parameters. This will create stress causing higher engine temps. Thus needing a slightly higher weight oil to combat "oil sheer", especially in turbo charged motors where heat is a concern.

Well that said i now have a question. ..

So i had my oild changed today, rotella t6 like i said, wix filter, and a set of ngk plugs, at .028. I have the accessport with the 93 oct tune flashed in there. So prior to the oil change, wot street pulls kept the af ratio steady at 11.6, now post oil and sparks af ratio is 11-10.9...and this is consistant. The car according to the mighty butt dyno feels better, and richer i gather is better but...
What should i think about all this?

hey i understand but im pretty desperate here, and it kills me further that I cant get the stuff you have in stock first cause ryan told me it would be cost prohibitive. Do you have maybe like an exact day youll have them? order was placed on the 24th

Also, i bought the accessport through you guys, im interested in the economy tune (my buddy has it). he has a slew of bolt ons and last week we got an amazing 34mpg on a 2 hour trip!!!
Also do you have a better tune for stock than the one that comes with the cobb for 93oct? I can feel the bump but Im certain it can be better. Also when i get the intake, intercooler and pipes, do you have a tune for that?

And thanks but I found the plugs locally. theyre going in tomorow with my rotella oil/wix change

You should already have the economy tune, if you're using the Cobb tune. Adam supplies his OTS map with the Accessport (if purchased from MAP), so it'd be worth checking with him directly about. I'd suggest PM'ing him about that.

Also, the Cobb map has 5-way map switching enabled. Make sure that the cruise control is turned off, then press the 'Cancel' switch on the cruise controls. The rpm needle will jump up to whichever slot you're currently in. Slot 1 (1,000 rpms) is the high performance tune. Slot 5 (5,000 rpms) is the economy tune. You switch up and down through the slots by pressing the + and - buttons on the cruise controls right after you press cancel and the needle jumps to the active slot. Slots 2-4 step down in performance from Slot 1. Slot 2 is more of a high-medium performance tune whereas Slot 3 is more of a medium performance tune. Those step down like that until you get to the Economy tune in Slot 5.

Here's some reading info on that: https://cobb.box.com/mustang-ecoboost-map-notes

also does your catted downpipe use ceramic or metal substrate? Im deadly afraid of the complete exhaust system, I cant have another loud 4 cylinder in my life, Id really like a almost stock sounding 3 inch exhaust. Ive gone so far as to consider getting the downpipe and the midpipe but leaving the stock mufflers:frusty:

I ran a catless downpipe on the stock CBE for a while, and other than a little add of added turbo whistling noise, the exhaust was as quiet as stock. I believe Adam said that their catted downpipes utilize a metallic substrate inside of them. Again, that'd be a good thing to ask him within a PM though.

I'd make sure that you didn't accidentally get changed to a different map slot (see above). Spark plugs and oil in no way should affect your AFR ratio. That's set and determined by the values in your tune. 11.6-11.7 is correct for the Slot 1 High Performance tune, so you might be in a lower slot. I'd check that first.

EcoBoost engines do like to be run a little on the richer side, usually 11.4-11.7, but being low 11s isn't going to hurt it. Usually the tunes safely lean it out to 11.6-11.7 because it'll make slightly more power being a little bit leaner (within reason and safety limits).

Of its in there i certainly cant find it, theres the 93 and the 91 tune and thats it.
Ill check in a while what tune is loaded in there, but is there a tune thatll put me in 11-10.9? It just doesnt make sense to me, im definitely missing something here.
Im absolutely going with the downpipe, i dont think itll affect sound as much (i actually love the turbo whistle) what im worried about is going full catback...how does that sound? I mean ive heard the clips but i cant judge based on that. Can you have a nirmal conversation sitting in the car at idle? Will it wake up neighbors when i drive by? Will it turn the heads of black and blues? I just cant deal with that again..

The Economy tune (in Slot 5) might richen it up a bit, but I've never paid attention to it that much in Economy. When you flash the 93 tune, it contains 5 different settings per se within that tune. Those 5 settings found within the slots (1-5) will change things such as boost level, ignition timing, etc. So, it's very possible that it could also change the AFR too, but I just haven't paid attention to Slots 2-5 in that respect. Adam could probably answer that question more specifically.

I have a catless downpipe, resonator delete, and Magnaflows replacing the factory mufflers. At idle, it has a nice gurgle, but isn't loud. At 60 mph with the cruise set, I barely hear it. When you give it moderate throttle, it'll wake up and produce some noise, but it's not deafeningly loud and intolerable. Even under WOT, I could still talk at normal levels and carry on a conversation. There's absolutely no drone either, so I'd imagine this would be close/similar to other CBE setups on the market.

I'll try to get Adam in here to answer your map questions.

IF you are running my tune Slot 5 is economy tune and it is leaner than stock. Unless you are datalogging your car you can't accurately see if your car is running rich. Changing the oil definitely won't effect your fuel command, map switching or other changes will. When you got a tune file from me you were given some instructions to datalog your car with certain parameters. If you are having any sort of issues or questions, please contact me directly via email. [email protected]

I can help straighten everything out for you.

You all have been awesome by the way, ill email adam in a while. I shouldnt be here during work jajaja

Found on another oil forum, here's Shell's "official" comment on running Rotella T6 in a gas engine with a cat. Obviously a non-catted DP wouldn't be an issue here.
Email from Shell follows:

Dear Sir,

You should always follow the viscosity recommendations in your owner's manual. Please note that Rotella oils are not recommended for gasoline vehicles with catalytic converters.

Best Regards,

Shell Technical"

I then asked them how this can be since T6 is API SM rated for gas engines. Here's what they said:

"The API SM specification does not address the use of catalytic converters. The ILSAC GF-4 / GF-5 specifications restrict the use of certain anti-wear additive systems. These can shorten the life of the converter as the car ages and begins to use oil. Because of the higher levels of the ZDDP additives in Rotella oils, they do not meet the ILSAC specifications and cannot be recommended for use in vehicles with catalytic converters.

Regards,

Shell Technical"

So basically is only an issue if the oil is getting past a seal/ring by the sounds of it.

That would be my take. Personally I run Pennzoil Ultra Platinum 5W-30 Full Synthetic in mine. Ran it for last 3 years in my Genesis Coupe 2.0 turbo with good results. Somewhat similar engines.

The problem I'd assume would be that the cat would mask most of that oil smoke. I'm definitely not an expert, but maybe T6 shouldn't be used unless you're catless?

On your next oil change smell your used oil. I am curious as have heard some complaints from other direct injected users that the used oil of Mobil 1 and Penzoil both smell like fuel which means they are getting diluted.

Edit: To clarify a bit better I have read that Mobil 1 and Penzoil do not stand up to fuel dilution as well as other oils out there. The dilution will cause reduced oil film strength and premature wear.
