200k miles?

Some questions about the durability of Gen 4 SHOs

1) what is the highest mileage gen. 4 sho that you know of?

2) I hope this is not sacrilege but my goal is not to increase hp - my goal is to get my sho to last as long as possible with the fewest number of repairs. I have a 2015 pp sho.
A) is using drive rather than sport mode better for the transmission?
B) from a longevity stand point is there any difference between 87 and 93?
C) other than changing my oil every 5k miles with premium synthetic, is there other preventative maintenance that should be done?

Ricflair, not to disparage your goals in the slightest but I am curious why you would own an SHO if longevity with fewest repairs is the primary goal. A nice Taurus Limited with the naturally aspirated 3.5 would likely be a better candidate for maximum longevity simply because there are no turbos and associated hardware to worry about.

If you do not care about or use all the power, there is likely no longevity difference between running 87 and 93. Of course, you will not be getting all the power or mileage that the SHO is capable of. Sport mode locks out 6th gear unless you manually select it so Drive would probably be the better choice for longevity.

All of the regular routine maintenance should be performed along with PTU and RDU changes every 25,000 miles. I would also have the transmission fluid changed at the same time.

^x2. I would also recommend severe service intervals for longevity. Should be in the owners manual.
