What happens when you mix diesel with gas??

[ampdavolts]

There really is no magic in diesel fuel. Almost any light oil will serve. Ask Rudolf Diesel. Almost any light fraction will serve fine: the fuel is injected at the desired time. Then it is vaporized by the heat of compression and DETONATES with a terrific shock. Gasoline under compression is the problem fuel. Ask Sir Harry Ricardo, re: The Modern High Speed Internal Combustion Engine.

[ampdavolts]

There is more energy in a gram of diesel fuel than in gasoline. Gasoline is a weak sister by comparison. Diesel fuel needs much heat to be vaporized Liquid fuels cannot burn; they must be put into gaseous form. Gasoline is more easily vaporized than diesel; it does not require much heat to vaporize gasoline, compared to diesel fuels. Liquified butter runs diesels fine, today, as it did also in 1895. Gasoline today is highly engineered to resist detonation, diesel...does not need that feature.

[meangreenf150]

Don't forget to change your oil too. I had a truck come in with 4 gallons of diesel plus 6 quarts of oil in the oil pan. The gas was contaminated with 18% diesel fuel and it washed past the rings and overfilled the crankcase. Next time use a bottle of top engine cleaner or BG. Stuff works great

[Whitehorze]

LOL... The last time I saw an engine making that much smoke an E6 lost a stripe and his job as the generals driver.

[norton996]

A guy I worked with years ago pumped gasoline into a diesel trucks fuel tank because he did not notice the different color of the handle on the dispenser. The truck ended up with over half a tank of gas mixed with the diesel. You have NEVER seen or heard such a noise as a diesel running on a gasoline mix. The cloud was so think you could not see through it.

[davida1hiwaaynet]

One thing to be careful of; if you accidentally make the "perfectly wrong" mix of petrol and diesel fuel will lead to massive detonation. This can melt holes in the pistons.

Diesel fuel is indeed designed to ignite under compression without spark. Petrol (gasoline) is designed to RESIST self-ignition. You can see how these two conflicting traits will lead to some very damaging operation.

[MrKiaboy100]

U coulda used a anti freeze drip into the exhaust manifold

[JAROSLAVAGINA]

clean out a fuel line with diesel fuel? have you not seen the filters a diesel engine normally uses? that's like saying your going to use crisco to clear a clogged sink drain.

creative way to make a smoke screen though.

[99LieCrusher99]

Merchant Mariner?

[99LieCrusher99]

What uniform is Tom wearing? I can't tell.

[xXUSMCGRIFFXx]

Why didn't he just Seafoam it?

[mastersduhgree]

I think thats a multi fuel usage engine.Will run on gas ,diesel,french fry grease,vomit(well ok,,,maybe not that)

[nc1recruiter1971]

I had no idea that this video was going to get this many hits... I shot the video to show my Sea Cadets how the smokescreen was made. The guy who owns this truck jokingly said, "Hey, why don't you put it on YouTube." Well I did and I am amazed at the comments. It is cool to see the old-timers and gearheads that responded to this video. Thank you all for your comments and making this all worth while.

[denp54z]

I use to know an old shade tree mechanic who used auto transmission fluid to clean his old cars gasoline engines out but he just poured a little in at a time directly in the the carburetor air intake with the engine revved up, talk about smoke. I wouldn't dare do it to a modern car engine though.

[MyDucatiGT1000]

@denp54z you can also do that with water at high revs,it steam cleans the combustion chambers,i know it sounds wrong but it works....just not too much at once or it might throw a leg out of bed

[skippytdi]

you cant put diesel gas in anything cause it doesn't exist.

[Dude13450]

@skippytdi technically diesel is gas and gas is diesel. to put it the way my dad taught me, "if they're 5 steps to make gas, diesel would be step 2" all gas is, is a more refined diesel, and all diesel is, is a less refined gas, which is why it has a higher energy output.

[smirnofowner]

@Dude13450 your dad was a wise man

[yamahonkawazuki]

@Dude13450 yup and it starts from crude oil

[polakowykolesz]

you can even boost fuel economy and power by putting about a liter in a normal tank

[BSCHOPPER8787]

FUCKING POSERS

[icicicles]

I'd do this with my Mustang because it had high compression and needed higher octane then the pumps. trick is to prime a gallon at a time tell you find it begaining to smoke then back it off untill it no longer smokes then split the differance.

If you don't have at least 10.5 to1 compression ratio, don't bother. Also note this guy is just lube/cleaning his eng, I ran my car on it. I used 2cycle oil down the carb to do what he was trying to do then top it off with adomized water injection.

[smirnofowner]

@icicicles deisel rates called cetane, its a unit used to messuere the villingnes to ignite under pressure. thats exactly what you dont want to happen in a gas motor. In cunclution, diesel has very low octane and high cetane, gas has wery high octane and lov cetane. If you could make a gas motor run on diesel it would nock the rods from the crank.

[MrLOWSTYLEZ]

what an idiotic thing to do lol theres alot more harm then good that can come from that

[RedResurrections]

white smoke those pistons are glowing

[stopglobalswarming]

If you put even 1 or 2 cups of diesel in a modern car, it may clog your filter, or permanently wreck a fuel injection system or more, especially in a car with high compression.

[MountainDweller67]

The original 'Duece and a Half' trucks had a normally aspirated six cylinder 'multi-fuel' engine that could be ran on diesel, kerosene, JP4, 5, 8, and in emergencies, gasoline. All it was, was a low-compression diesel engine provided by Kaiser. Ran a Deuce for 12-miles on straight-gas once...manifolds were glowing cherry-red when we got back to the motor-pool lot.

[klincecum]

@MountainDweller67 You mean high compression. A multifuel engine's compression ratio is 22:1.

[justin76bmw]

u ever smell fuel injection cleaner??? hmmmmmmmm???

[nawzy202]

Dieles engine run good with gas but you have to calculate yor mixture correctly when you get the right mixture it runs better and stronger then with diesel only

[stopglobalswarming]

@nawzy202 I am a commercial diesel truck driver, and a couple times I have felt the truck start 'gelling" up, and put 1 gallon gasoline in (2 120 gallon tanks, so not a lot, 1 gallon over more than 100 of diesel). That cleared it up pretty quickly once I got back on the highway, and it pulled hard, with a little bit louder exhaust.

[Blaze0539]

lol?



[dirtddoctor]

Cleaned out the diesel lines with JP4 Local Airport 5 gallons mixed into both fuel tanks did wonders. I had been running biodiesel and had some gummed up lines. Jp4 cleaned up everything! plus it had lots more power.

[drakos365]

They used to put transmission fluid in the fuel when I was young to clean out engines. Think I like the idea of diesel fuel better. Either way smokes a lot it would seem.

[wav5000kb]

so.....diesel+gas=awesome smoke?

great i will put diesel in my gas tank too XD

[Torpedoeight]

Doesn't the M37 use a Chrysler Flathead Six; same as all Dodge WC series of military vehicles dating from 1940? They aren't multi-fuel engines. The primary improvement over earlier Chrysler Military Trucks being a NP420 partial sync transmission, river fording capability, improved wiring, and a slightly increased engine displacement.

[Mrtruckboy9]

Just so you guys now usally they are muti-fuel engines if not you a dumbass

[truebassB]

Petrol Truck? I don't even want to imagine the torque and mpg of that thing...

[MrBry329]

o for real man it tripped me out when my friend took a gas gas and disconnected the tank line and ran the gas line to the gas can poured in 120 proof moonshine and that truck was running better than it ever did on gas man talk about fast it was doin 75 plus with no problem before it would take amin to get there that moon shine cleaned everything lmao i love old chrysler products

[215jami]

@MrBry329 Eventually it will burn a hole in the pistons, but it wont feel any pain !

[MrBry329]

my truck can run on moonshine lol 318 1977 original carb carter 2b 

[notanova]

@MrBry329 My slant six does too! 1980 Plymouth Volare all stock!

[zythepsarian]

@MrBry329 i got a '78 2bbl 318, the fuckers unkillable

[Dualshock21]

these military trucks can run on almost anything that burns

[sookoll23]

@Dualshock21 But a Kawasaki KLR 650 will run on mud!

[Dualshock21]

@sookoll23 And my car can run on my piss

[barnesj89]

@Dualshock21 hell, half of what it can run on doesn't even have to burn

[SgtSimp111]

Awesome lol

[nc1recruiter1971]

It is a way to flush the engine AS LONG AS YOU DON'T OVERDO IT!!! This particular demonstration is what happens when you use too much. We were also making a smokescreen for our Sea Cadets :-) You are correct though, it is not a recommended way to flush the engine. The guy who owns the truck is a diesel engine mechanic and a merchant marine engineer. There isn't much he can't do with an engine.

[BlueRice]

@nc1recruiter1971 i remember way back when i told my parent do the same but they pump the gas tank with diesel and the car wouldnt run. had to pump it back out and got it back and running.
