What is compression per cylinder for jeep wrangler 2.5l?

The compression ratio for a Jeep Wrangler 2.5L engine is typically 9.0:1 to 9.5:1. This is a *ratio*, not a measurement of pressure in PSI. You can't find the compression *per cylinder* in a simple ratio like this; it's the relationship between the total volume of the cylinder at the bottom of the stroke and the volume at the top of the compression stroke.

To get the actual compression *pressure* in PSI, you need a compression tester. A healthy 2.5L Jeep Wrangler engine will usually show between 150 and 180 PSI per cylinder, though acceptable ranges can vary slightly depending on the specific year and model. Even within that range, slight variations between cylinders are normal, but significant differences indicate problems.
