*Net Profit Calculation: Profit calculations are based on service price minus operating costs. Operating costs include: differential gear oil ($25 per service for 2-3 quarts), labor (30 minutes @ $200/hr = $100), and overhead (30% of service price). At $200/service, total operating costs are $185 ($25 fluid + $100 labor + $60 overhead), yielding $15 net profit per service.
I've been using Engine Clean since 2014 and they still offer the best brake and differential machines on the market. I've worked with numerous other companies over the years and Engine Clean has stood out above the competition.

FAQs
Can the Rx-DF1 handle differential, manual transmission, and transfer case service?
Yes! The RX-DF1 is a multi-fluid capable machine designed to service differentials, manual transmissions, and transfer cases all with one unit. The flexible new fluid rack holds either one 128 oz container or two 64 oz containers, giving you the versatility to switch between different gear oil types and viscosities.
What types of gear oil can the RX-DF1 handle?
The RX-DF1 handles all common gear oil types including conventional and synthetic formulations. Whether you're working with 75W-90, 80W-90, 75W-140, or manufacturer-specific fluids, the RX-DF1's fuel and oil rated hoses (rated up to 150 PSI) can handle them all.
Why choose shop air-powered over electric differential machines?
Air-powered machines eliminate electrical failures which is the #1 cause of equipment breakdown. No motors, batteries, or solenoids to fail means higher uptime, lower maintenance costs, and longer equipment lifespan. Simply connect to your shop air (80-110 PSI) and you're ready to work.
How long does a differential service take with the RX-DF1?
The RX-DF1 streamlines what used to be a messy, time-consuming job. With our industry-leading 2.5gpm pumps and intuitive control panels, you can complete a full differential fluid exchange quickly and cleanly, maximizing your shop's productivity.
What's included with the RX-DF1?
The RX-DF1 includes dual 2.5gpm pumps, aerospace-grade hardware, fuel and oil rated service hoses (150 PSI rated), intuitive control panels, easy-to-read gauges, and a flexible new fluid rack that holds one 128 oz or two 64 oz containers. Accessories sold separately.
How does the RX-DF1 compare to 3-System Machines?
Unlike bulky multi-system machines, the RX-DF1 is purpose-built for differential, manual transmission, and transfer case service. At just 70 lbs, it's lightweight and easy to maneuver. The simplified design means fewer parts to fail and easier repairs when needed.
