What is the shelf life of xdp

I have used OptiLube in my 2003 Dodge Ram Cummins for nearly 200,000 mies and in my used RV Caterpillar inline 6 for over 60,000 with no apparent loss of behavior in either rig. I buy it by the gallon and recently used some summer formula that is at or near a yea old. The cummins was giving me injector troubles at 40,000 miles when Opti Lube was recommended . The motor smoothed out with the first bottle and is stillrunning of the factory injectors with no issues. The old Cat engine smoothed out with the first use and runs smooth as silk, If there is a "shelf life" problem I have not experienced it. USE IT religiously if you want a quieter, smoother engine! .

Does the XDP line have cetane boost?

Yes, ZPD is about 3 points on the Cetane increase per dose.
