Hi all, I am looking at the Severe Usage Conditions maintenance schedule, and am seeing two different, but similar mentions of salt usage on roads. Can anyone tell me what the difference is between C - Driving on a salt-spread road, and D - Driving in areas using salt or other corrosive materials? I drive in Toronto, so yes, salt is used, but which is that classified under? Both C and D have different schedules. Would a salt-spread road be like if I were driving near salt-flats? Trying to figure out if I will need to change the reduction gear fluid every 120,000kms (still a long way away, but I would like to know).
