I called FCP euro today and placed an order for transfer case fluid, front/rear diff fluid, the trans service kit, 4 replacement drain/fill plugs.
The guy over the phone was very helpful, and gave me a good range of fluids to choose from.
FWIW, one of the ones that works was a "benz" fluid (made by shell) and even the fcp euro fitment guide says that It-Does-Not-Fit-Your-Vehicle but yet the rep says it works. I'm sure that ECS guide is probably in the same boat, and the fluid would still work
