Just picked up a gallon of Marvel Mystery Oil at Wally World which I like to add to both my diesel and gasoline from time to time. I noticed a new label added to the jug that said MMO did not meet the federal low sulpher requirements for 2007 model diesels. Any idea how many other additives won't make the cut for new trucks?

 

Unless you are planning on getting an 07 who cares. I'm sure most of these additive companies will come up with formulations that will meet the new low sulphur mandates when "Big Brother" says no more of the old formula for any vehicles and it will happen just like unleaded gasoline. It is interesting that for aviation you can still get low lead avaition gasoline, of course it is dyed a different color.

I tried emailing turtle wax(owners of MMO) a couple of weeks ago regarding this. Still no response. I'm still running it on my 01, and will keep doing so.
