Unique to the industry, BG Products works, as it always has, through a close-knit network of independent distributors.
Through extensive testing, OPMustang.com found that BG Syncro Shift II Synthetic Gear Oil is one of the few products that have been proven to work very well in the troublesome MT-82. While Automatic Transmission Fluids (ATF) are often recommended in manual transmissions for their light viscosities, they suffer from low film strength, induce severe fluid shearing, and greatly sacrifice wear protection.
BG Syncro Shift II is a gear oil that is specially formulated for manual transmissions, transaxles, and transfer cases and provides outstanding extreme pressure characteristics, film strength, shear stability, wear protection, and seal compatibility without sacrificing low temperature fluidity or performance characteristics. It may be used in all domestic and import vehicles where engine oil, ATF or GL-4 gear oil is specified for manual transmissions and is suitable for:
-FORD XT-11-QDC Spec.
-WSS-M2C200-D2,
-GM PN 12345349 (specification 9985648)
-FORD PN D80Z19C547A,
-PN ESRY19C547A
-MERCEDES-BENZ PN 900260315
While viscosity ratings, indexes, flashpoints, and other metrics don’t tell you anything about the quality of the base oil stock, additive packages, lubricity, etc… let’s look at how BG Syncro Shift II stacks up against some common transmission fluids:
| BG Syncro Shift II
cSt @ 40*C – 37.85 cSt @100*C – 7.11 Flash Point – 212*C (413*F) Pour Point -43*C (-45*F) Viscosity Index – 153 SAE Viscosity Grade (Motor Oil) – 5W30 SAE Viscosity Grade (Gear Oil) – 75W80 |
RP Synchromax
cSt @ 40*C – 38 cSt @100*C – 7.7 Flash Point –420*F Pour Point -66*F Viscosity Index – 175 SAE Viscosity Grade (Motor Oil) – N/A SAE Viscosity Grade (Gear Oil) – N/A |
| Redline D4 ATF
cSt @ 40*C – 34 cSt @100*C – 7.5 Flash Point – N/A Pour Point -60*C (-76*F) Viscosity Index – 198 SAE Viscosity Grade (Motor Oil) 0W20 SAE Viscosity Grade (Gear Oil) 70W80 |
Redline MTL
cSt @ 40*C – 54.1 cSt @100*C – 10.4 Flash Point – N/A Pour Point -50*C (-58*F) Viscosity Index – 185 SAE Viscosity Grade (Motor Oil) – 5W30 SAE Viscosity Grade (Gear Oil) – 75W80 |
Lower Viscosity Index = Greater the change of viscosity of the oil with temperature.
Here we see at 40*C (104*F), BG Syncro Shift II is actually thinner than Royal Purple Synchromax and Redline MTL, however it is a bit thicker than Redline’s D4 ATF. At 100*C (212*F), a typical operating temperature, BG Syncro Shift II is the thinnest of the bunch with a similar flash point to Synchromax, but the highest pour point of -45*F (the temperature where a liquid becomes a semi-solid and loses its flow characteristics.

How often do you recommend the transmission fluid be changed
It’s hard to generalize and really depends mostly on the use of the car. For the street (and even occasionally tracked car), it’s typical to change manual transmission fluid every 30K miles, but most go much longer than that (I’ve seen some cars go 60-100K) with no issue. The more you track your car and the hotter the transmission runs, the sooner you should change your trans fluid. Unless it’s a dedicated track car, even with a good amount of weekends, every 15K is probably more than enough.
Did you use the 6 oz. Bottle of BG gear supplement also ?
I’ve have seen comments that the Redline DCTF is as good or better than the BG Syncro shift 2. Any opinion on that fluid and is it suitable for the mt-82?
I read reviews on some Mustang forums stating that the BG Syncro Shift II may be a little too thick at 75W, even though it matches the FORD XT-11-QDC Spec . Is this a problem? I own a 19 Ecoboost Premium PP 6 SP MT and was considering replacing the factory fluid.
