## Description

LUBRICANT

Review: THIS is the modifier you need and want to use if you have a 2004-2006 GTO w/the M80 rear diff... - GM stopped making and stocking everything for this car. It's extinct. Parts are sparse. But gratefully this little bottle of magic still exists, and is affordable! Change your rear diff fluid every 18-24 months or every 15-25k miles if you own an 04-06 GTO. The LSDs are a metal on metal "cone type" design, so the amount and quality of FM you use is critical, as is flushing the fluid frequently to excrete metal slush in the diff housing. A quality 75W-140 gear oil works very well. Start with 2oz of the modifier, then ~1.5-1.8qts of the gear oil. Drive the car around for a while and listen to how the rear end sounds when turning and performing slow-speed maneuvers in parking lots. Add 0.5-1oz at a time to tune the diff. Let me know if you found this review helpful. 👌 🍺 ✌️

## Questions & Answers

**Q: Should I flush my engine oil before switching from conventional to synthetic oil or vice versa?**
A: No, it is not necessary to flush your engine when switching between motor oils. Typically, conducting a routine oil change and replacing the conventional oil with a synthetic motor oil will not require any additional maintenance.

**Q: Do I need a special oil filter for a synthetic oil?**
A: No, synthetic motor oil does not require you use a special filter. Oil filters are used based on vehicle specifications. Refer to your vehicle Owner’s Manual for guidance on what type of oil filter to use.

**Q: Is there a way to tell if my engine oil needs to be changed or is running low?**
A: Yes, if equipped, your vehicle’s oil life monitoring system will inform you when your motor oil needs to be changed. Refer to your vehicle Owner’s Manual for more specific guidelines.

**Q: Does my transmission fluid need to be changed as regularly as my oil?**
A: No, typically, transmission fluid lasts much longer than most engine oils. Refer to your vehicle Owner’s Manual to identify how often and when your transmission fluid should be changed. Severe usage and regular usage descriptions are provided.

**Q: Is there a difference between power steering fluid and transmission fluid?**
A: Yes, there is a difference. There are many types of transmission fluid. GM Genuine Parts and ACDelco recommend referring to your vehicle Owner’s Manual for fluid recommendations for all vehicle systems.

### ⭐⭐⭐⭐⭐ It is a must for 2021-2025 Yukon's and Tahoe's in rear driveline oil!
*by T***M on March 5, 2026*

Put this in my 2021 GMC Yukon Denali rear driveline oil when I changed it out and it took away the low moaning noise we had while turning! It is a must for 2021-2025 Yukon's and Tahoe's in rear driveline oil.
