transmission fluid mt6

[UnleashedBeast]

Damnit now I have to buy some.

Might as well sign up as a preferred customer and get anything you buy from Amsoil at dealer/wholesale cost.

Preferred Customer

I'm already signed up, I ran amsoil in my 08. :thumbsup:

Picked up 3 qts including tax for $40.36 at a local auto parts store. Fanatastic price compared to the $87 plus tax for the DCT if I would have changed it myself. And from this experience I will never put conventional oil in any new car to save a few dollars either. Even if it's my wife's car lol.

 

[UnleashedBeast]

The only cars I EVER use conventional oil in are the beaters, and that's only if they are leaking. I will then use cheaper high mileage formulations for the added seal conditioners. Other than that, I'm a true 100% synthetic guy....not the highly refined petroleum commonly found in bottles marked "synthetic" on the parts store and Wal Mart shelves.

 

[Rob72]

^ I have a 130,000+ mile crapalier that I used a high milage 10W30 in also.

MTG is my fluid of choice for the MT82

Yea, I actually think the gear whine has gone down since the fluid swap. When I first put the fluid in I could tell a slight difference but on my way home after my car sat for a while the shifts were 100% better and the temp was 48* i think. 2nd gear is still a bit crunchy, but not near as bad. Every shift seems to go into the gates a lot better. The shifter seems to center itself a lot better also. WOT shifts are improved. I definitely recommend doing the swap to anyone who is skeptical. However, do not buy the crappy pump from advanced auto zone. It sucks. :/

 

[UnleashedBeast]

I know what you mean about the pump. Ironically.....my favorite pump to use is easily found at Wal Mart. I use it for everything lubrication replacement.

Heh, nah it broke. Had to go back to the autoparts store and grab a new one. I brought it back to them and they replaced it though, heh. Good for them.

Live and learn. Never would have thought wally world had that.

I wonder how MTG compares to MTL. I have been running MTL since June..

Engine oil is still used to hold the cam phasers in position. Wondering if using a thinner oil has any negatives effects on this.

When I spoke to two calibration engineers (one Ford and another Ford Racing) who worked on the 5.0L engine in the BOSS and BOSS 302R, I was told not to deviate from the factory recommended oil viscosity. They said that if you deviate much from the factory recommended viscosity, the TiVCT system would struggle to find its sweet spot, if you will, and the engine will be down in power a few HP/trq. The new CTA (camshaft-torque activated) VCT system still sorta relies on viscosity via flow rate in and out of the intake/exhaust orifices of the CTA VCT actuators.

Please keep in mind that the Mustang V6 and GT have different oil viscosity recommendations than the BOSS 302 and BOSS 302S/R (5w-20 vs. 5w-50). The BOSS (RoadRunner) calibration, of course, is not the same as the GT (Coyote).

More on topic with this thread, I have had MTL in for 7,000+ miles now and shifting is much better than the XT-M5-QS. Shift quality immediately improved after switching over. Shifting then got better a little bit more through the first 1,000 miles of use and then kinda plateaued.

That is the nuttiest thing I have ever heard. I have had my car on the dyno with 5-20 and 10-30....there was 0 difference in power.

^this!

Not to mention, the recommended lubricant for the Boss, Motorcraft 5W-50, shears to a light 40 grade/heavy 30 grade after 2,000 miles. What then? A Boss owners begins to have engine trouble because the oil has sheared from 19.9 cSt @ 100*F down to 12.5 to 13.5 cSt @ 100*F?

I think not.

Sadly a lot of engineers are stuck on how it works on paper and theory of operation.

All of this.

 

[UnleashedBeast]

I just noticed that I put this.

19.9 cSt @ 100*F down to 12.5 to 13.5 cSt @ 100*F

when I should have put this

19.9 cSt @ 100*C down to 12.5 to 13.5 cSt @ 100*C

Darn metric system...oops...lol

Got any data to back this up?

I'm not saying your wrong, it's just that the internet can be a place with too little objective/factual backing. Plus, I'd like to see what is and what really isn't. I didn't work on the calibration, nor was I around to see anything that was done, so what I was told is just that - what I was told.

I mean, like the other guys stated, the oil is going to break down some and, depending upon the quality, sooner than others; thus possibly allowing various affects. So was the tuning done based on, say 5w-20, at a less than optimum life, like 40-50% life? Was it done with the oil at 20% life? Was it done at 80% life? Maybe the calibration engineers really didn't know what they were talking about and the TiVCT adaptability can properly compensate? Who knows, but the data could help clarify.

For example, Ford claims 305 HP at the crank for the 3.7L, so I would assume, to save face in case someone wanted to make a case out of it, that projected power rating was under less-than-par circumstances.

So you are going to say my word is less over the Internet vs. some guy you spoke with who doesn't have anything to back his info up with?

Anywho, the following dyno runs were done with 5w-20:

The runs were done this past March. I switched over to e85 in August and did some more dyno work to tune the car for the fuel change. (I had switched over to 10w30 before making the switch on fuels.) We baselined the car before making any tune changes and the power numbers were near identical. All-in-all after making tune changes running e85, we picked up a few extra HP due to the extra timing we introduced. I did not capture the run files unfortunately.

Bottom line, the small difference in oil viscosity comparing 5w-20 to 10w-30 has no impact on HP.

BTW - I ran my best 1/4 mile times running 10w-30.

We are talking trans oil, not engine. Take that shit to a new thread.

I've got Amsoil on the way. RP didn't change one thing.

I think we should continue the engine oil discussion in this thread just to piss you off further.

Take your brash attitude and shove it up your ass.
