How hot is a normal temp for a differential with 3:36 gear ratio? I have a 67 Impala and it feels quite hot, but no noise. What would be the very best gear oil and would a differential cover with fins help?
All dead dino based oils start to oxidize at 230 to 260 degrees Farenhieght, but the ignition point is a lot higher. For those that read SciFi you know that paper catches fire at Farenhieght 451 according to Ray Bradbury's research. Oil will be close to that ignition point as well.
