Diesel, all types · per gallon · 1921 Estimated
This figure may be significantly off. It is projected back 73 years from the first recorded price, using general inflation. Items do not track inflation evenly — groceries in particular were far more expensive relative to other goods before modern agriculture, so a figure this old can understate the real price by two-fold or more. Use it for a sense of scale, not as a historical price.

Price history
Record & method
No price was recorded for 1921. This figure is estimated: we took the earliest observed price (March 1994) and moved it back along the category inflation curve — a back-cast of 73 years. The further back it reaches, the less it should be trusted. Treat it as an approximation, not a historical fact.
