Sulfated ash

There's a second good reason you shouldn't use car oil in your motorbike - sulfated ash. It's common in many American & Canadian modern oils; without burnt oil discoloring it, it normally has a light-gray to pale-tan colouration which may become visible if you shear a bit of the debris. When coloured by oil, it looks like the dreaded sludge. Unfortunately, the API SH-SN ratings are not strict enough on sulfated ash content. It's an issue that's fairly well known in some motorcycling circles, and the Japanese motorcycle industry recognized the issue very early on, creating a new oil specification specific to their needs (one, that among other things, caps the sulfated ash content very low): JASO-MA, recently revised further into to JASO-MA1 & JASO-MA2. For motorcyclists, the sulfated ash content poses a secondary issue: it means higher quantities of sulfuric acid if water gets introduced into the oil (such as from condensation within the galley spaces); since most motorcycle engines share the oil with both the engine and the transmission, the sulfuric acid is particularly problematic as the metals used in the transmission selector forks are made of cheaper steels that don't stand up to the acid nearly as well as most engine components.

Can I use diesel engine oil in my petrol engine?

This is an awkward question to answer. Diesel engines run much higher compression ratios than petrol engines and they run a lot hotter, so the oil is formulated to deal with this. Plus they produce a lot more dirt in terms of combustion by-products. Diesel-rated oils typically have more detergents in them to deal with this (see Using Diesel oil for flushing above). It's not unheard of for diesel oils to clean a petrol engine so well that it loses compression. Diesel-rated oils also have an anti-foaming agent in them which is unique to diesel engines, and not needed in petrol engines.
So is that the be-all and end-all answer? Well not really and that's why this is a difficult question to give a straight answer to. The above statement is more relevant to commercial diesel engines. Nowadays, just about all passenger car / light commercial oils (including OEM ones designed for both petrol and diesel engines) will carry the ACEA A and B specifications. ie. formulated to satisfy the requirements for both types of engine. So just because the oil is labelled "Diesel" doesn't mean it's not suitable for petrol engines - it will more than likely carry an ACEA A3 / OEM petrol spec as well.
However you do need to be a bit careful regarding choosing the right diesel spec - if you have a modern common rail / direct injection diesel, chances are it will require at least an ACEA B4 spec to cope with the higher piston temperatures that can cause piston deposits (and stuck rings). ACEA B4 is fine where B3 is recommended.

Notes to ponder

Soot Could Slow Down Global Warming

NASA claims that the government could slow down worldwide global warming by cutting down on soot emissions. Studies by NASA show that cutting down on soot would not only have an immediate cooling effect, but would also put a stop to many of the deaths caused by air pollution. When soot is formed, it typically travels through the air absorbing and releasing solar radiation which in turn begins to warm the atmosphere. Cutting soot emissions would be an immediate help against global warming, as the soot would quickly fall out of the atmosphere and begin to cool it down.

Cutting back on soot emissions would buy us time in our fight against global warming. Soot is caused by the partial burning of fossil fuels, wood and vegetation. Soot is known to contain over forty different cancer causing chemicals, and a complete cut would offer untold health benefits worldwide.


What's The Biggest Contributor To Climate Changes?

Environmental conservation has always been a topic for lengthy discussions, but up until recent times, global warming and climate changes were vague subjects, with no hard proof. Not surprisingly, the previous lack of attention to these issues have created a very gloomy outlook on our future. So, considering all this, what could be the biggest contributor to climate changes through global warming? Transportation - the man-made iron horses, flying machines and sea monsters, so to speak.

The question we have now is how green is our transportation? The majority of the worlds' vehicles are fueled by oil (petrol, diesel and kerosene). Even if they rely on electricity, the stations used to generate this electricity use fossil fuels for power! Excluding vehicle manufacture, transportation is responsible for 14% of the artificially created greenhouse emissions, mostly carbondioxide.

Automobiles, trains and planes are all responsible for this problem, but cars are the highest impact-makers. They release approximately six times more carbondioxide than a plane and seven times more than sea vessels.

What is Air Pollution?

Air pollution is somewhat difficult to define because many air pollutants, at low concentrations, are essential nutrients for the sustainable development of ecosystems. So, air pollution could be defined as:A state of the atmosphere, which leads to the exposure of human beings and/or ecosystems to such high levels or loads of specific compounds or mixtures thereof, that damage is caused. With very few exceptions, all compounds that are considered air pollutants have both natural as well as human-made origins.

Air pollution is not a new phenomenon; in Medieval times, the burning of coal was forbidden in London while Parliament was in session. Air pollution problems have dramatically increased in intensity as well as scale due to the increase in emissions since the Industrial Revolution.
