My Roxor is tough and does well in El Paso. It's my daily driver. I do crawl and off-road often. But the extreme heat is hard on turbos, diffs, and what not. I already run some I'm my engine. I use Rotella T-6 for oil and she seems to love it. I'm thinking about adding Lucas to the diffs and transfer case for added protection. Would yall be willing to share your opinions? It would be much appreciated! Thank you very much in advanced.
