Cold start issue.
This past winter, I have had an issue with my 6.0 (2003 with 36,000 miles)needing to warm up a little longer before it runs right after a cold start. I only mention this because winter made a return visit here in the midwest today. I know there where colder days in winters past that I was able to start the truck and drive away with no issues. Now when it is below 20 F the truck acts like it is not getting fuel until things warm up. It starts, but when you put it in gear, it misses badly. I am still about 10,000 miles from my next scheduled fuel filter change. No codes are showing up. Anyone have any ideas? Thanks in advance for your help.

maybe fuel
I live in central MO. I know what you mean about winter returning. I not sure but they are probably starting to change to summer blend fuel. It has been so warm during March that maybe your fuel was summer blend and it was thicker than normal. I would see how it does when it warms up. You might even plug it in and put in the garage to warm the whole truck and see how it starts. Just a suggestion. Good luck

Maybe I'm just lucky....
Just bought my 03 in Feb. I'm in WV and you're right...it was DAMN cold then and is supposed to get some snow this weekend. EVERY time I cranked it after I got it home, she started right up with no problem and no smoking. I have yet to plug mine in. I've seen others say that theirs starts hard in cold weather...not mine...knock on wood!

What weight oil do you have in it? If 15w40 it will do this until the oil thins out (warms up) This is one of the reasons they recommend 10W30 below 32 deg.
Yes here in Michigan it is going to 15 deg tonight.
It was 78 deg 2 days ago.

Also to test the truck properly to rule out any other problems or a bad injector the dealer needs to keep the truck overnight in order to do a cold soak start and cylinder contribution test.
Hope this helps

I agree with Blackhat, I just had my truck re-flashed for that very reason. It runs better than ever now.

I would like to add some information to the mix here. I worked on a project with Ford Power Strokes. The injectors were failing and we came up with the idea that the additives in engine oild were cooking out inside the injector because the injectors get so hot. After many tries we came up with an additive that will clean them 86% of the time. It doesn't work 100% of the time so I put money back guarantee on it. But I know from personal experience that it works most of the time. Even when it didn't work it was able to give a clear code on many of the other injectors. We would have trucks that showed 5 injectors bad or needing replaced. After teh additive it would show only one. I would like you guys to try it and post the results bad or good. I am available to answer any questions. My background is in Lubrication Engineering so I am not a mechanic. I was called into the project to figure out what was happening on the lube side of things. You can get it at www.lubricationspecialties.com it is called Hot Shot's Secret. Let me know what you think.

Hello Lube Specialist. I think I like the sound of this. I see to use 64 oz in a 5 gallon system, so I assume to use about 48 ounces in the SuperDuty with 3.75 gallons of engine oil (or so). My question is this...do I add this product to the 15 quarts of 15W-40 already in there, or substitute engine oil with HSS, using less oil, and replacing it with HSS? *How many ounces in a quart?* Thanks. Joe.

By the way, I haven't had any issues with my truck yet, do I use HSS as preventitive maintenance, or just if there are problems? Do I need to use it at the recommended level for maintenance? or just at that level if there are problems with less used for maintenance? Joe

Joe, Your math is right. It would be best to replace the 48 ounces of oil with HSS. But if you don't have a problem yet the best product to use is the 480m Ultraguard. The HSS was designed to fix a problem. The 480M was to prevent it. If you use a good quality oil and a good additive in the fuel you will avoid the problems with the injectors.
