IS it true that kerosene is added to diesel fuel. . . - Page 2 - PeachParts Mercedes-Benz Forum

it shouldnt ever get cold enough to do that in san fran.

winter diesel is plain old diesel that has less oil in it to keep it from gelling in your fuel lines. all gas stations ahve it in cold ares there is just less oil in the diesel in the winter time. no kerosene is added becasue that would mess your injectors up casue kerosene is the scum and is alot heavier fuel.

Not true. Mercedes recommends a small amount for a winter mix (says so on my fuel door). I've never heard any recommendations for kero (although I know it's alright to burn, just not enough lube for me).

Actually "winter diesel" is normally a blend of #2 diesel and some #1 diesel, which is similar (but not identical) to kero. My owners manual gives recommended ratios of #1 to #2 diesel depending on temperature but does not say anything about mixing in gasoline.

Wow. Getting kero might take some work.
Frankie

The general concensus of those who have actually tried it say gas is better to thin WVO than kerosene.

Weird how the different years diesel Mercedes owners manual can differ so much on the recommended (or not) use of kerosene v. gasloine.

That's for finally answering my Q about the thinning!
As for my 1984 300 SD owners manual; page 91
At very low temperatures the fluidity of No.2 diesel may become insufficient due to paraffin separation.
To avoid malfunctions, No2 diesel of a lower cloud point is marketed during the cold season.
At temps below 0 deg/32degF use winterized or No1 diesel only. If not available a certain quantity of kerosene may be added. Mixing only to be done w/i the cars fuel tank. Kerosene has to be filled in before the diesel fuel.
Engine power may drop according to the proportion of kerosene. For this reason, keep percent of kero to a minimum neccessary by the ambient temp. . . . Table. . .Adding kerosene to No 1 diesel is not recommended even at low temps.
Is that helpful to anyone?
All I have in this area is Calif ULSD diesel No.2 and biodiesel too. Plus my WVO.
According to the chart, looks like I will not need kero/nor gasoline for San Fran. winters, even Mark Twain's coldest winter.

Refer to Jadavis (above) table is identical to my owners manual.

some benz manuals mention mixing up to i think 25% gasoline in the event you are caught in very cold weather with summer diesel fuel.

the newer ones though dont.

i have run kerosene in my diesels in a pinch to get down the road to the next diesel pump. #1 heating oil too.

no ill effects noted.

Just my 2 cents, but I run about 85% wvo / 10% kerosene / 5% gasoline, along with some cetane boost and a touch of biocide. Been doing it for about a year in my ford with no problems, the benz I just started using it in recently, but so far, no ill effects.

Frankie · #24 10-29-2006, 11:33 PM

Sounds like a good recipe and I use the biocide on the WVo too, but I wonder
and as a nurse by profession, I would want to know, if the engine gets messed up in 5-6 years(just hypotheically) WHAT and which ingredient contributes to the engines' demise?? I've been "researching for 3 months and still don't know what mix WVO safely works w/o sucking power from the engine. I want to eventually use as close to 100% WVO esp in the summer.

THAT is the question too isn't it? So many people are "carefully" trying different recipes for their own experience in that effort to keep the engine good. I respect all peoples efforts! But. . .Nobody can agree on ONE recipe, one way to prove WVO use benefits to the engine longevity. See, biodiesel is proven and recognized but there are too many factors to mess up the WVO. I don't know the biodiesel effects on eng longevity tho.
BTW, where are you getting your kerosene, Biglex??

My 87 specifically says not to because it can lead to plugging of the Trap Oxidizer...you know...that thing that they removed under recall! If that was the only reason not to then a little as needed for really bad weather or WVO should be OK.

If you ever have to run straight kerosene add 2% canola or soybean oil to it to make up for the lack of lubrication. (About 2 quarts of vegetable oil in 20 gallons of kerosene.)

Ah so your in SF, then DONT WORRY ABOUT GELLING

Im in south san francisco, up in the hills borderline daly city. So it gets down to 30F sometimes in the night/morning. But even with B100 in the tank of any of the diesel cars they dont miss a beat. Only smoke a bit more then if it was warmer.

Secondly kerosene isnt available in the SF area, only place i know of that has it is san jose in the industrial area. So dont worry about it, a mix of 80%veggie and 10% diesel is just fine for the SF bay area as it rarely gets cold over here.

firemediceric · #27 10-30-2006, 06:30 AM

Biglex,
I'm doing the same as you in my '99 Ford F-350 since April and '81 Mercedes since I got it in July, except I up the kerosene to around 20%. So far, so good.

SootyPast · #28 10-30-2006, 07:58 AM

Redundant I know... I have run 100% kero in a pinch in my 2006 jetta pd tdi. Poor performance and noisy. My mb manuals say up to but no more than 50% Kero w/ #2. I have run a ford 7.3 on straight automatic transmission fluid for well over 10k miles. Please don't ask... The issue is longevity. Take your fuel of choice and put it in a mason jar half full outside in coldest ambient temps. You could play around and see what is acceptable and roll.

DieselCJ · #29 10-30-2006, 09:55 AM

From page 97 of my 1986 190D 2.5 Owner's Manual:

0* C to -10* C (+32* F to +14* F) = 70% #2 and 30% Kerosene.

below -10* C (+14* C) = 50% #2 and 50% Kerosene.

"Kerosene has to be filled in before the diesel fuel."

"Under no circumstance should gasoline be mixed with diesel fuel."

Isn't it COOL that we don't need a sterile laboratory to conduct gelling test in clear bottles? My neighbors looked at me like was nuts, at first but they are all cool and some are interested too.
Hey everyone, Jadavis has a website, check this out! fryerpower.com
It was stellar to bump into that, I need viton O-rings for my tank too.
FireMediceric- notice any power changes on your engine from the 20% kero? Is it noisier?
I'm trippin' over how different the manuals are. Mine has no mention of gasoline use.
