Review: Questo olio per differenziale è veramente fantastico e mantiene ciò che promette. E' bene ricordare che è un olio per differenziale e non va usato nei cambi con sincronizzatori. Leggere le indicazioni di utilizzo e la scheda tecnica, sono chiare e ben fatte.

**Q: What is the viscosity of this? Need a specific number.**
A: Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90. This is from the manufacturer's site.

**Q: Canged primary chain OIL of my 2002 RoadKing ScreamingEagle I made a MISTAKE! Added REDLINTransFluidw/Shockproof. IS It COMPATABLE**
A: I would think not.  As the primary runs a 20w 50 and the red line is something like 75 90 it's going to a lot thicker.  I would call a local Indy not HD and ask them for sure.

**Q: Is this GL5?**
A: It exceeds API GL-5 specifications.

### ⭐⭐⭐⭐⭐ Review
*by T***Y on 1 November 2016*

Used this in my 1999 Subaru Impreza Outback Sport with noisy front and rear differentials. I threw some mobil0-1 75w-90 in each diff for about 1k miles to rinse things out. Just dropping the beat-up, dark diff fluid and going to Mobil 1 was a marked improvement alone. After running that sacrificial fluid for 1k miles, I drained it (and it was in much better shape, but still appeared QUITE DIRTY) and installed some Lucas full synthetic 75w-90 gear oil with about a half of the Heavy Shockproof quart going into the front and a half going into the rear diff. I put the Redline in first so it would mix better. Both my front and rear differentials are OPEN (not LSD; if you have an LSD, DO NOT USE this redline shockproof series). Immediately, I noticed that the diffs were notably quieter and that the car even accelerated and coasted more easily than even with the mobil-1 gear oil. I used the heavy shockproof because I'm in Florida and it never gets very cold here (it dips below freezing for a few hours, a few nights of the year, but only just below). If you are not in a southern state (FL, Texas, AZ, NM, LA, etc), I would advise selecting the lightweight shockproof instead. Overall, I'm extremely satisfied. If you have an open diff, or an air locker (anything but an LSD), you owe it to yourself to add a portion of shockproof to your diff. Quieter means cooler. That's always a good thing. Also, NEVER add this to any transmission. Even a manual. Your synchros will be permanently too slippery to work properly.
