  • I've had a lot of requests to test diesel in the crankcase of an engine. Will it cause damage? Is it an effective crankcase cleaner? Can it be used in an emergency oil substitute? Let's find out! Thanks for supporting the channel! https://www.patreon.com/projectfarm

    True story. First hand, so I know it's legit. Back in the late 70's I worked at a Mopar dealer. (SE MI) One of our regular "wheeler-dealers" brought in a 76 New Yorker 440.. all sludged up. Rockers were squeaking on it an almost no oil pressure. He'd bought it from an old farmer who had NEVER changed oil. He was going to drive it to TN (about 500 miles) and flip it. I personally drained the oil and put a new filter on it. Let it down and he brought out a 5 gal jug of Kerosene! And filled it up. I was in total shock! He drive it 500 miles, pulled into Taswell, TN and got an oil change. Bill claimed he'd done this many times, to clean out an engine. Wouldn't have believed it were not there.

    I have a 98 Dodge 3500 with a 360 Magnum gas engine with about 75,000 miles on it. It sat for quite a bit I'm not sure how much but it developed a top end knock. I had an old mechanic tell me to drop the oil and run a gallon of diesel for 4 to 5 minutes and then replace the oil and filter. I did that and the truck ran better than ever before until I made it to the gas station and blew a timing cover gasket. Replaced that and it seems to run better now than before the diesel flush. Still have the top end knock. When i dropped the diesel I noticed a lot of sludge and solid particles. I did not notice any metal. The truck is not a daily driver and work well enough to get a load of gravel or pull the horse trailer.

    The old Ford Rangers used to get a build up of gunk right in front of the oil pick up, and then the top end wouldn't get lubricated. So if you see and old Ranger for sale cheap, and the seller says it keeps throwing timing belts, all you need to do is clean out the oil pan and you get a good truck for cheap.

    i KNOW THAT DIESEL FUEL WILL WORK ON OLD 80'S AUTOMATIC GM TRANSMISSIONS,IN FACT IT CURED A SHIFT PROBLEM ON ONE.

    Can you run a lubricity test on multiple oil to diesel ratios 1:4 and 2:3 using different motor oil viscosities ranging between 5W-30 to 20W-60? I'm curious to know the minimum oil to diesel viscosity ratio tolerances to flush sludge from an engine without causing any damage when campared to plain 5W-30 motor oil. Will you try it?

    Old 6.2 diesel 230K miles. Drained oil, filled with diesel, ran 5 min cleaned out and changed oil 2 times in a week. Not sure if it made a difference but made me feel better about the abuse the engine had in the past, another 100 K so far. I was afraid of ports getting clogged, but no issues. Keep up the videos. Thanks.

    In the past, I have drained all the oil. Did a 50-50 mix of diesel and thicker oil than specified . Pulled the injectors and cranked for a few seconds. Let it sit and repeated every few minutes. Then started the car and ran it for 1 minute.After that I drained everything. Added only diesel, pulled the injectors again, and cranked for a few seconds. Then drained again.I never noticed any metal flakes but the first 50-50 run comes out black, the last drain of the pure desiel usually game out grayish. And the engine is generally much cleaner.I then add the recommended amount of oil and change it again at half the miles just in case there is residual diesel still working its way. Does this make a difference? I have no idea, my father told me about it, I adapted it to the way I thought might harm the engine the least and give it a good clean.Anyway, thanks for the content!

    I bought a used 75 Ford pickup. I don't think the guy ever changed the oil, it looked like tar. I changed the oil and filter a few times after going about 100 miles and the oil would be black again. Then I added a quart of diesel and drove it about 100 miles. I let the oil drain overnight and after that, I could go over 1,000 miles and the oil still looked good.

    I used Diesel to clean my bmw 1.9 77kw engine. We did let it run untill motor made first ticking sound and stopped the engine.. After that drained Diesel ou and it was black as night. What came next suprised me.. After 10000km we trained out oil what still looked like honey.

    Back in the day, people would spray glass cleaner down the carburetor thinking it would reseat the rings, and also folks would drizzle water down the carburetor of a revved-up engine thinking it would remove carbon?

    It was common back in the day to use diesel or solvent but just let it idle!

    Hi i dont understand in the beginning you said just to clean your engine with diesel . so if you want to clean your engine with diesel you can add diesel run it for less than a minute its more than enough to to clear carbon debri etc .then flush the diesel and add fresh oil and filter . no need to run it till its damage your engine . even you can add diesel and simply drain without turning on . or even just give a small 2-3 quick ignition. as far as my knowledge.

    Project Farm: I was reading an old original WWII Jeep engine manual a long time ago and there was a page with a lubrication table for various ambienttemperatures. There were no multi-viscosity oils back then, so they indicated one weight for hot temps (like 30W for 90 degrees), another for average temps (can't remember exactly, something funny like 20W), then for 0 to -20 degrees they recommended substituting a quart of kerosene for oil, and finally for temps -20 to -40 degrees they recommended substituting 2 quarts of kerosene for oil. I believe the engine held 5 quarts total, 4 qts in the crankcase and 1 qt in the filter housing. Judging by the amount to metal shavings you found in your lawnmower engine, I don't believe that those Jeep engines lasted very long with a 40% kerosene mixture once temperatures got anywhere close to above freezing temperatures! (p.s. Is there anyway for PF to test Lubrucity of different oil/diesel/kerosene mixtures at -40 degrees, -20 degrees, 0 degrees, etc.for a WWII simulation??)

    Kerosene has better lubrication properties.

    I thought about it chose seafoam as it has some instruction based on something.I'm glad I didn't I spent a small pile of money building that engine

    Hey Project Farm try using power steering fluid/oil as Engine oil. Lets see what happens. Do this test on a small engine because If power steering fluid fails to lubricate the engine which will damage the engine, the damage will be less and would be cheaper to repair than a big car engine.

    I used diesel in an old Chevy suburban to clean up my crankcase. I just cranked it and didn’t allow it to actually start and it worked very well. This was in conjunction with a head gasket repair where antifreeze was in the crankcase. Thank you for your videos! Love them!

    I found that diesel in the crankcase in extreme cases will cause low engine oil pressure under normal operating conditions and cause damage to the main and big end bearings even when it is mixed with good quality oil.

    I have an old chevy 350 with about 130,000 miles. It was my grandfathers so it had sat for a long time and I found a lot of sludge in the pan. It began to tap real loud as if a lifter was stuck. I removed the pan and scraped the sludge out, installed 5 qts. of 5W-30 and a pint of diesel. When I started it, it tapped and then freed up. I ran the diesel/oil mixture for about 6 minutes, drained it filled it with fresh oil and it has never tapped again. Everytime I change the oil, I add 1 pint of off-road diesel to a cold engine, run it for about 5 - 6 minutes, drain it and fill it. This really worked for me. I also do this to my small engines but with of course a lessened diesel amount. Great video thank you.
