With over 100 years of experience in the fuel industry, we believe there is no question or problem that Portland cannot answer or help you solve. We want to hear your questions and issues with regards fuel buying, fuel quality, fuel consumption, petrol forecourts, grades of fuel, refining etc, etc, etc. The list really is endless and we would like you the fuel user to test us so we can help you!

Feel free to send us a question. We will publish it on this page along with the best answer we can give. Please indicate if you wish to remain anonymous and we will publish the question without your name.

April 12, 2016 Regarding your comments on BSOG (Bus Service Operators Grant) and the rebate currently paid by the Government. The amount should actually be a lot higher, had the Government not decided to break the linkage between fuel duty increases and the fuel duty rebate. So for all the years that we saw Fuel Duty increases in the 2000’s, this was not reflected in increases to the BSOG rate. Plus don’t forget that buses do not compete with hauliers, but they do compete with other public transport modes who pay less or no duty.

OK George…keep your kilt on! But you’re absolutely right on this one – the BSOG rebate / duty rise correlation was removed long ago and according to the original intent of BSOG, the rebate should have continued to rise in line with increases to fuel duty throughout the 2000’s. Not least because one of BSOG’s original intentions was to protect “lifeline” public bus services and not penalise those services with higher fuel duty rates.

Equally pertinent is your second point on fuel duty (or lack of) for other modes of public transport. Airlines pay no fuel duty at all and trains – probably the most direct competitor to buses – only pay 11.14ppl. That’s not even half of what the bus industry currently pays and that certainly seems pretty unfair to us.

This comment comes from our good friend George Mair (Scotland Director at the Confederation of Passenger Transport), following our latest Oil Market Report (March 2016).

February 24, 2016 What is the percentage of bitumen in road asphalt?

Woah Sandy! That’s a very specific question. But the answer is circa 5%-10%, depending on how much level of water-proofing is required against rainfall. As your question comes to us from the West Coast of Scotland, we can only imagine that the level is around 10% where you live…!

This short and sweet question came from Sandy in Gourock

December 22, 2015 You said in your November report that the green movement is not entirely supportive of Carbon Capture & Storage (CCS). Why is this?

That’s a really interesting question Stephen because it’s true to say that there is no real consensus view on the benefits of CCS.

On the one hand, some environmentalists are enthused by the potential of CCS and believe it is a natural bridge to curb emissions. It is also technology they say, that can immediately make an impact in the reduction of emissions, rather than some of the alternatives around renewable energy – which most agree are still 10-20 years away in terms of mass implementation.

However, there is another viewpoint on CCS espoused by the likes Greenpeace. They have called CCS technology a “dangerous distraction in the fight against climate change” and simply see the large-scale projects around CCS as a route for big oil and big energy to avoid reducing emissions – after all, if carbon capture becomes so effective, what incentive will there be to actually reduce fossil fuel consumption? Portland can see that this point of view has a certain element of logic. If we could use the analogy of dealing with an alcoholic, the real cure for the affliction would be to stop drinking (ie, curb emissions) rather than providing more and more headache tablets (capturing emissions) to deal with the hangover the following day.

On balance though, Portland sees CCS as one credible way of moving the world to a lower carbon energy future and in a relatively civilised way – with much less social and financial upheaval, that some of the more radical switches to renewable energy would entail.

As a final point, there are still many out there who say that CCS cannot work from a technical perspective and that it is therefore, a complete waste of money. Interestingly this viewpoint actually comes from both sides of the climate change divide, with both climate change deniers and the likes of Greenpeace claiming that the technology simply doesn’t exist to deliver reliable CCS programmes. Both these parties have an interest in denigrating CCS technology (for different reasons), but that being said, as we sit here at the end of 2015 there are still no large-scale, fully functioning CCS projects in place anywhere in the world. And until that changes, such views will continue to be held.

We had this question from Stephen in glorious Oban, Scotland

I think your comments about Euro VI trucks in your recent Oil Market Report are incorrect. NOx as such is not an aggressive greenhouse gas and in general Euro VI trucks are only a minor improvement over Euro V for fuel consumption (3-4%). So I would not expect much positive impact on global warming from this change – the main purpose of which is to improve air quality.

OK Mike. Banged to rights. We got that wrong and the researcher in question has been thrown from the ramparts of Portland Towers. What I think we can say correctly though, is that modern commercial engines (trucks, buses) are unrecognisable to their counter-parts of 20 years ago. Plus, whilst Euro VI engines may only be a 3-4% improvement in terms of fuel consumption, Euro V engines were in turn, a similar improvement over Euro IV engines, which were an improvement over Euro III engines and so on. All of this has meant that emissions of some greenhouse gases have been reduced tenfold over the last 20 years.

We had this question from Mike at Energetics Europe Ltd ( – a man who clearly knows more about emissions from Euro VI engines than we do.

May 7, 2015 Liked your last market report on gas. Can you elaborate a bit more on the burning efficiency of gas versus other fossil fuels?

(Here is a link to April’s Oil Market Report) Not sure we can really elaborate too much on the technical side Ben. As the report says, we are oil men really rather than gas experts. But fundamentally, gas has less carbon content that either oil or coal because the hydro-carbon chains are lighter (basically, more hydrogen molecules for every molecule of carbon). So in a nutshell, more energy and less carbon is produced when gas is burned than is the case with other fossil fuels which generate more wastage (carbon, soot) and less energy (in proportion to the volume used).

Gas has other advantages too – particularly over coal – when it comes to power generation. Firstly gas power stations are generally cheaper to run and maintain (again because the product is cleaner) and the process of reducing output on a gas powered station is fairly straight-forward. This is in stark comparison with coal-fired power stations, which basically need to stay running 24/7 / 365 days of the year – partly because of long-term heat generation requirements, but also because the capital costs in both building and maintaining coal-fired power stations. This tends to make gas a perfect partner / back-up for alternative energies such as solar and wind power. During periods of wind / solar energy peaks, gas power stations can go into idling mode but can immediately kick in when the wind doesn’t blow or the sun doesn’t shine.

We received this question from Ben in Lichfield.

Is James Spencer's fat face on the website as fat as that in real life?

Sadly the answer to this is yes Patrick. As you well know, because you are my brother.

We got this probing question from Patrick in Hertford in April 2015.
