What Fuel Addatives do you use? or recommend? - Page 3 - PeachParts Mercedes-Benz Forum

dogguy · #31 07-14-2009, 05:54 PM

-300CD-T (Calif.)-
At each full tank fill-up:
RedLine Diesel Fuel Catalyst (follow label instructions for quantity to use).
1 oz. of generic two-cycle oil (recommended on Mshop by Larry Bible many years ago) – related to injection pump and the effect(s) of reduced sulfur content in current-day diesel fuel if I recall correctly.

Approx. 247,000 mi. on odom. and no visible smoking on acceleration.

I will put in my vote for the BioDiesel. I used to use Power Service in my trucks before I new about the bio back in 2003. Since then I have used it in 3 of my diesels. I can honestly say that it did make a notable difference in each. Especially in the smell. I hate the "truck stop smell".

In the MB the noise difference at idle was dramatic in my case. After replacing most of the lines I have been using B20 regularly, or around B20 (in a blend). I started out with B20 started replacing lines and filters after a few oil changes... Then I ran a couple tanks of B99 through it. Man.... What a difference. My last tank of straight B99 was at the Central FL GTG. I had people walking up and asking if I was running bio? I asked if it was that obvious? They said yes.

I am a little worried about the IP and a few other things over the long term. So, now I am back to running a blend of around B20. Sometimes a little less, sometimes a little more.

I have run the stuff for hundreds of thousands of miles between my Cummins powered trucks and VW TDI's. But, those IP systems, lines, etc., were much newer. The results so far on the MB are worth it and I will continue to use it.

What does the transmission fluid do for you?

Oldwolf · #35 07-14-2009, 09:42 PM

BD has better lubricity and from what I have read it is better for your IP and engine to use B100. So I don't think you have to worry about premature wear.

B100 is fine for your car keep using it if you have changed your lines ... the only thing down the road is the IP may have to be resealed but regular ULSD will cause this just as fast as B100. My 124 IP had to be resealed 3 months after ULSD was mandated where i live ... Only cost me 100 bucks to have it done.

That is an old myth. In reality, running modern transmission fluids through the fuel system is a sure way to coke up the injectors.....it would be better to not run it. Not to mention the extra-foul emissions the car will spew running something meant to be in the transmission! I'd stick with diesel or an actual diesel-fuel additive. Leave the trans fluid for the trans.

I use type F just for priming fuel filters,my stock,and Stanadyne FM 100.
Been doing it 2 years.

Putting transmission fluid in diesel truck engines goes back to the late sixties, early seventies when truck engines were primarily natural aspirated. The object was to clean the injectors, but it created a lot of smoke, which you probably could not get away with in these PC times. There are many things you can use today. I use LUCAS top cylinder treatment (3 oz. in each fill-up) and it seems to help quite a bit. Bill.

BIODIESEL.

Get out from under your petroleum masters.

Oldwolf · #41 07-15-2009, 09:29 PM

Even though I am using B20 I still want some Diesel Kleen in my trunk to treat straight diesel when I buy it.

rather than lugging around an 80ounze jug of the stuff I am experimenting with different containers to carry one 12 ounce dosage.

I am now trying a 20 ounce plastic Coke bottle. Has anyone already tried this an did it work? I'll check it in the morning, hopefully it won't be a melted puddle of goo.

Thanks pawoSD, I figured as much. My 201 sat up on jacks for about 7 months straight with 3/4 tank of #2 diesel mixed with a small amount of B100 while I completely refurbished the top end of the OM602.911. At first crank, I had some serious nailing. Siphoned all but about 1/8 tank and refreshed with straight B5 (the only #2 diesel available in Portland) and that seemed to help a tiny bit. Took it to the indie thinking the IP timing was off due to the timing chain replacement, but the IP timing was less than 1/2 degree off - the indie left it alone. He says I still have 1500 miles or so to "break in" the chain. In the process of the indie removing the #1 delivery valve to check the timing, I suspect the nailing was remedied - maybe some gunk, water or something else clogging or otherwise inhibiting proper delivery. Now it runs smooth as silk. I think I will look into regularly using a good fuel drier/cetane booster to keep her running in tip-top shape.

When ever I changed the fuel filters in either the Datsun (has the Racor with the large plastic bowl and spin on) or the mercedes I used ATF for filling the filters. I never saw any additional smoke or remember any bad smell. that is a higher concentration than adding ATF to the fuel tank with ea fill up.
Now I have had that old Datsun going on 28 yrs and 455000 miles, so if I have been doing something wrong, I should know by now.

I use 1oz of 2-cycle oil per gallon when I fill up. I buy the Walmart oil in the gallon jug. I have some 8 oz bottles I bought for the chain saw, and fill them and keep 2 in the trunk filled. they have the oz marked on the side, so add accordingly.

I don`t believe the oil co`s add anything to the fuel after thay have taken everything out, for lubrisity.

Does it make it run quicker, faster, smoother and more better? I have no idea

. but if I screw it up, Metric Motors is close by for another engine

. if money can fix it, no problem.

remind me of white enriched flour, they take every thing out, then say they add stuff to make it good for you

i use 2 qts of 15w-40 for each fillup and can tell you for sure it has quieted engine down a lot on idle.also had it that way at emission testing 2 weeks ago and past with flying colors

Brandon_SLC · #45 07-16-2009, 05:31 PM

I'd be worried about all the additives. Why 15-40? Would 30 weight work? I don't understand why this would be better than a dedicated product?

We've had diesels in our family since the late 70's. Back in the olden days, we used Siloo a lot. Truckers used it too. I read that someone did a chemical analysis on it and found out that it was basically Tranny fluid. However, it lacked the dyes and other additives used in regular tranny fluid.

My VW ran well with it. So did the the many Mercedes diesels in the family. I'd add it every third tank or so when the car was newer. As it aged, it prefered having some in each tank. I didn't know about diesel purge back then, I also didn't know that injectors wore out.

Can you still get Siloo? What are truckers using these days. I don't frequent truck stops anymore.
