My Car Manager

Must start added vehicles at 0 miles. If several thousand miles are on the car the mileage calculations will be off, unless you want to manually calculate miles driven on each tank.

Right click and choose add at the bottom panel to add things. Sometimes "add" will open another menu to choose an item. A photo of your vehicle must be 200k or less according to the info, but I had no problems yet. Needs an import feature for those moving from apple/android systems as I am NOT going to enter 3 years of data for 3 autos. This is a good program if you are willing to manually add the entries or are just starting a log. Needs to save data to skydrive for sharing between devices.

It doesn't explain what goes in the fill in spots. (i.e. sum, vol.) They need to have a help function to explain some of this as it's not self explanatory. It would be a better and easier program to use then. I'm still using the program but because of my above examples I'm still not certain of my actual costs.
