Also, make sure the last run before parking it up gets it properly hot to ensure engine and exhaust are fully dry.

I have an xDrive 7 series as my people carrier, so if I want safety and comfort - I can use that one in the winter, but the Z4 is definitely more fun to drive (as always). And that's exactly what I bought it for. Especially in fresh snow, with the top down - it's priceless.Christopher72 wrote: ↑Fri Sep 22, 2023 7:40 pmThat's cool - That's how I learned the difference between summer and all-season tires - the hard way ... several of my E46 convertibles I ran all year and they were ragtops. For some of us, these are seasonal cars, not because of any limitation of the E89, just because we have other cars. I use an AWD SUV to deal with Ohio late fall and early winter.... or rainy days... or big flocks of birds....
I don't know about filling the tank; petrol will degrade quite a lot in the months the car is stored (assuming it's at least 3 months). I'd keep the fuel level low and refill it (from a canister, for example) with fresh one before starting it in the spring.
Never thought of condensation... At any rate, if someone is storing for a year you can add some petrol stabilizer, correctly dosed. We only have about 4+ months of too cold for topless.ronk wrote: ↑Sat Sep 23, 2023 12:53 pm The tank should be filled to minimise air space in the tank and thus surface area for condensation to form on the tank wall.
The fuel does not degrade enough to notice - I store mine for five months sometimes six using this regime and never had the hint of a hiccup when I start using the car in the springtime.
Yes, I've seen this phrase (it usually says "6 months to one year without significant degradation" though). But if you read the next one, you'll see that "However, fuel that is exposed to oxygen, moisture, or contaminants can deteriorate more quickly, resulting in reduced quality, lower octane rating, and increased levels of sediments or sludge." Meaning as soon as it comes out of the pump, it enters in contact with oxygen and moisture and starts degrading. Filling the tank doesn't count as resealing the container.
<Sigh> I honestly think the internet will be the end of civilisation.
