Recently we have begun a search for a new tow vehicle. We currently have a 2005 Dodge Durango with 325,000 miles. We found a 2014 Dodge Durango and had it taken in for a complete inspection. I asked for a compression check as well.
The compression check came back with the following:
1 -2-3-4 140
5-6 150
7-8 190
Does this present an issue with towing? What would it take to return six cylinders to 190? I'm not a mechanic but don't want to buy trouble either. It's a nice vehicle and has the 5.7 Hemi which we have on the 2005 and it tows beautifully.
Thanks in advance.

would need to do a wet/dry compression test, where you would squirt some oil into the low cylinder and perform the test again. If the compression comes back up, it is usually and indication that the rings are not sealing.

What happens when towing with the compression numbers I listed?

its not a question of towing, its even driving, as a rule you shouldnt have a cylinder compression differential more than 10% of the manufactures posted compression. so there is a good chance what this is telling you is the motor needs a rebuild.
