A,
The treatment you had previously been advised to use would be correct, if you bought and sold diesel as your trade. The specific treatment requiring you to recognise a profit - and therefore to pay additional tax and NI - is in respect of your normal stock in trade. So if you're a butcher and you appropriate some of the meat yourself, you're supposed to 'sell' it to yourself, recognising the full market rate. But if you were to appropriate some stationery, then that would just be a disallowable cost, similar to the diesel already discussed above.
See HM Revenue & Customs' Business Income Manual @ http://www.hmrc.gov.uk/manuals/bimmanual/bim33630.htm
There are different rules for services, rather than goods.
And don't forget VAT - if you're VAT-registered, then you need to consider adjusting your VAT account, either by disallowing some of your input VAT, or using the 'fuel scale charge'. See Andrew Needham's article in TaxationWeb - http://www.taxationweb.co.uk/tax-articles/vat-excise-duties/claiming-back-vat-on-motoring-expenses.html
Kind regards,
