Planning a 11 hrs Trip on a CLK500?
It does have a brand new drive belt, engine oil/filter, transmission oil, air filter, differential oil( less than 3 months or <500 miles ago).
Question is, do I need to do anything special to prepare the car for the trip? Any other tips or suggestions would be greatly appreciated.

P.S:Michlein tires have less than 8k miles on them too.





I have an 08 550...... 113K
Took a 1400 mile round trip in it last month. I've done this a few times. It's wasn't much different than sitting on the sofa and watching movies for 11 hours...

Check not only your spare, but inflate your tires to 2 pounds over recommended. This will reduce the heat due to the prolonged flexing of the tires and keep their performance closer to norm.
Check fluid levels, lights, etc.
I carry a bottle of detailers spray, cleaner wax spray, a small sprayer bottle of water with a drop of dishwashing detergent added and 2-3 small microfiber towels. I use the wax and detailers spray for the return trip. I use the water sprayer if my windshields need cleaning when I refuel and/or the headlights (bug splatter).
Have fun and be safe......
Are you talking about two pounds over the desired non-warm ones? Since, warm tires are already recommended to be "Recommended+4"
I'll make sure to check all other fluids too. Maybe keep a quart of engine oil too, in case? Or no?
Thank you




The tire pressure was +2 over the cold recommended value, which is what is on the stickers.

Usually cracks in the rubber means time for replacement. Never knew about the fluid, thanks for that tip. I'll put the car on ramps and will inspect it thoroughly.
I tried to take brakes after 2-3 hrs, just to make sure car is getting enough rest and it was all good.

Thanks again everyone for all of your advice
