Save on engine oil expense

[jarre]

Dear Hyper milers
I came across an interesting device on the net that claims to recylcle engine oil and one can drive three times longer on the same oil.The device is called an oil cleaning centrifuge and there are many companies selling from small to big machines.
Has anybody tried this device? imagine the benefits for people with many cars,u can suggest this idea to your company if they have many vehicles.If this device really works imagine the savings from foriegn oil imports
Please let me know if u have tried this device.
Moreover we can save on oil filter changes too and be eco friendly at the same time,according to what I have read some new diesels have on board centrifuges and that it is mandatory in some countries for big diesels to have this device on board.

The problem with old oil isn't just contaminants floating in it; various chemical additives get depleted over time. So a thorough cleaning process by itself is not enough for returing used oil to service.

jarre,
The idea works well enough to separate the physical impurities but the chemical degradation to the oil remains.

When I was working for a mining company we had a fleet of Caterpillar diesel trucks and stationary generators. It was remote location and it snowed in the Winter.
We used the oil from the trucks in the heaters after centrifugal filtering.

It works but there is a lot of energy required to filter the oil (we used a four stage filter process) and the product is nowhere near the quality of new oil.
We had Mobil test it for us and they said it is OK for a boiler or space heater (ours were Lamborghini) but that was about all.

What about putting good oil in your good car, then using the waste oil from it into your beater?

I used to do that all the time.

Better yet, use that fuel to heat your business. One of the fascinating things about used oil is that it has the same amount of energy content as it did before it was used, which makes it a great—and cheap!—fuel. Businesses that generate this oil can safely recycle it onsite in the most environmentally friendly manner available with a waste oil furnace or boiler. These complete heating systems provide safe fuel management, EPA-approved used oil disposal and free heat. Emissions are incredibly low and the byproduct is a fine ash that can be thrown away. As if eliminating a heating bill weren’t enough!
All waste oil furnaces are not the same. EnergyLogic systems are the only complete systems that make fuel management, maintenance and ownership simple. They are engineered for extensive use in rugged climates, which means they can withstand any shop environment. They require no daily, weekly or monthly manual adjustments so working them is as simple as setting the thermostat.

There was an article in the local Country Lines (magazine sent out by the electric company) about a guy who burns waste oil for heat. He said something about the ash being very alkaline and works really well in his garden.

Guys thanx for the insight,the reason I asked this info is because in ethiopia used engine oil is usually chucked in the sewer which ends up in the eco system
Only fuel stations with oil changing bays sell their used oil for furnace users,as for heating we dont use them here cause it is a tropical country.
If I tried to cry about this nobody would give a f*** about the ecology and would just laugh at me or look oddly at me.Most of my friends already think that Iam a bit loco with my ideas about hyper miling etc.
The idea is if there is an economic reason to recycle oil well there will be less pollution,and what do you guys think if we use the recycled oil blended with diesel as a source of fuel for old trucks and buses[there are many old italian trucks and buses here which are very tough]will a little used oil hurt the injector nozzles?

I actually had scrounged enough parts to build a waste oil heater at one point. (Based on the drip pan designs I found on the net) but there was no way the city was going to allow it since I planned to have it on my detached garage and not part of the house. (Go figure)

I even checked into having its own chimney installed, but they still werent budging. Oh well.

Jarre: I think long term effects are damaging, but short term I know truckers did it a lot when fuel prices rose here.

Sounds like jarre has a wide open market for collecting waste oil. There's your moneymaker!

Does this mean bypass oil filtration won't allow extend oil change intervals?
