Oil-the-chemical and oil-the-fuel can be considered seperate products. Demand-wise, all uses besides fuel are trivial. Even plastic is only 4%. The spritz of 10W-40 on my bike chain is of 0 consequence compared to the gallon of gas burned in a typical daily commute by car. We're never going to run out of oil for all those important non-fuel uses. Even if every oil well ran dry tomorrow, oil-the-chemical is quite easy to make from carbon waste feedstock. I don't think it's right to estimate such a long time for oil to become obsolete as a fuel, just because we use it for other things too.
