I was thinking... what if one just put parallel plates under oil and used the oil as a dielectric? Do you think this could work? Since the oil is completely touching the plates, capacitance wouldn't be dependent on pressure, and it could be the most reliable homemade cap ever if done correctly. Vegetable oil has a dielectric strength of about 47MV a meter, so the plates wouldn't need to be too far apart.
Now the best part, if the dielectric breaks down, just cycle the power and it's good as new! This could possibly start a whole new era on tesla coil capacitors. :p

Every time is arced, it would create some compounds which would build pressure in your container. It slowly would drop in flash over and would need to be filtered. Heres a test cup with adjustable plates used to test oil.

The oil won't provide structural support, so there may be some flexing from the electrostatic attraction. If the plates are very close together you'll need to make sure this doesn't cause arcing.
If the plates are stacked the inner plates should not feel a net force since they will have oppositely charged plates on either side, but there will be two plates on the outside which feel a net force, so perhaps these two can just be made thicker.
