I live in Southwest Florida and was wondering what the best oil is for my 2010 V70 R Design. It currently has about 201,000 miles on it. Historically been using Amsoil 0W20. Should I use semi or fully synthetic oil ?

As an aside, does anyone see many 2008-2010 R Designs?

How do I replace the coolant overflow hose in my 2010 V70?

I noticed that the tube that runs to the top left side of the coolant reservoir is kinked. I purchased a new hose, but I can't see how to remove the old one. Any suggestions? Also, how to install the new hose?

I have a 2010 V70R with the parking brake not releasing. This has happened twice in the last few weeks, both times when I start the car, release the electronic brake, it backs up slowly. After I move forward I feel like the rear is dragging then a chattering sound and smell of burning rubber. I stop...
