Dear Mr Preston,
Thank you for your email dated 9th June 2009. I have done some further
research regarding the use of waste lubricant oil in a diesel engined
road vehicle, and I would value some further advice.

Thank you for your advice on this point. Most of the issues regarding
this are resolved by the fact that I intend on using oil that I
personally remove from engines, processed on the same site, and
immediately transferred to the fuel tank of the road vehicle. I
understand that there are licensing requirements imposed by
legislation, but I will be in correspondence with the relevant
authorities with regard to this.

Having reviewed all the legislation I can find on this point, it is
irrelevant, as I am neither buying waste oil to use as a motor fuel,
nor selling any oil as a motor fuel. None of the legislation I have
found prohibits actual use, only the buying and selling of
"unsuitable" oils with intent to use as motor fuel. You may also be
interested to know that in the UK a high percentage of most cheep
lubricant oil is recycled used oil which has had the impurities
removed and then been re-blended. In the USA, where due to the absence
of fuel duty, rules are more straightforward, at least one firm
markets equipment aimed at vehicle workshops, which is intended to
filter and process waste oil into a road fuel for diesel lorries.
>Additionally, from an HMRC perspective the Hydrocarbon Oil (Marking) Regulations
>2002 prohibit the sale of ‘dark oil’ as fuel for a heavy oil vehicle and lubricating oil
>might well fall within the dark oil specification (at Section 2(1) of the Regulations)
Again, this point isn't relevant provided no financial transaction
takes place to obtain the oil. If the oil in question is drained from
machinery I own then by subsequent use of the oil afterwards as motor
fuel isn't an issue provided it is confined to my personal use in my

Having confirmed the answers to the above questions, I would now be
interested in knowing the appropriate rate of duty, and mechanism for
