I used the EIA spreadsheet for oil prices and calculated the rolling 20, 100 and 200 day price increases (and decreases, if applicable) since 1983, then sorted for size to get the following:

Most of the big historical price spikes occurred during the Gulf War.
Note that the last mini-recession, (2000) and the real recession (1991) were preceded by substantial oil price increases.
Also note that the oil price pretty close to doubled in the year before October 1987. This price rise was slow enough not to really rank very high on the "spike" lists, but was more of a slow-motion increase. If energetic, you might be able to graph this for us. The diligent pumping of money into the economy by Bubblespan saved us from an outright recession or worse. The so-called dot-com bubble burst of late 2000 early -2001 was also preceded by rapidly increasing oil prices in 1999.
In the grand scheme of things, on a percentage basis (which kicks out inflation) the current price rise we are having is a lightweight compared to some of these instances in the past. But, another 20% or so ($11 per barrel) might be enough to change the picture if done fast enough.
