1984 Chevrolet K20 Pickup 4WD — 6.2L 8-cyl, 4-spd manual, AWD
This 1984 Chevrolet K20 Pickup 4WD (6.2L 8-cyl, 4-spd manual, AWD) runs on diesel. DIESEL
At today's AAA national average price ($4.78/gal, 2026-07-05) — the EPA's own price/date assumption isn't exposed in the public dataset, so we recompute this from the EPA's MPG figure and a sourced current price.
This 1984 model was originally EPA-tested under the pre-2008 2-cycle method, which didn't account for highway speeds over 60 mph, air-conditioner use, or cold starts. When EPA overhauled the test for model year 2008, city ratings fell by about 12% and highway by about 8% on average industry-wide — and EPA retroactively adjusted every 1984-2007 rating to the stricter standard so old and new cars could be compared fairly. The MPG above is already on that modern scale — the window sticker on this car when it was new likely showed a higher, pre-2008-method number.
