Once, I personally had to visit many petrol pumps to source used engine oil (hardly 10 liters) so as to not delay the construction.

Yes, you are right. Construction field is the bigger consumer of the used oil in urban areas.

Please don't forget Marine industry. Ships burn these spent oil when they are on international waters. I got to know about this from a bulk buyer in Chennai who was waiting in a car dealership to take the spent oil barrel. They make quick buck selling these to large Marine tanker vessels.

As indicated by others construction workers are the next big buyers & oil / metallurgy companies come next. They need these oils as cheap fuel for their industrial scale production & as alternate fuel.

I have rarely come across someone who recycles. One chemical company salesman told me that it takes a lot to purify the spent oil & output usually forms the base for next. But recent developments in synthetics & good quality fuel is helping them in recycling process.

I want to better understand the draining process, and I have a couple of queries:

1. How long does it take to drain out the oil from a bike?
2. After draining out the oil, you turn on the engine and warm it, to remove the remainder? or you warm the engine and then drain the oil?
3, What does FNG stand for?

Depends on the motorcycle and also oil. Normally around 30 mins. Even after this some oil would still remain in the case.

You can't remove all of the old oil. When you warm the engine , due to movement of parts , you will drain out further oil.

Thanks srini for the prompt reply!

To add my procedure -

Usually the engine oil will flow out within 5 minutes, after which it will only trickle.

You need to warm up the engine BEFORE draining the oil and NOT AFTER. Once the oil is drained out, I don't even prefer kicking it over - each turn of the piston will result in some fuel getting sucked in and remain un-burnt, something I am not comfortable with. The way-out (though not fool proof) is to unscrew the spark-plug and then kick it over a couple of times - you'll be able to see a thin stream of oil flowing out. Better way is to tilt the vehicle on its centre stand a couple of times - and repeat this process three to four times. This method will take at least 30 minutes.

My bike is quite old - 13 years almost (Yamaha Gladiator). The oil sump is closed and it has only an oil screen for filtering purpose.

Newer bikes that I know of - Yamaha FZ, in this case - have an oil filter for filtering the oil, which can be accessed without opening the engine / oil sump, and replaced. I am not sure how one goes about oil change on such bikes - probably they remove the filter before draining the oil?

As I have a manufacturing unit, I always bring the used engine oil in my factory. So at the time of maintenance I use them for oiling purpose in bearings,gears, chain sprocket and even in bushes.

The serve the purpose which i Intend to during maintenance period.

[ringoism]

I always give mine to any random service station, most of them get rs12-15/L for spent oil, there are industries set up using recycled oil, no point re-inventing the wheel, it is a resource, it has a value, and as such not too difficult to find takers! Can't speak to the situation in the metros, but I doubt it would be much different.

I dont know about re-cycling it, but a very useful side of used oil is to use it like a paint on iron pieces to prevent rusting. We have iron spike fences around the property and we use the used oil to coat these fences. I have seen it holding it well for atleast an year. Else for the Kerala rains, the fence will rust in no time. Once we had to "buy" the used oil from a workshop, next time my dad asked them to transfer the oil into the containers and return. The guys still didnt give all the oil back - should be a revenue generation item for them. I also know from my BIL who is in charge of a service centre abroad, has a regular practice of selling the used oil - not sure to whom or for what purposes.

A word of caution since we are discussing used engine oils. Body contact with used oil must be avoided as it is very toxic and contains cancer causing chemicals that unused oils don't. Not only for humans but used engine oils are very toxic for plants and animals too.

This link provides details about used engine oils and its link to cancer:-

https://www.p65warnings.ca.gov/fact-...sed-engine-oil

Used oil is surely toxic and harmful to the environment too, owing to the toxic chemicals it has as ingredients.These contaminants include lead, cadmium, chromium, arsenic, dioxins, benzene and polycyclic aromatics beside micro particles of iron/steel and aluminium. If used motor oil and the contaminants it contains are disposed of inappropriately and released into the environment, they can harm humans, plants and animals. However they do not contain any acids whatsoever as some believe it does and used oil is not corrosive.

From the US Environmental Protection Agency (EPA) link :-

https://www.epa.gov/recycle/managing...cling-used-oil

If you one of the many people who change their own motor oil, you too need to know how to properly manage the used oil. After all, used oil from one oil change can contaminate one million gallons of fresh water — a years’ supply for 50 people! When handling used oil, be sure to take these key points into consideration:

Used motor oil is insoluble, persistent, and can contain toxic chemicals and heavy metals.
It’s slow to degrade.
It sticks to everything from beach sand to bird feathers.
It’s a major source of oil contamination of waterways and can result in pollution of drinking water sources.
Are you a “Do-It Yourselfer” —do you change the oil in your car at home? On average, about four million people reuse motor oil as a lubricant for other equipment or take it to a recycling facility. If you plan to recycle your used oil, take care not to spill any when you collect it and place it in a leak-proof can or container.

Check with local automobile maintenance facilities, waste collectors, and government waste officials to see when and where you can drop off your used oil for recycling. Don’t forget to drain and recycle used oil filters as well—usually you can drop off the filters at the same collection centers where you deposit used oil.

The EPA goes further to say that an appropriate way to overcome the problem of handling used engine oils is to recycle them using the proper procedures. The EPA also says that recycled used motor oil re-refined, performs as well as virgin oil and in some cases even outperforms the latter.

Recycling and reusing used motor oil is preferable to disposal and can provide great environmental benefits. Recycled used motor oil can be re-refined into new oil, processed into fuel oils, and used as raw materials for the petroleum industry.

So, how is used oil recycled? Note that the most preferred option, re-refined oil—must meet the same stringent refining, compounding, and performance standards as virgin oil for use in automotive, heavy-duty diesel, and other internal combustion engines, and hydraulic fluids and gear oils. Extensive laboratory testing and field studies conclude that re-refined oil is equivalent to virgin oil—it passes all prescribed tests and, in some situations, even outperforms virgin oil.

The same consumers and businesses that use regular oil also can use re-refined oil, since re-refining simply re-processes used oil into new, high-quality lubricating oil. Any vehicle maintenance facilities, automobile owners, and other machinery maintenance operations that use oil also can use re-refined oil. In some cases, fleet maintenance facilities that use large volumes of oil arrange to reuse the same oil that they send to be re-refined—a true closed recycling loop.

An EPA poster:-



Used engine oil can also cause impairment of male reproductive parameters based on research as this link below says.

Conclusion

Hence, it can be said that there is a negative relation between used engine oil and male reproductive parameters. And it can be concluded that used engine oil should be prevented from leaking, spilling or improperly discarded as through medium it may enter storm water runoff and eventually affect the environmental health receiving water bodies.

Hi All, does anybody know of a trusted enterprise in bangalore where I can go drop off used engine oil?

Oil is gold, drop it at your nearest garage and it will find its way to a recycler or next consumer.

[Indian2003]

I used to burn used engine oil in the wood stove. I place a caste iron pot with about 2 liters of oil in the stove and fire up with wood.
After some the wood is all burnt up and the oil fire goes on like a jet engine.
The flame is purple in colour
