Several have totally missed the point. It's not just motor oil! It is a man made synthetic that is formulated to be used in all the "holes" .
Been using it for over 25K miles now.
I don't see shavings on my drain plug. But, I been running mine for 15K before the MoCo said it was ok to do so. So, I'm only on my 2nd fill of Syn3 in my tranny!

Syn 3 is a Group 3 synthetic oil, meaning its made from crude oil outta the ground. It's considered synthetic 'cause Mobil lost a court case with Castrol, IIRC.

Syn 3 ain't a bad oil, there are just others that are better, and cost less to boot. The HD hype tends to tick me off. [8D]

Per your comments here, what do you see as the difficulty (if any) with Formula+ in the primary and tranny? From information I've gathered, both on this forum and others, Formula+ is straight 50 wt with additives (don't know which ones). Poll results show an almost even usage of SYN3 and Mobil 1, but I lean toward H-D but have had no problems in my car, track, or tractor with Mobil1 inc. their filters. Appreciate any comments you have. Sincere thanks.

Poll results show an almost even split between SYN3 and Mobil 1 75W90. But when I change next, in goes Mobil 1 75W90 to tranny. Motor oil just is too light for gears.
Motor oil and gear oil viscosity are measured using different methods. The 75w-90 gear oil is equivalent in viscosity to 10w-50 to 20w-50 motor oil.

10w thru mid range of 20w engine oil = 75w gear oil

Mid 20w thru mid 30w engine oil = 80w gear oil

Mid 30w thru low 40w engine oil = 85w gear oil

Low 40w thru 50w engine oil = 90w gear oil

60w up motor oil = 140w gear oil
Gear oil usually has additives, sulfur being one of 'em, that do good things with gears. Sulfur in a motor ain't a good thing. I don't know what the drawbacks to the new Formula+ stuff are, or what compromises are made to allow its use in both tranny & primary. I run ATF in my primary, and pretty much have for over 20 years when I had a primary chain. But I like belt drives and no oil even better!

How many miles are your putting on the Syn3?

Even if you run Syn3 MoCo says you still must change it at the same intervals as the standard oil.

I put syn 3 in all holes at the 1000 mile change. The trans has more noise coming out of it. And the intermesh changing gears is not right. I am droping the syn3 and putting in Mobile 75/90.

Good idea, you will never go back to the 20w50 in the trans after you try the gear oil. The redline shockproof heavy works well too. I am using that with excellent results.

did 250 hard miles last Sunday... got home and checked the tranny which HAD Syn3 in it... it was so thin i couldn't see it on the dipstick. the other day i dumped the Syn3 out to put in Mobil 1 75/90 and the Syn3 in the drain pan looked like metal flake paint.

after another hard 250 miles yesterday with Mobil1... Neutral is real easy to find and can feel a distinct firmness when it goes into gear. plus it seemed to eliminate some of the "clanky" sound the tranny had.
