Changing differential Fluid...
#6
I have royale purple in the motor, tranny, power steering, and differential. It's worth it. Horsepower TV showed and SS (Super Sux) on there and they swapped everyhthing out and gained around 10HP to the wheels. I had to see it to believe it.

RP is good stuff. I'd use it and that says a lot to people that know me. I use Redline Light Shockproof synthetic. It's a personal choice but, I'd just as soon use RP. What you should get is a 4oz bottle of equa-torque.
I like shockproof gear oils for mustangs because of the number of clutch drop burnouts I see that involve them. If you don't do drag racing or burn-outs or anything really aggressive, then regular synthetic GL-5 is fine.
FWIW, I've had the fortune to open a couple thousand differential inspection covers back in the day as part of my job. The one thing I noticed was that the insides of the carriers on synthetic running diffs were lots cleaner than those that filled with conventional GL-5. No other difference was noticable to me.

have you ever come across such a fluid labelled as GL5? Just curious... in 15 years I've never come across a GL5 marked fluid that you couldn't use in combination with equa torque. I'd like to know if there's one out there that I've not seen yet.
Does anyone know if something like Lucas Oil treatment is compatible with GL5 for such a purpose? The huge film strength of that stuff suggests to me that it'd be nice for gearboxes.

On top of that, this was purchased under my friends employee pricing...
Gotta love Genuine ford pricing...

<hearsay>Royal purple is blended in small batches with a high degree of accuracy but from my reading on the subject it seems that they don't have a standard "formula" in that one batch to another may use different amounts of each substance/ingredient. </hearsay>
Most commercially manufactured gear lube (hell most any petro-chemical) is made in usually very large batches using a fixed formula. There are different reasons for both methods but they come down to the same result, repeatability. Royal Purple has a different audience than gas-station-brand and those people are usually more interested in edge-of-the-envelope performance than standard service performance.
I like redline light shockproof and heavy shockproof for rear ends but that's a personal preference based on how I set up and use my car. I would use synthetic over a conventional any day because of the greater stability potential of synthetics and normally better thermal properties.
From what I remember Ford started spec'ing synthetic gear oils in the diffs at least a decade ago. Given that they specify synthetics, I'd stay with it. I'm sure they figured out that a conventional wouldn't do what they wanted or they'd have stayed with it since synthetic is so much more expensive.
