sounds like you got ahold of an older bottle. . .all the ones I find are 2007 emissions compliant

 

It wouldn't surprise me. I will pay better attention next time.

 

Went to get more MMO today. The larger bottles don't state whether or not they are 2007 compliant. I posted a question on Marvels website asking about this. Their reply:

Scott,
Current MMO is not 2007 ULSD compliant. It is strongly advised not to use MMO in 2007 ULSD engines.

They didn't say what effect it would have on the engine tho.

 

so are people running this in their 07 rigs?

 

I can find the bottles that say they are 07 compliant, but mostly what this is refering to are the newer 6.7Lengines with the filters and EGR where as the 5.9L doesnt have this. so even though you have an 07 go for it.

 

Im gonna try it next fill up. I just filled up tonight so it will be most likely 2 weeks or so. Im lookin forward to seeing how well it works.

 

I have been using the usual mix in my truck for two weeks and my truck idles alot smoother, my mirrors used to rattle like my stereo did. It vibrates like a gas truck does.

 

so, I had planned on using your brew in my 6.7L when it finally gets delivered.
Are you saying they do make'07 compliant MMO orshould I just run the PSD solo.
Should I substitute something else for the MMO?

after runnin just PSD in my 93 CTD. I cant even smoke another motorist with the exhaust!!!

a ford ranger cut me off sat so i pulled up just enough to blow smoke in his open window. put it in neutral and reved it...NO BLACK SMOKE!! dang I was pissed

I will back up that PSD cleans the system well . have not tried the MMO in it.

this 93 smoked black like an old coal stack till PSD.
