Kerosene as engine oil flush?

If you use it in the crankcase you might risk damaging the seals like the crankshaft seals, which are difficult to replace.

*Bry is this for your taxi fleet? If it is I suggest you avoid doing these things and just undergo routine maintenance such as tune ups, oil changes, fluid changes and their corresponding filter changes or cleaning, to maintain the cars in their optimum shape. Otherwise since it's not the best known method of maintenance just avoid it for peace of mind.

The decision is up to you and you know the risks now. If it works, well then good but if not then that's your call. When in doubt, don't na lang. Just my opinion. Good luck.

Yup I already told my mechanic to not use kerosene any more or any other flushing oils. Just regular routine maintenance from now onwards. Thanks!

kerosene is ok as it is use by mechanics to clean engine parts, removes residue and even washes dirty hands, downside is pag may natira sa loob that's when the problem comes in cgurado halo yan sa new oil mo and 100% sira viscosity ng oil so the oil will not function as i has to be LuBRIcate.

better use quality engine flushes.

info: STP engine flush is kerosene

In my opinion, as long as you change oil according to PMS or shorter (4000klm) everything will be ok. If you think your oil sump is full of debris and contaminants, pulling down the oil pan is the best solution.

oil based engine flush. meaning oil din sya w/ detergents to removes slugde. try opening a can of STP amoy at kulay plang kerosene na kerosene na.

actually, no need para sa engine flush. just drain the oil overnight while the vehicle's tilted.

or if you have the means, used compressed air to flush out the used oil in your engine.

actually pwede naman. pero it has to be a super diluted concentration mixed with engine oil. no way should you use it na puro...

bos speedyfix, just n case, pwede nyo din buksan ang oil pan and tanggalin ang sludge pag nag oil change dyan?

never pa kasi na buksan ang oil pan pero regular ang oil change.
