My 4.8 sits for weeks at a time before I'll drive it once for 20 miles or so. Then every few months I'll take it to Houston and add 500 miles to it. She's coming up on 130000 soon. I'll post a pic when it gets there.

There's a grip of maintenance (long list) that I have queued up for it, but it's been behaving so nicely that other projects keep taking precedence.

an X5 needs to be driven to become reliable?

Both summer & winter gasoline formulas in my N.Texas area (DFW Metroplex) are similarly reformulated, so no conventional gasoline is available; I've never noticed much difference season-to-season.

During the 3.5 years that my neighbor was rebuilding/restoring the X5 (in order to trade it to me for my '66 Chevelle), he started in the engine compartment. I know he replaced all the cooling components (excepting the mechanical fan), then the plugs, coils, injectors (using good quality replacement parts, though not the "best"...like Bremi coils, Bosch plugs, etc.), and finally, (at my insistence, just prior to the swap date, replaced the timing chain & guides). He spent a lot of time on the suspension, and it drives perfectly, better than any "new" car I've owned before; considering it has over 210k miles, it drives phenomenally well.

Peripheral equipment was done as-needed, with added aftermarket towing added, a cheap non-Android radio, and adequate Yokohama YK-HTX tires (nothing special, I'll upgrade later), so I've been adding-to and doing my mods around the edges. I've just started to add my StaBil fuel stabilizer to the X5, and will again, if I ever fill the tank for a third time. Lucas injector cleaner, maybe, too.

My EE neighbor never had codes that set SES lights, or he would've fixed them, as a conscientious engineer would (he drove it about 5k miles during the 3.5 years while fixing it), so I figure that my bad luck recently is the direct result of not driving it enough. I've other vehicles that have seemed to start degrading only after sitting awhile. My codes only started after it had been mostly sitting for five months. I expect some items to fail, as a matter of course, but just trying to understand the inter-linked web of BMW codes, modules, sensors is new to me. So I'm slow on the uptake, it seems. Not the mechanic I used to be.

I still had the original injectors in my '02 at 389,000 miles and never used any fuel treatments, just ran Shell premium gasoline. I think too much of that Seaform and you'll be replacing converters too soon.

266,000 miles on my '06. Still running original injectors. Mileage seems to be getting worse. I do a lot of short trips and around town driving, so I expect that, but it used to do better on the freeway than it has been lately.
