My 94 with a 2.5 is at 283,865 and runs great. Make sure you get your systems flushed and keep it tuned up and it will reward you by going strong

It will likely last until you have a series of other unfortunate financial setbacks that have nothing whatsoever to do with Jeeps.

the 2.5 can really last forever... it depends on how well you care for it.

The 2.5 can last every bit as long as the 4.0 with good maintenance. I think most are killed by overheating. Always trust the gauge unless you have MEASURED it being wrong. As soon as it starts running hotter than normal, pull over and figure out what is wrong. Once the needle goes past its normal point its going to keep climbing till your head gasket goes pop and other fun stuff starts to go.

In saying what everyone else said, doing maintenance and keeping a conscious eye on issues as they come up with keep any engine running a long time. The 2.5 is a tank but even it can be killed if not maintained.

In theory, any engine with a parts source is immortal. It's your checkbook that has the finite number attached to it and your tollerance for pain that sets the time line.

125k on Edith, (my 2.5 95 YJ) Runs perfect. YJ series motors are anchient, time tested engineering. X2 on fluids and maintenance and above all else, know the diffrence between driving hard and abuse.

not a jeep but

I know it isn't a JEEP but the Jeep I6 and I4 along with the vernable Buick 3.8L are certainly every bit as good and durable as the Saab. A Wisconsin salesman donated his Saab to the museum with over 1,000,000 miles on it. It had the transmission replaced ata bout 200,000 miles but the engine had no major repairs,

I know a cab company in Minneapolis concentrated on Ford ex police cruisers and they would routinely get over 500,000 on the Ford engines.

The thing that Jeep Wrangler's have against them is that they are not typically used for long, continuous interstate driving. short, off road driving is hard on longevity.

Again, regular maintenance and no extreme encounters, such as major overheating.

Mine had a new engine at 112,000. From what I have seen 200,00 is luck on a 2.5. while 300,00 + is not uncommon on a 4.0. I have had 3 with over 300,000 and ran great, but this is my 1st 2.5 (90 YJ) and I am not impressed at all

Purchased my 94 in Sept '11 with 114,000. Now it just turned 123. My Bayliner (boat) has the same engine (boat is carburated and Jeep is fuel injected) and it runs awesome! Boat has 100 hours on it but if I use it as replacement itl would be like new! 2.5 has been around for very long time for a good reason.

i owned a 91 2.5 that i sold with 405,045 miles on it, it didnt burn a drop of oil and ran like a champ.

they are gutless wonders, but they are SUPER durable. keep oil and water in them and they will run forever
