The white EPDM I'm using has a white material laminated to it...after quite a few oil changes, a brake flush or two, and various other work..there is no damage to it. I can guarantee that at least with motor oil and brake fluid, there is no effect..again, I'm using white material.
I removed the Racedeck in sections to mop it out after a winter of parking..no issues. So the white may in fact be a better bet than the standard black EPDM. Other than the normal vehicle fluids, the only one I have on that list is tolulene..and I'm pretty careful with it as my floor has a drain.
This is the material, sourced from Brock White (commercial supplier) locally:

Btw, the Racedeck Freeflow in my shop is not coddled whatsoever. Floor jacks, wood working tools and tables dragged over etc. It's holding up quite well. The drain aspect of the tiles makes my shop usable for wood work etc, even if there is snow melt on the floor. I do like the product. The only thing I won't do on it is weld...for that I would use a welding blanket. I did try a few tiles from HD..and they were absolute ****.
If you have not top coated your epoxy floor with clear urethane, you might consider doing that and adding sharkbite in the parking areas. My guess is that this would work very well to stop slipping too. This is not a flaw in the product IMHO...it's just something you need to consider if your floor has a smooth surface.
If I was doing a new shop, I'd likely tile it completely with porcelain, but drop the parking area about 1/2" and lay RD free flow tiles (with a floor drain) in the parking area. Snow melt is an issue here, so the dropped floor and drain tiles would ensure you were never stepping in a puddle. A single row porcelain tile "border" around the parking area (properly bonded) with thinset) would lock floating free flow tiles in place..and might look pretty cool too. Just a few ideas for you
Be careful... EPDM is not very friendly with garage floors and oil/fuel etc... It will attack and swell.
