I have been a professional automotive technician for 26 years (Chrysler master Tech and Ford Senior Master Tech), and now for the past 5 years I have been an automotive instructor. I have seen many, many examples of sugar sabotage. I have seen the same thing happen every time on cars that are fuel injected ( most everything has been fuel injected for the past 30-35 years). Here is what I have seen: Most of the sugar stays in the tank, with a small amount migrating past the fuel pump, and whatever filtration there may be on the car. (Most cars do not have a replaceable fuel filter anymore). The small amount of sugar that gets to the fuel injectors stops there in the injectors. For whatever reason, whether its temperature change, size of pintle passages, flow and pooling of fuel at that point, the sugar seems to stop right there in the injectors. This ruins the injectors. They will stop working due to the pintles freezing up inside the injectors and nozzle stoppage. This causes, either a no start, or a misfire if there are some injectors still working. What we have done to repair this in the dealerships that I have worked in was, replace all injectors, replace fuel pressure regulator if equipped, drop tank and clean thoroughly, replace fuel pump, replace filter if equipped, and thoroughly flush fuel rails and all lines. Put new gas in and test drive. Some insurance companies also want the engine oil changed, though this doesn't seem to have any real connection to sugar in gas, its just their policy. These steps have always fixed this issue. These cars come back in for regular services with no long term issues noted by us, or the customer.

Thanks again for the great work. I had an experience with sugar being put in the gas tank. The result was totally different from yours. The sugar hardened in the carburetor, blocking all the ports, jets and valves. I tried rebuilding it, but after removing the sugar build-up, the metal parts were so severely corroded and pitted that much was not salvageable. I bought a junkyard carburetor and built a good one from the best of each. Then I drained and flushed the fuel system and installed a new filter.

Are you sure it was sugar? The corrosion would suggest it was salt. My experience with sugar in the tank was I bought a ‘95 Kawasaki Ninja motorcycle.

Years ago I came into possession of a 1973 Buick Regal with a 350 V8 that had under 100K on it. When I received it I know for a fact that it had had a 1/2 pound of sugar put into the gas tank 6 months earlier, with approx 30K miles on it since the sugar. The PO had told me that Within a month or two the carb had to be rebuilt. It ran fine when I got it, I even used it to tow my boat back and forth to the Colorado River. Then on my 3rd trip towing the boat, the car started losing power and running really bad. Wouldn't hardly idle and was making a lot of valve train noise. After getting it home I pulled off the intake manifold and found 3 or 4 bent push rods and either stuck or collapsed hydraulic lifters, about 1/2 of them were toast. Replaced the bent rods and put all new lifters in it, put it back together and drove it for another 3 or 4 years without any more problems. Then the person I sold it to drove it another couple of yrs. I have very little doubt that the sugar was the cause of both the carb and the lifters going bad. Not the catastrophic failure that I had always been told would happen, but had I not done all the work myself, it would have surely sent the car to the junkyard. Any way, it was great to see this put to the test, Thanks for all the great videos PF!

[@timbean7849]

some-one put alot of sugar in my 1963 ford truck. and it glued my intake valves shut, to where it bent my push rods when I tried starting it the next morning, after I replaced them, then I threw a rod not long after that, the piston had mysteriously shattered and and put a hole in my block below the water jacket, leaving the rod cap on the crank and leaving me good oil pressure, and no coolant leaks so I drove it the 200 miles home, it shook like a paint shaker, and bolts fell out everywhere, and had to be push started the last leg of the journey when the starter fell off and got broke, I welded the hole up in the block and replaced the rod and piston, using the old bearings, and drove it another 10 years before replacing the engine at 508,000 miles, and yes its a big piece of crap, and I still drive it, and its my 1st ford and Ive owned it for 34 years and put 400,000 miles on it myself and only had to tow it home once

[@kevinc.8869]

I had somebody sugar my gas tank many years ago. They must have dumped a 1 pound bag in there. Like here, the sugar never really broke down and remained at the bottom of the tank. It did make it into the electric fuel pump and it ruined it. The only way I found out was when the vehicle started losing power. I had to drop the tank and vacuum out what was left. New fuel pump and filter and the engine is still running fine today.

My family owned a foreign car dealership, in a town of about 50K people. There were no other shops in town which repaired foreign cars. I recall a 1959 Jaguar XK-150, which was at the high end of the price range of street/highway use sports cars. Someone had put about a 5lb. sack of table sugar in the gas tank. The Jaguar engine, which was a double overhead camshaft type, had what we called "swallowed a valve." This means that one of the intake valves failed to return to its upward position, resulting in a piston striking the stuck valve. This destroyed the piston and valve, and severely scarred the cylinder walls, requiring a total engine rebuild. This cost about $1250 (1960 dollars). The gas tank, dual carburetors, and fuel pump and fuel lines had to be totally cleaned out. The tank, when removed, still had about 3/4 of the original sugar. The car was driven less than 50 mi. after the sugar was put in the tank. This shows the damage which can be done by sugar in the fuel.

If your story actually happened, though, I wouldn't be surprised if your buddy got scammed into covering a fix for something else that was already wrong with it.

While I was an apprentice, and the senior technician was baffled, we decided to cut open the fuel filter... completely clogged with sugar, fuel regulator, injectors & catalytic converters all shot!the engine it self would have safe, except for the buck shot dropped into the throttle body.long story short her ex boyfriend had a rather expensive bill to settle, and time to serve!

[@rickshook1446]

try it with powdered sugar. will plug up the carb big time

Interesting. How about a test for fuel additive engine cleaners or oil additives like molybdenum etc. There are so many products out there.

[@leewarren]

Did you look at the fuel filter on the mower pre and post sugar addition?

[@dennymambo]

Interesting. I always thought it was just to make a huge, time consuming (and therefore expensive, for most ppl) mess. The idea being for the sugar to foul and eventually block filters and jets/fuel injectors.

[@ProjectFarm]

Thank you!

[@rogerc.roberts4705]

My experience is the LONGER the sugar is in the SYSTEM the more build up and CLOGGING in fuel lines and oil passages. Your short duration test will not show this. Don't even think about putting sugar into a fuel injection system as injectors do not tolerate any form of buildup!

[@WillN2Go1]

Another brilliant video - every guy who's lived in the past 130 years has wanted to see this. Thanks. I was curious where sugar crystals were on the Moh's hardness scale. One 'source' said "Hardness according to Vickers for sucrose crystals is equal to 755 MPa (Bubnik et al., 1997)." [I don' t know what this means]. I remember reading that the Desert Rats during WWII in North Africa - if they couldn't blow up or burn an enemy vehicle they put.... and I remembered 'sand'. They put sand in the gas tanks. I don't want to ask the question because your lawnmower sitting in your garage looked so unsuspecting and innocent.

[@DougDaCosta]

The old VW air cooled carbureted Bugs didn't come equipped with a fuel filter. We had a Bug towed into our shop on day, that had a frozen engine. The first assumption was that a main bearing had spun and locked up the crankshaft. Turned out to be sugar in the gasoline. The acceleration pump actually had particles of sugar at the nozzle. The pistons were seized to the cylinders because the carbon of burnt sugar had taken up all of the space between the pistons and cylinder walls. I tasted the carbon with my tongue. It had an obvious sweet taste. It's the only example I've seen of a sugared engine.

[@ProjectFarm]

Doug, thanks for sharing this experience.

[@buddyclem7328]

VW bugs do have inline fuel filters. The owner of that one removed it. They paid a high price for being a cheapskate!

Thanks for sharing.

[@robertlong1693]

That would be my plan of action also!

[@ghostlygrimrapper]

How about running straight e85 through the mower and seeing if the carbon build up is worse? Also see what it would do to the carb. We always hear about how bad ethanol is for smaller engines I think this would be a great test.

[@andrewmcewan9145]

Tyler G if you let ethonal sit for an long time (over the winter) the water separates and the ethonal turnes to gell cloging the carb.

[@donhepler294]

As a kid, I was among a group of students stranded 50 miles from home when the bus in which we were riding stalled and would not re-start. Sugar had been added to the tank. It may have been a diesel bus,however. We had to wait until another bus and driver could reach the scene of the breakdown. I always wondered about this as chemically sugar is not very soluble in petroleum solvents.

[@ProjectFarm]

Thanks for sharing!

[@AngeliqueKaga]

Once again, you did a nice job.

[@rickybattle6230]

Let the engine set over night, the sugar will harden, maybe then the piston rings will stick to the cylinder wall also causing the valves to stick seizing the engine.

[@johnmayer5920]

Sugar doesn’t seem to dissolve in gasoline very well but I wonder if you added sugar to the oil in the crankcase of that with gum things up right and proper

[@ProjectFarm]

Thank you for the video idea!

[@buddytazzer]

I'm with you on that one! Definitely sounds like it would get interesting quick.

[@logik316]

Adding any kind of crap to the crankcase would cause very expensive damage. However, you have no way of getting somebody’s hood open without first obtaining access to the passenger cabin and the hood release lever, whereas even some modern vehicles don’t have locking gas hatches.

[@neededknowledge]

I'm suspect something similar may have happened to a vehicle I own. What I found in the injectors after pulling the rails and them out with something I've never seen before and I can only imagine would be sugar.. why am on KZbin right now looking for sugar videos inside injectors / motors. I'm a big fan of B12. I would like to see you add the B12 to see if it intensifies or cleans the problem. Thank you for your time and greatly enjoy the content.

I suspect the better additives will work well, I'll keep an eye out for the video when you get enough suggestions. ACCORDING Delco puts out a good cleaner but it is pricey.

[@ILEFTCAPS0N]

That's interesting. I've been hearing sugar will destroy an engine since I was a kid. Have you tried using a simple syrup (3:1 ratio of sugar disolved in hot water)?

[@farmalmta]

Ding, ding, ding! We have a winner! Yes, simple syrup plus emulsifier to bind it to the gasoline or diesel and the engine is screwed. Granulated does nothing but cause sludging problems.

[@carlo89]

I saw on Thomas the train about the sugar in the tank thing when I was a kid, that's why I've always believed it. Hahaha

[@ProjectFarm]

Great suggestion!

[@jamessellers6276]

Some years ago I read an Army field manual that was printed in the 1950s or 60s that had to do with sabotaging equipment behind enemy lines. There was a chapter devoted to adding things like sugar, acids, etc, to the fuel tanks and then running the engines for several hours and see what kind of damage was done. The tests were done in a laboratory and well documented. At the conclusion of the tests it turned out that it was either Linseed or Tung oil (I can’t remember which) were most effective and did the most damage. This was because they were very soluble in gas or diesel fuel so traveled easily through the entire fuel system to the combustion chamber where it would gum up the rings something fierce. What happened after the engines were allowed to cool to ambient temperature is they were locked up solid and required a complete overhaul to get them unstuck.

[@ProjectFarm]

Thanks for sharing.

[@rjo49]

It probably wouldn't matter much which of those you used. They are both drying oils and should cause equivalent damage, maybe over slightly different amounts of time.

[@alro2434]

Thanks! Worked on a Citroen with linseed oil, intentionally added by the owner who thought the oil companies conspired against owners with an inferior product that needed his linseed additive help! Don't know how much he used, but had been doing it for quite a while and it was a real mess, gummy sludgy filter.

[@JonathanGurgul]

What would happen if you ran an engine with Gallium in the engine oil? I’m curious to see what would happen to Aluminum engine components. Considering its low melting point, it would stay liquid under normal engine operation.

[@got2kittys]

That's really devious. Powdered, it would probably be a nightmare, completely totaled.

I have no idea what additives might remove the sugar buildup. How about, in your own immortal words, “Let’s find out!” Your videos are by far my favorites! Thanks, Todd!

[@ProjectFarm]

You are welcome!

[@dragzgaming]

Ethanol.... after removing the tank and filter. Then let it dry or you will dissolve the rest of the car or seize the engine anyway lol

[@noxious89123]

I'm curious to know what would happen if you added some water to the fuel tank (to dissolve the sugar) and also mixed in some ethanol (to absorb the water and make it miscible in the fuel). Obviously you'd need to use only small quanitites of water and ethanol in the gas othewise the engine probably wouldn't run. Unless I'm mistaken, without the addition of ethanol, the water would sink to the bottom of the fuel tank and wouldn't mix with the gas. But then the sugar is in the bottom of the tank too!

[@douglasmills6357]

the sugar will dissolve eventually t y piece out..

[@rosen9425]

That should create an emulsion of fuels, water and sugar. The worst part, I'm guessing, is the clog potential of expensive shit to replace. Caramel in the combustion chamber might be a bad thing also.

[@dufftruck6]

would it be worth putting some marvel mystery oil in it to see how much the oil could improve the compression ratio

[@ProjectFarm]

dufftruck6, Seems like a good test. I was thinking about using a product specifically marketed for compression improvement, such as Lucas or Dura Lube. What do you think?

[@dufftruck6]

yea the lucas would be a great idea because i have a old diesel truck which has lost most of its power over the year and I'm sure its just from blow by and valves not setting properly

[@richfarfugnuven6308]

Project Farm archoil 9100 might be interesting as well.

[@DENicholsAutoBravado]

I've already tested Lucas Upper Cylinder lubricant for how it effects MPG, but I haven't tested it's effect on combustion pressure. The trouble is, I like it so much, I don't want to go without it. :)

[@Redhawk85]

I didn't test the compression ratio in mine - but about a capful amount added to the fuel as well as a capful to the engine oil seemed to help it quite a bit. The engine runs very smoothly and it starts immediately on the first pull even after being in cold temperatures for weeks. While it doesn't cure all things it does add to engine performance (probably engine life, too), which is why I'm a fan of it.

[@vincentxgolden6624]

I haven't watched your video on chem tool but I think that's the one I would prefer and yes I would talk the tank and clean it clean the filter or change it and possibly run some fuel stabilizer through it

[@ProjectFarm]

Thanks for the feedback.

[@Mariazellerbahn]

In early days, sugar was added to a gas tank as a spiteful way of disabling a car. Sugar does not disolve in petrol so would stay granular and you would need to add a lot of sugar in the hope that a few grains would get picked up and block the carburettor jets or fuel injectors. It is a complete myth though as the fuel filter would stop the sugar before it could cause any blockage but eventually, the filter would clog but it would take a very long time.

[@lilanti-depressants5660]

Doing that experiment must've had *sweet* results.

[@ProjectFarm]

[@brucebehnke3227]

Drop tank to get sediments out change fuel filter& run sea- foam in it 😳 that will fix it

[@snappertight]

I was always told that if an engine sets too long and seizes up you can dump transmission fluid in the plug hole and free up the piston. My dad did this on an old engine that sat for many years it took a while he went every day and bumped the engine and after a few days it turned over he was able to get it running. Not sure if it will work on one that has seized from lack of oil or got to hot but you might try it. I'm sure it would have poor compression after but worth a try.

[@ProjectFarm]

Leonard, Yes, I've heard that ATF works well for a seized engine from sitting! Thanks for watching the video and commenting!

[@MuttiFPS]

Project Farm I think this would potentially be a cool video to try!

[@ProjectFarm]

Thanks for sharing!

[@laurenceperkins7468]

In the old days most engines used a settling bulb instead of a fuel filter. Sugar is light enough that it often doesn't settle out like sand and grit does and can get carried up into the carburetor. What happens from there depends on the engine, ranging from significant carbon buildup like you saw to plugging up the carburetor jets, or gumming up the valves. Seizing the engine is a bit of an exaggeration, but it's definitely not good for it and depending on what gets blocked up it can take quite a bit of effort to get it cleaned out again.
