Rotrex SX150 Traction Fluid - 1 Liter (R50-S150-OIL)
If you're running a Rotrex supercharger, this is the fluid that keeps it alive, and there's no substitute for it. Here's the thing that makes a Rotrex different from every other blower out there: it doesn't use gears to move power, it uses traction drive, which means power gets transferred through a thin film of this exact fluid between the spinning components. That's not a detail you can fudge. The fluid isn't just lubrication, it's literally how the supercharger transmits power, so running the wrong stuff or letting it go too long is how you cook an expensive unit. Grab a bottle for your scheduled change, or keep one on the shelf so you're never caught short when it's time.
This Is The Fluid, Not Just A Fluid
Don't think of this like the oil you'd top off an engine or transmission with. The SX150 is built specifically for the traction drive inside your Rotrex, and it has to do something most fluids never do: grip hard enough to transfer power while still flowing like a lubricant. It's engineered to hold that grip through the heat and the load of a supercharger spinning at tens of thousands of RPM without breaking down. Pour in regular oil or some generic transmission fluid and you're not saving money, you're slowly destroying a unit that costs a whole lot more than a bottle of the right fluid. There's a reason Rotrex only signs off on their own stuff.
Change It Every 50,000 Miles (Sooner If You're Pushing It)
Rotrex wants this swapped every 50,000 miles, and that's the number for a street car living a normal life. If you're making big power or you're hard on the car at the track, do it more often, because the fluid wears out faster the harder you work it. And worn-out fluid isn't a small deal here. As it breaks down, it loses its ability to transfer power cleanly, your supercharger starts running hotter, and that heat wears it out quicker, which is the exact opposite of why you bought a Rotrex. This is one maintenance item you really don't want to stretch.
Keep One On The Shelf
One liter is what a fluid change takes, so a single bottle does the job. That said, it's smart to keep a spare around. When your Rotrex is due, you want to knock it out that weekend, not sit around waiting on a shipment while your supercharger runs on fluid that's past its prime. A backup bottle in the garage means you're ready whenever the mileage comes up.
