Cleaning Differentials with Auto-Rx®
Auto-Rx® is your solution for cleaning differentials, and it works as you drive to liquefy the contamination residue and build-up.
To get the most out of Auto-Rx®, we recommend the following easy, step-by-step method:
STEP 1 Into the differential oil reservoir, add 2 ounces of Auto-Rx® per quart of differential fluid. STEP 2 Drive 1,000 miles and then drain. STEP 3 Refill according to vehicle manufacturer's recommendation. This unit uses heavy gear oil.
The chemical formulation of Auto-Rx® is the same for engines, transmissions, motorcycles, and diesels. The only difference is in the individual applications.
