Changed Oil = Black Smoke...
Okay...here goes. Switched to Amsoil 5x-30 Heavy Duty Diesel FROM Rotella 15w-40. Never got any black smoke from the pipe until this afternoon. Fired the truck up, let it warm up then went for a drive.
Romped on it and black smoke filled the street. I let off the throttle and a huge black "poof" came out.
What is going on??? I have never had this happen before. Some say that the Amsoil is "cleaning" the inside of the motor. True?!?!?
Thanks y'all!

Without adding more fuel (chip) about the only way to make them smoke would be not getting enough air or poor fuel atomization. I don't claim to know anything about amsoil, but I wonder of that 30w is too light viscosity for the high pressure oil system to build enough pressure?

man, i think i need to change my oil out to that... 
in all seriousness, Amsoil is not rated for use in powerstrokes, as it does not meet CI-4 standards, and it does not have the shear strength to handle 3000psi of oil pressure. i have ran it in my truck for a few thousand miles before i knew about this, and it hasn't hurt it. there are plenty of people out there that also run amsoil with no problems.
an educated guess is that the thinner oil will flow faster to the injectors, which travels into the oil fill ports faster and more oil can fill into the barrel before it is compressed. however i believe that the 30w is not thick enough to support the pressure of the crankshaft and rods on their bearings, which can lead to premature wear. that is why i am staying with 40w oil. run it if you desire, and get an oil analysis done after a few thousand miles. see how much metal particulates there is in the oil.

i too have run amsoil 5w-30, as it was recommended to me. however, the truck already had 100,000 miles on conventional 15w40... the truck burned a whole lot more 5w30 than 15w40 (always used some oil). i switched to amsoil 15w40 and it seems to hold up better.as for blue smoke/vs black smoke, i know those guys are right... but who knows?

Thanks y'all! It is BLACK smoke out the rear w/o question.
That really sucks that I didn't catch that CI-4 standard for the oil. Good to hear that you didn't have any problems with the Amsoil Strokin_it7.3. I have already ordered a Blackstone Lab kit for the oil testing.
The truck has always been run on Rotella 15w-40.
Thanks again!! Anymore info would be great!

DSLDRVR- good info- thanks. Seems that most PSD's don't like the 5-30 HDD Amsoil. When I went to Dieselman's page (http://www.intellidog.com/dieselmann/powers~1.htm) he has information stating that the Amsoil 5-30 HDD does meet the requirements for the PSD.
Me thinks more research is needed....
I'll post later today after I drive it and heat up the truck. See if that helps....until then I'll make the enviromentalists wheeze in my cloud of smoke :-)

I agree, I think it is only an option for very cold weather operation personally. summertime our tucks seem to thrive on the 15w40's. I personally do not use the Amsoil in any form, but not because I don't think they make good oils.
Elevated iron seems to be the norm for the use of the HDD 5w30, but I also do not think it is due to lack of film strength.

"Q. I have a 2001 Ford F-350 Pickup with a Powerstroke Diesel with 7000 miles. I'm getting ready to change over to synthetic oil. What AMSOIL motor oil would you recommend to use?
A. AMSOIL Series 3000 5W30 Heavy Duty Diesel Oil is our premium top of the line product. While there are best uses for both our Series 3000 and our AMSOIL 15W40 Diesel and Marine Oil, Series 3000 is our recommendation for the Ford Powerstroke engine. It surpasses the API Energy Conserving Rating requirements designed to provide significant fuel savings. It has highly effective anti foam agents to prevent oil foaming. Series 3000 offers better protective film at higher temperatures than conventional SAE 40 oils while retaining fluidity at subzero temperatures."
I am sure that they want to sell all the oil they can...but it does address the anti-foam portion of it. Not sure that I will run into subzero temps in Greenville, SC....but hey...who knows.
