The compression ratio for a 2001 Ford Ranger with a manual transmission varies slightly depending on the engine. Ford offered several engine options that year. You'll need to
specify the engine size (e.g., 2.3L, 2.5L, 3.0L, or 4.0L) to get an accurate answer.
The compression ratio isn't typically listed on readily available specifications, and will be in the owner's manual or a service manual for that specific engine.
