Xciting 500 / Re: How Crucial is xciting 500 4k Service timing?
« on: September 08, 2017, 03:01:26 AM »As a retired engineer, I can tell you that the factory service intervals for most equipment are set rather conservatively in order to protect against worst-case problems. You can generally get away with extending those intervals with no ill effects (and here's the catch) but not always. So if you go beyond the recommended service intervals, you are betting that you will be lucky. As a general rule, we allowed 10 percent variance automatically (so a 4000 mile check was fine up to 4400 miles), and in extenuating circumstances, 20 percent was viewed as acceptable (up to 4800 miles). A lot also depends on how you're using it. The factory intervals are for normal treatment. Harder usage would suggest shortened intervals. So as the saying goes, "Your mileage may vary."
What constitutes harder usage? I heard have this before but am at a loss as to the meaning.
