It doesn't matter what grease you use. If it got hot enough to melt the grease, it would also be hot enough to melt the seal and bake the grease inside the bearing into black crust. And the bearings would fail.
The Mobil 1 grease is excellent and can be used for everything. My preference would be Bel-Ray waterproof grease for the added waterproof factor, but use up what you have, first. All standard greases are good to that 350° range, and at that temperature the bearings will lose their tempering and fail. If a bearing is hot enough to take the skin off your finger, even below 350°, you have a big problem, anyway.
"Older people who are reasonable, good-tempered, and gracious will bear aging well. Those who are mean-spirited and irritable will be unhappy at every period of their lives.
"Let each of use properly whatever strengths he has and strive to use them well. If he does this, he will never find himself lacking."
Marcus Tullius Cicero
