He did say 70000 Km, not miles. That is only 45k miles or so. With that mileage, I would not be concerned about rear diff fluid, manual trans fluid or coolant.

The problem I have with all of this is fluids have to be changed every 3-5 years regardless of the mileage.

!KLeech!

supposed to be, but you know there are people out there who dont ever do it and never have any problems. then there are guys who do it religiously and still have problems, its a hit and miss kinda thing really.

I have been working on cars for a LONG time and I have never heard that before. If the car only had 70k km on it, the only fluid I would worry about having been changed is the oil.

Proper maintenance (which very few actually do) would be to change engine coolant and brake fluid every 3-5 years with an absolute disregard of mileage.

Coolant does breakdown over time, in fact most manufacturers specify a shelf life (I.e. new ant-freeze sitting on a shelf in its original container) of 5-7 years. Brake fluid is hygroscopic (it absorbs water) and will deteriorate over time even in a "sealed", but vented), system.

For the other fluids, all manufacturer's specify engine oil changes in terms of x miles/x months "whichever comes first". For our Mustangs Ford says 5,000 miles/6 months as the absolute maximum in normal service and 3,000/3 months for special service.

You don't see time specific tranny and differential recommendations as commonly, but if you dig you can find them. Like Average Joe, 3 to 5 years is what I would consider proper maintenance as well...
