Soo koob maqaalka:  Shirkadaha shidaalka iibiya ayaa ka xaday dadweynaha iyo ganacsiyada qiimaha shidaalka, sida laga soo xigtay RAC. Qiimaha jumlada ee shidaalka naaftada ah waa 1p halkii litir oo ka badan tan batroolka, weli shidaalka naaftada ah waa ku dhowaad 6p in ka badan mashiinnada, ayay tiri. Waxaa jira fursad hoos loogu dhigo qiimaha shidaalka ee qiyaastii 4p halkii litir si loo soo celiyo isku dheelitirnaan suuqa, RAC ayaa intaas ku dartay. Shirkadda baabuurta ayaa u yeertay dukaamada, iyadoo sheegtay in ganacsiyada ay si gaar ah u bixinayaan khidmadaha xad-dhaafka ah ee Diesel maadaama iibka shidaalka uu kordhay. Ra'yiga RAC ayaa yimid markii ay soo bandhigeen tirakoobka Dowladda oo muujinaya in wadarta iibka shidaalka ay kor u kacday 3.5% bishii Febraayo marka la barbar dhigo isla bishii sanadkii hore. Iibinta gaaska Diesel bishii la soo dhaafay, 2.42 bilyan oo litir, waxay ka dhigan tahay tiradii shanaad ee ugu badneyd bishii tan iyo 1990. Laakiin iibka batroolka ayaa ka mid ah kuwa ugu hooseeya 25 sano. Ganacsiyada, kuwaas oo u badan tahay in ay ku shaqeeyaan Diesel ayaa la jabsaday by tafaariiqleyaasha kuwaas oo raadinaya si ay uga hortagaan khasaaraha ka soo qiimaha shidaalka hooseeyo. Shirkadaha sida caadiga ah ku shaqeeya shidaalka naaftada ah, waxay si gaar ah ugu daran yihiin burburka shidaalka. Afhayeenka RAC, Simon Williams, ayaa yiri: "Waa adag tahay in aan la rumaysan in ganacsiga la qaatay. "Iyada oo iibka shidaalku uu aad u sarreeyo, tafaariiqleyda ayaa sii waday inay sii wadaan sicir-dhimista shidaalka, laga yaabee inay taageeraan iibka batroolka".
RAC waxay sheegtay in shakhsiyaadka iyo ganacsigu ay si aan caddaalad ahayn u bixiyaan qiimaha shidaalka. Dowladda ayaa muujineysa in iibka shidaalka uu kor u kacay 3.5% bishii Febraayo marka la barbardhigo sanadkii hore. Iibka shidaalka ayaa aad u sareeya halka iibka batroolka uu yahay mid aad u hooseeya 25 sano. Shirkadaha, ee sida badan ku shaqeeya shidaalka naaftada ah, ayaa si aad ah u saameeya burburka shidaalka. Qiimaha shidaalka waa in hoos loo dhigaa 4p si loo sameeyo suuqa cadaalad ah RAC ayaa leh.
