Wolfshead Univ Syn ATF or Mobil 1 ATF?

[qdeezie]

Looking for some opinions here:

Vehicle – 1990 F150 / 5.0L V8
Transmission – E4OD

Looking to change my ATF over to Synthetic ATF. Currently, I have done 2 fluid cycles with conventional ATF. The first was with Accel D/M ATF and currently I am running Supertech D/M ATF. My transmission shifts fine, but I truly feel like it could shift smoother and also I’m doing this as part of my complete synthetic driveline fluid upgrade. Syn is going in the engine, trans and diff.

Just as an FYI for those that are curious, the motor oil I will be using is 5w30 PU and the gear oil will be Amsoil Severe Gear 75w-90 (SVG). I’m currently getting 17 to 17.5 MPG with my current combination (Pennzoil Hi Mi 5w30, ST D/M ATF and ST 75w-90) and looking to boost my gas mileage as well with the upgrade. I’ve done a few upgrades to the ignition system, so that’s probably why I get more than the 15-16 mpg that I’ve read that my truck supposedly got from the factory.

My ATF choices on the table are:
1) Mobil 1 Synthetic ATF – With the AAP online coupons, this suddenly becomes a very cheap and affordable option. Also, since my vehicle uses more than 12 quarts of fluid, the availability of that extra 1 to 2 quarts of fluid is there without me having to go above the call of duty to find those one or 2 quarts is a factor in perhaps purchasing this.

2) Wolfshead Universal Synthetic ATF – I can get a case of this very cheap from amaliestore.com, however, since the case only contains 12 quarts of fluid, I really think that it might be a challenge trying to find someone in my area that sells this fluid by the quart. This is the one that I originally wanted to use, but the fact that I need more than 12 quarts and being unable to find that extra 1 to 2 quarts somewhere relatively local, that might be a problem. If I could even find it in any city on I-85 between Charlotte, NC and the NC/VA border I’d definitely swing through and pick it up because I travel that route quite often.

Does anyone have any experience with either of these ATFs in an E4OD transmission?

In general, what are your thoughts? I’m trying to be one and done for 50K miles or more regarding ATF.

I can speak on the Wolf's Head. In fact I was debating the use of 15w40 in my 7.3 powerstroke.

My friend is a professional transmission rebuilder, we have used many brands of fluids. The Wolf's Head performs very well in the E4OD's and newer 4R100's we use quite a bit of it with no problems. I am not sure how long ago your rebuild if any was done on your trans. I would just caution you that changing fluids on something that was neglected if it was may cause you problems.

Run Wolf's Head ATF with confidence.

We use the Wolf's Head Universal synthetic on our farm in our trucks that have Allison transmissions and it works really well. We buy it by the 55 gallon drum and it is the most affordable we've been able to find so that's a big thing for us. However, in your case, since you're using such a limited amount, I think you'd be better off using the Mobil 1 since it is more readily available in small quantities.

Although I'm not using it in a truck, I am using the Wolfs Head Universal Synthetic ATF in my 02 Lincoln Continental.

I purchased the stuff for much less than other Synthetics, and I've done the "Pump & Dump" first at 50K and again at 80K. It works great. No problems. (86K now on the clock)

Co worker just dropped some in her s 10 blazer, no issues at all. She said so far the the WH makes shifts a near night an day difference...I'm thinking that is a good thing.

Mobil 1 ATF has worked very well for me for many years in Fords.

Thanks everyone for the feedback. I'll think on it and let everyone know what direction I decided to go in. Both should be a significant upgrade over ST D/M ATF.

The one item that concerns me is this fluid also claims to be suitable for CVT's

In mainstream multi-vehicle ATF's such as AMSOIL and Maxlife, CVT's are specifically excluded. Makes me wonder about the validity of their claim pretty much "good for everything"

From what I gather CVT's are very particular about coefficient of friction requirements and thus multi-vehicle formulas don't meet these requirements.

With the AAP coupons, Mobil 1 is an easy choice. M1 has gotten expensive.

Amalie/Xcel/Wolfhead is sometimes available in the smaller mom/pop auto parts stores. You can email Amalie for location availability. Its also cheap enough to buy 2 cases and save the rest for drain/refills, future maintenance, or sell to neighbors/friends/craigslist/ebay/here!
