Hi.
First time trying to do the fluid changes "privately" so a little confused and would appreciate some pointers.
Profile of car, weather, and driving patterns:
Canada. 4Matic 2012 S550. Car has 145K KM (90K Miles). Weather averages around 30C (86F) in summers and around -25C (-16F) in winters. City (stop & go) driving. No engine oil leaks or oil burning issues.
Engine Oil:
Google search suggests any of these as suitable: 0W-30, 0W-40 (All TEMPS) 5W-30, 5W-40 (Above -25). Which would be best?
They had put 5W-40 the past few oil changes. Don't know why. Is that the most suitable type? Or, should I use a thinner grade (0W-30 or 0W-40)? What are the pros and cons of each? I have heard that thinner oils (0W-30 or 0W-40) would be easier in winter but are prone to cause leaks. ???
Transfer Case:
I have been advised that it is linked to Transmission. If so, then the same fluid as Transmission will take care of the Transfer Case too, right? If not, what is the fluid spec for this?
Rear Differential:
Which fluid to use for this?
I am of the understanding that all four of the above fluids need to be changed. If something needs to be added to or subtracted from this list, kindly advise.
First of all it's unlikely you can change transmission fluid yourself. Fluid is both added and drained from the same hole in the pan. Special tools are required. Pan bolts are one time use only aluminum. You wont find correct fluid at a flaps
