I wasn't much of a mechanic before I purchased my VX about 7 years ago, but thanks to a willingness to experiment and this forum, I can say that nearly all of the work that has ever been done on my VX was (ultimately) done correctly and completely by myself. My timing belt turned out to be the most difficult job I've done, but only because there was incorrect information in the shop manual. Others fortunately have the benefit of learning from my mistakes, as I documented everything here. Nearly every problem you will ever run into can be solved here with some patience and perseverence. So if you are considering learning to work on your VX, I can say that my experience with this forum has made all the difference in the world.
Learning to do basic maintenance like changing your oil requires very minimal tools and will save you some money, but more importantly it will save you from a great deal of frustration dealing with the Jiffy Lube monkies. You'll know that your vehicle is being serviced properly and you'll gain the confidence to do increasingly complex mechanical work. In my opinion, the VX is actually fairly easy to work on, and sometimes it's even fun!
I recently put a down payment on a new vehicle (an 06 VW Jetta TDI) and I fully intend to do all my own work on that vehicle now also. I've found an enthusiast's forum similar to this one where I'm sure I will find solutions to any common problem I may run into (and probably the uncommon ones too).
The diesel community seems to be fond of oil extractors, which allow you to pump the oil out of the motor (usually through the dipstick hole or oil fill hole). Many claim that they get a lot more oil out that way. The process is very simple. One company that sells these is Pela. I think the Pela 6000 is about $60.
The only issue I have with the Fumoto valve is that since it protrudes from the oil pan a lot more than the OEM drain plug, there is more potential for it to be damaged. If you regularly take your VX offroad I personally would NOT recommend this valve, as knocking a hole in your oil pan leaving all your oil on a boulder somewhere would not be a pretty sight. On the other hand, if you never leave the hardball these things are great and the Fumoto appears to be much better made than any that I've seen at the auto parts stores.
