Sealing Oil Pan Red Permatex Vs. Ultra Grey Options

[rave2n]

Just curious for some insight before I seal these oil pans this evening.

I've purchased high temp red permatex for the oil pans, but I've been reading around to use the Ultra Grey. No one seems to give a good reason behind such, so I figured I'd inquire with you folks.

Lets here some reasoning!

Please don't say use Toyota FIPG or whatever it is.

Gray is for high torque applications, red is for high temp, black is for maximum oil resistance, and blue is "sensor safe" I believe. Always buy black or gray, you cant go wrong with either.

Scrub scrub scrub and get every molecule of oil of the gasket mating surfaces. Apply a thin film of RTV/FIPG to the pan and spread it evenly with your finger. Attach the pan and lightly torque it. Let it sit for 12-24 hours then torque the bolts the rest of the way down to specification.

I used black RTV on mine, 6000 miles later no leaks.
