  • Black soot in tailpipe

    There is a thick layer of black soot in my tailpipe. Is this normal? It looks to have built up in the 12k miles or so after my conversion.

    Man, me too! mine's got so much soot my finger turns black when i touch it. Come to think of it, there's soot all over the bottom of my quarterpanel. I really need to wash my truck and clean my tailpipe. Is it true there is much less carbon monoxide or (Oxide?) but much more nitrous oxide from the exhaust of WVO?

      Soot

      I to had this problem after 9,000 miles on grease.For me i think it was from Idling,it did't burn hot?Any who We don't Idle any more(i bought 12v power source for my boys DVD player.Bug and tar cleaner works great on it with a little elbow grease.Oh yes there is more nitrous oxide (about 15-20%)but 80% less carbon monoxide.You should sleep well at night Knowing that your 7.3L is cleaner than a Ugly little Prius..grease out

        Soot in a diesel tailpipe is normal. Part of having a diesel. In fact the more the better!! Okay maybe not. But really take a look at some of the hi-po diesels and they will belch clouds of black smoke without an ounce of WVO or even bio.

            sulpher additive

            I've been adding a Sulpher additive to my WVO,the GreasyX now smokes like my cummins (old School) .Also a good way to stink up the WVO(less Questions,etc)....grease out

              That kinda defeats the purpose of the "greener" fuel...

                Guys -

                Sounds like his accumulation has increased dramatically after the kit installation. He is obviously familiar with the black smoke/soot that would have accumulated before the kit was installed. (At least I hope so).

                I was expecting less black smoke from the vegi... and I completely wrong?

                Don't get me wrong, I have a DP Tuner with a smoke tune for shoing off a little... but I didn't expect more smoke with the vegi.

                  sulpher a no-no?

                  Clay,do you know of any synthetic addatives that could do the same things that sulpher does(don't get me wrong,but my truck originally ran on low-sulpher diesel),i was worried it was missing something.Not trying to deplete o-zone just don't want to break my truck!!P.sWe heat our home and office with a Ag Soltions B-150(burns WVO,UMO,ATF,.ETC),So we are going way out there to be green($$$ and technology)......grease out

                    Your adding it to make it smoke and smell different?
                    I don't understand.

                      It does smoke a lot if you drive around town with it... combustion just isn't hot enough without the load I would guess.

                      On the hwy I see virtually no smoke even under load.

                          haha too funny.

                          Only prob with stacks is that you can't give the yuppie next to you with the top down a mouth full of combusted grease

                          sometimes I feel bad but the whole family gets a laugh "Oh dad you got that guy good" hehe

                            Yeah its nice to be able to smoke em sometimes but like today i was sitting there trying to merge into traffic..i was stopped and looking back over my shoulder and the traffic was just flyin around this curve so when i saw a little gap, i hammered the skinny peddle and i should have powerbreaked it cause the turbo lagged like crazy and meanwhile i was blowing a 5" stream of soot so thick this little car behind me completely disapeared...completely. I mean they had to wait fot it to clear before they could see...i felt bad but i was laughing too. Oh and it was dead still out this morning, no wind at all so that coud lingered around for a long time it seemed.
                            this particulare custom program i have is made to lag the turbo a little at take off so it will smoke...i have been playin around with it but that turbo lag is anoying so i am going to put my other street tune back in, it will still smoke but not as much and it will not lag at all.

                              sulpher additive

                              I was adding it because every time I went to canada I was getting 20 Qs about what I was running for fuel,I don't like the Gubbament in my Business.Also noticed less clatter on start-up with it in the diesel tank.I guess I'll throw some Lucas in the diesel tank.What do u guys use to make up for ULSD in your diesel tanks?.................grease out
