Heat gas grill on medium or charcoal grill until coals are ash white.
Mix together oil and butter, then brush on all sides of corn. Reserve leftover for dressing.
Place buttered corn onto grill. Grill, turning often for 10-12 minutes or until all sides are charred and corn is tender. Use a sharp knife or corn stripper to remove kernels from cob. (Tip: Secure the corn in the center of a Bundt pan, and cut)
Meanwhile, in a medium-size mixing bowl, whisk together any remaining butter and oil, mayo, lime juice, salt, lemon pepper, paprika, cumin and garlic.
Add grilled corn, ¾ cup cheese, jalapeno, onion and cilantro. Mix well.
Serve immediately or chill until serving. Garnish with reserved cheese and cilantro, if desired.
