★ Top Answer
The Ford Mustang's 8.8 rear end needs around 2 to 2.5 quarts of gear oil for the differential. The recommended viscosity is 75W-90 synthetic gear lube. While various brands are available, users suggest that Lucas Oil or Mobil 1 offer the best quality lubricants. Prices for gear oil range from $7 to $15, depending on the brand and additives included. It's important to replace the fluid in the differential every 30,000 to 60,000 miles and more frequently if you frequently drive in rough terrains.
