engine flash using diesel

[homework]

sir mam meron po ba gumagamit nang diesel sa pag engine flash i mean pag change oil po pano po ba ito ginagawa
tia

[trucker111]

i saw one mechanic put diesel in coke 1 liter bottle that serve as tank for gun spray (compressor). gaya ng ginagamit ng mga pintor. after draining the oil, spray the engine with diesel, ma flash na yung oil.

[raycon_24]

pag gas powered ang engine mo mas ok gumamit ka na lang ng diesel oil for a week or two then change oil ulit, mataas kasi ang detergent ng diesel oil, ganyan ginawa ko on both of my cars after ko mabili 2nd hand, effective for me kasi wala kang makikitang sludge sa rocker arms assembly after ko mag palit ng VC gasket...

[homework]

sir diesel engine po pag gagamitan ko pano po ba sabi kasi ng iba sakin drain ng 1liter tapos add ng 1liter na diesel paandarin tapos drain tama po ba

Re. using diesel fuel as an engine flush, I remember lowslowbenz explaining this before... have to dig it out though.

If you change oil regularly though, there is no need to flush.

Unfortunately, if your engine already has sludge, the only way to remove it completely is to manually clean it by opening up the engine aka ovehaul. Other than that you run the risk of clogging the internal oil paths in the engine by the sudden release of all that gunk.

If you’re not willing to do that then may I suggest the procedure which I used in my vehicle with some alterations. Get a good oil with good detergency. In my case, I used Top 1 SDO and Mag 1 All Fleet. Then shorten the interval of change oil to 1,000 then 2,500. After that I used a good and tested engine cleaning oil additive. I used seafoam. But I heard that Autorx is also good. Then change oil 1,000 and 2,500 and 5,000 intervals. After completing it, make sure to have your oil pan and oil strainer (if your car is equipped with one) cleaned. You can also add 2t to your fuel to clean your injectors and fuel lines.

thanks sir... negative pala gamitin ang diesel as engine oil Mitsubishi adventure po ang ride ko and pang biyahe po simula po kasi noong father ko gumamit di pa na change oil (30K) na po na tatakbo 2 times na napalitan ng oil filter and nag dadag lag siya ng enkendel oil 2 bottles... and pertua now me na po gumagamit kaya balak ko sana malinisan ng husto bago ko salangan ng SYNTHETIC OlL Top 1 yong red... and thanks po ulit sa info about 2t user narin po me.....

thanks po ulit

no need to use Pertua additive anymore. ok naman ang Top1 SDO. tried and tested na dito sa tsikot.

I use diesel fuel to flush old oil and sludge out (if there are any). I buy a gallon of diesel, drain the old oil, and load in the diesel. Do not remove the old oil filter just yet. Determine that the diesel inside your engine has reached (at least) the minimum level on your oil dipstick. Then let it idle for around 15 mins or so, para umikot ang diesel sa oil galleries, DO NOT REV!

Drain overnight, and remove your old oil filter. Kinabukasan, pour in fresh oil, and screw in a new filter.

Disclaimer: This is what I do, as part of good maintenance habits. You may, or you may not opt to do this procedure, for whatever reason.

sir pano mo po ito ginagawa hinahalo mo po ba ito sa engine oil sample 1 litter then andar idle for 15min tapos drain tama po ba

[lowslowbenz]

No, drain the old oil first, BUT do not remove the old filter yet.

[homework]

drain ko lahat tapos 5 liters of diesel ilalagay ko paandarin ng 2min... walang magiging problem sir?????

a week or two?

[johncoder]

ganyan din ginawa ko kay lowslowbenz pero yung sludge talaga sa valves parang aspalto na ewan ko lang sa oil pan kung ano itsura wala pa akong torque wrench set para buksan 13t engine

This is just the way to free the sludge and gunk in there. But for me, I'll use a high detergent diesel engine oil constantly for short OCIs, say 3,000 kms, 3 to 4 times, until I'm satisfied that my engine is gunk free. Alam naman natin na sludge does not develop in so short a time, so it also takes time to dissolve it.

I change oil DIY only. Drain the oil in a clean pan while it is still warm so it flows easily. Leave it dripping for an hour or two, I come back just when the oil filter is already cold to be removed by hand, install a new filter, tightening it by hand only, the drain plug by a wrench siempre. Wipe all the mess, put the old oil in a jug with tight cap for proper disposal, pour the new oil, start the engine, let it run for 10 minutes, turn off, check for leaks and also the oil level. That's it! Wala na kung ano-ano pa flushing, waste of money. Besides, you can not clean thoroughly what you can not see!

Subukan ninyo mag lagay ng goma sa diesel at tingnan ninyo kung di matunaw yung goma. Yan ang delikado. Kapag gumamit ka ng diesel, lalambot na yung mga rubber oil seals sa makina, crankshaft oil seal, camshaft oil seal, etc. At siyempre kapag lumambot na yan, malamang mag-lileak na rin. Mas malaking trabaho, kasi ibababa mo yung head o yung makina mo para lang palitan yang mga oil seal. Syempre aasa ka na rin na sana hindi nakapasok yung mga dumi dyan na may mga abrasives na nakaka damage sa mga bearings, shafts, etc. Kaya mas mainam kung palitan mo yung oil regularly. Kahit anong kotse pa yan, gas o diesel, ang sikreto sa pag tagal ng makina ay nasa pag palit ng langis regularly. Kung 5k o 10k, depende sa gamit, sa load, sa trapiko, kondisyon ng paligiran, etc. Pero flush with regular oil.

Kung may sludge na lang siguro ko susubukan yung diesel pero baka too late na rin kasi kapag may sludge, usually, marami na ring bara. Di matatanggal lahat ng sludge kahit i-flush ng diesel. Kailangan buksan pa rin ang makina para siguradong walang mga bara katulad ng strainer, mga cylinder jacket.

This actually makes sense. Diesel is not advisable to use as flushing agent as it deforms, softens & bulges rubber seals. As long as you change our oil regularly, flushing is not needed. Sludge forms usually in engines that do not undergo regular oil change intervals

i don't use engine flush. what for?

Well, as long as the change oil regimen is done as specified (i.e. every 5,000kms), there is no need to use an engine flush really.
