Hi all.
Does anybody have any information if the 2.5 Lt. Diesel motors in the Triton and Challenger are still having clogging problems with fuel since they have reduced the Sulphur content.

Cheers and thanks in advance

Yes The 2010 to 2012 has had problems with the High Sulphur content in the Diesel.

Mentioned about it on this forum, but that was some time ago, just wondering if this problem still occurring, as I have a 2010 Challenger

Head over to and look up "carbon build up" ,a wealth of info there.

I own a 2009 3.2 triton and every second service I get my guy to put a wynns product specially formulated for the sludge issue through the intake manifold. Keeps the carbon build up at bay and I haven't had to resort to new plumbing in of a catch can to keep the sludge from forming.

The 2.5 motor has the same issue.

The product is listed on the forum in the thread i mentioned above. Can't remember the number/name of it now.

Here's the link to the wynns product.

The problem with the surging only makes itself known at about every 25,000kms.
The build up takes time. Interesting that a mate of mine has a 3.2 Pajero with the non-common-rail motor and he had this stuff put through his intake system and fuel tank and couldn't believe how much better the thing went when it could breathe better.

My Mitsi dealer uses this stuff,(although I use my own mechanic) and the dealer said they have made it a common thing to do every second service of a diesel motor.

Thanks Landed eagle

I have just reached 22000Km, so I will take your advice on board and make sure the Mitsu dealer is using this product, otherwise I will put it in myself.

Thanks again.

I should add that the issue is different for all vehicles. Some of the other forums memeners get to 60,000 and claim to have no problems. Mine is around the 25,000 ,yours may be different again. must depend on the driving style I suppose.
