Burning your Oil (instead of changing)

[Crazy Dazz]

Gotta love how the experts like to proclaim "it's the LAW", as though Moses is gonna come down from the Mountain and Smite Thee.
I'm not sure what rules different states have, but certainly nobody in WA gives a rats ****.
We're talking about the controlled consumption of maybe 1 part per thousand.
So provided your car still complies with the relevant ADRs, and isn't demonstrably dirty, there would be no problem.
We're actually far stricter on Underground mines, all vehicles have to be routinely tested. But these were open pit haul trucks.
As a general rule, we insist on compliance to Australian Standards, but I'm not even sure what standard exist for these engines. Even on the mid-sized trucks, the engines are around 70L. The big ones are over 100.

I have heard of one such trucking company that got caught dumping their waste oil into their diesel tank. And burning it off that way. Highly illegal.

old valiants i had were that sort of oil burner. so long as you kept them topped up, they'd keep going and going...

I'd be really interested to know what law they were found guilty of breaking? Only thing I can think of is perhaps a law related to the disposal of hazardous waste.

They burn oil in Formula 1 as a power additive.

But they are not allowed to
https://www.insidesport.com.au/news/...burning-466160

The FIA has signalled it will redouble its efforts to stop Formula 1 teams potentially attempting to gain an engine power increase by deliberately burning oil in the combustion procedure.
The oil-burn controversy came to light earlier in the year when Red Bull Racing said it suspected its rivals had found a way around the regulations surrounding the internal combustion component of the hybrid power unit.

In response, the FIA took a closer look at oil usage and consumption, and the chemical composition of the oils being used.

The FIA has now confirmed that the use of chemicals in oil that could help improve combustion is not permitted.

Head of the F1 technical department, Marcin Budkowski, wrote to the teams to re-emphasise the FIA’s position that the use of oil as fuel is prohibited.

"For the avoidance of doubt,” Budkowski wrote, “the only fuel that may be used for combustion is petrol, and the only permitted characteristics of that petrol are clearly set out in Article 19 of the technical regulations.

"Even though the technical regulations do not directly specify the permitted characteristics of engine oil used in F1, we would consider any attempt to use additional components or substances in oil for the purpose of enhancing combustion as a breach of the technical regulations."

Regulation changes planned for next year will require teams to supply the FIA with a measurement of the level of its mail oil tank at all times, will ban active control valves between the power unit and engine air intake, and limit teams to a single specification of oil per engine at a grand prix.

How it works here https://www.matfoundrygroup.com/News...urn_Engine_Oil

One method understood is the addition of second set of injectors at the bottom of the cylinders - below the pistons and just above the crank shaft – which sprays a mist of oil onto the underside of the pistons.

When timed correctly on the down stroke, the increasing pressure in the crankcase will force the oil vapour through the oil ring grooves. Usually these grooves are positioned under the oil ring so they can fulfil their job of collecting the excess oil gathered by the oil ring and channel it back down into the crankcase. However if you modify the number and shape of these channels, and reposition them higher up in the ring seat, you can turn the oil ring into a valve of sorts and control the flow rate of oil allowing it to enter the chamber.

All of this works together to achieve a noticeable increase in performance by circumventing fuel limits and additive restrictions - hence the debate on whether it was within the rules or not.

For you average car this isn’t necessary at all. You don’t have a fuel limit or a restriction on what additives can be added to your tank and so circumventing these isn’t needed, and neither is burning oil. If your engine starts smoking excessively from oil making its way into the combustion chamber and being it burnt, it's still very likely you have a problem that needs fixing.

Using oil in the combustion process in these fuel flow-limited and highly knock-sensitive engines liberates extra horsepower. Oil is less combustible than petrol, but if used for combustion off-throttle, it allows a leaner, more combustible, petrol/air mixture to be used on-throttle when it matters. It effectively allows you more bang for your fuel flow-limited limit buck.

Rotary engines also burnt oil to keep their apex seals lubricated.

e.g. http://www.rx8help.com/before_you_buy/burning_oil.html

and https://nationalspeedinc.com/advanta...rotary-engine/

the Rotary uses oil squirters that take small metered amounts of oil and mix it into the fuel to lubricate the seals

....and of course as those apex seals wear out they burn even more oil.

I can only assume it would be because of their emissions.

I still don't understand why you would do it other than avoid the cost of waste disposal of the old oil.

perhaps the Trucking company was actually dumping it, their excuse was its recycled into the trucks..

what a lot of K#@king around to save a few bucks and potentially destroy your engine.
Might as well pour in some used Fish n chip oil too

More on "black diesel" here http://www.dieseltechmag.com/2014/09/oil-as-fuel and http://www.oiltofuel.com/

I know a several what I would call eccentric farmers in the WA wheat-belt were doing this in the later 80's early 90's and claimed the fuel cost savings (getting the used oil free from neighbours etc) more than made up for any reduced engine life. But many of their neighbors also had the view that they might be slowly killing themselves from the blue cloud of noxious exhaust gas that they were emitting from their tractors and wouldn't even donate their used oil for fear of complicity. It would be interesting to know if indeed their rate of terminal cancers was higher. The view I came to was if the used oil had been refined to some homogeneous standard and the diesels engines and their fuel and emission systems had been designed to use such oil it might have been practical. But it was home brew stuff on engines designed for cleaner diesel. It's probably akin to ship's bunkering oil http://www.vancouversun.com/technolo...350/story.html

I do, It's cleaner than diesel when its filtered right.
