This should be an eye opener to diesel engined car owners. The condition and quality of diesel in the Nigerian market is appalling. I have observed that there is so much adulterated diesel in circulation that can ultimately clog up your fuel system with catastrophic consequences to your engine as well as associated emission components. I have worked on diesel engines for over 30 years now and this is the worst condition of sludge and dirt that I have ever found in any diesel fuel tank.

Most diesel fuel bought on the black market and also gas stations could possibly be contaminated with dirt and water that can potentially cause engine malfunctions that could adversely affect your fuel economy. A Toyota Prado diesel was brought into my workshop as a non-starter and further diagnostics revealed what you see in the pictures below.

1. Diesel fuel tanks (Main and reserve) was filled with sludge and water.
2. Diesel filters in the fuel tanks was completely covered in sludge.
3. Engine bay filter was completely blocked with dirt.

A proper wash of the fuel tanks and brand new filters had the vehicle back on its feet and now drives superbly.

Avoid black market diesel and change your filters regularly (every 10,000kms).
Clean out your fuel tanks (every 20,000kms)

This will be the effect of adulterated diesel, the owner of the car should review the diesel purchase channels in order to put an end to future occurrence and also if the driver is allowed to buy the diesel for the Prato ,he might be tempted to buy adulterated diesel in order to make some little cash at the detriment of the engine of the vehicle

Great, 30 yrs is the time to develop local design as an improvement over Toyota stuff. We can't afford to be the mercy of tech for ever, Pls.

This is serious. Everything is fake in Nigeria.

Even the one in Aso rock.....we were managing London used....now they imported moded version

One day i willing pack my bags and baggage, storm your workshop and be the best apprentice you have ever taught in your life time. I need to learn how to repair diesel engines

true talk. walahi, just say no time again, man need money

The best day to do that is today.

If it's what you want talk to the op and start now.

Does Toyota now have a model named Prado? Never heard of it.

Thanks for sharing. Biological growth in the storage tank is also a contributory factor. The fuel may be good and pass all test including water content at the time of supply, but over the years, there is usually accumulated biological growth that contribute to sludge.

dats aw my brother's truck engine was destroyed. wen we checked d tank it was full of kerosine & black oil..may God save us in dis country.

Cardoctor.
I helped you move your thread to the permanent site.
So people can see the quality of diesel we have in this country.

Nice one bro. Lets tell them about it.

make i no just swear......

some bacteria thrive in diesel.
that slime you see at the bottom of contaminated diesel is a mixture of the the organisms and water.
it has been my practise to ask the dispenser put a few milliliters of ago in a transparent water bottle before I purchase in my car. if the diesel is not clear, free of particles or sediments, I pay for what was put in the transparent bottle and say my byes.
I am yet to have issues over diesel quality.
many diesel engine owners knowingly patronise black market sellers cos they are cheaper and turn around to cry wolf when things go wrong.
diesel by its nature absorbs water. this is made worse by temp differences during the night. at night, the moisture in the air in the diesel tanks condenses and drops down to the bottom of the diesel tank. this process repeated over a long time leafs to accumulation of water inside diesel tanks.
that picture from the op is from a car owner who buys black market diesel.
ash and soot from the kpo fire refining process mixes with diesel and add the absence of any treatment, organisms that thrive on diesel have a field day in the tanks of whoever buys such diesel.
last time I cleaned my tank after 40,000km of fuelling, I had a very insignificant slime coating in the tank. not enough to clog a filter.

Old thread I know but that thick stuff in the fuel tank and on the pump assembly was

Petrol vehicles may not be as bad but they have their problems too.

Requested similar work on fuel systems of my vehicles over the years. Just a few months ago, I cleaned out my fuel tank, pump assembly and injectors after hard starting problems and it was something else. Clogged fuel strainer, tar like deposits on injectors, clogged nozzles etc.

The preventive maintenance in this area has always been at my prompting. Mechanic prefers to wait for the car to develop serious problems so that he can then charge me an arm and a leg for repairs.

sometimes depends on vehicle. For a first generation Toyota sienna it's a tough job. You have to bring down the tank from under the car to get to the fuel pump. A DIY would certainly cause neck ache. some other cars is as simple as loosening the back seat and getting to the fuel pump

Its hard to believe but there was a time when petrol sold at filling stations in Nigeria was of different grades - there was 'regular' and 'super'. I recently ran into someone who owned a couple of filling stations way, way back and he said the two tier system disappeared sometime in the early to mid 1980s.

The current arrangement is destroying cars and imposing an unecessary cost burden on consumers. The really tragic part is that Nigerian crude oil is of really good quality with low sulphur content. If we weren't so useless at managing our refineries and other things why should this country import petrol of dubious quality from international oil traders?
