Hi ya'll! I'm totally new to diesel but have learned some good information from forums like these so decided to sign up. Hope ya'll don't mind but I have a few questions (may sound stupid)

Question: I live in San Antonio, Tx area so based on TXLED can I rest at ease that the minimum cetane rating is 48 or should I still run motorcraft cetane booster? I have not for the past year. 2014 F250 140,000K. Based on what I've heard the CP4 is know to fail from lack of lubrication so was just curious. I do not do any towing besides a very light Jon boat 3 times a month.

On a side note and different subject....had someone help me with a fuel filter change a few thousand miles ago (I replace both every 7500 miles) and they failed to get the frame mounted one secured to a stop. Next thing I know I got the low fuel pressure warning and reduced engine power warning. Was then told it was OK to drive home like this (12 miles). Seems like a good way to damage or destroy the CP4 no? Or does limp mode somewhat temporarily protect it?

Hi and welcome!
It is definitely worth your while to use an additive for the fuel. You will get 1001 opinions on what is best but stick to a good name brand and try a couple out. See what suits your driving style and climate. More is not better so adding "extra" to the tank is wasting money.
Can't help ya on the fuel pressure issue. I would think that if it was leaking out of the filter housing that had no effect on the pump. It was pumping .....just not where it should be. Running low fuel levels in the tank is the worst. The pump will pick up air and/ or overheat. Fuel is the coolant for the pump as well as lubricant. There is a CP4 disaster prevention kit (look it up) that supposedly prevents particulate from invading your fuel system if the pump fails. Though I have not heard first hand experience where someone had a pump fail with that kit installed and what the results are.
