Antonija  +  457902 Fri, 28 Dec 07 05:20 PM Is it better to say "petrol content", "petrol composition" or "composition of petrol"? Thank you Antonija Joined on Sun, Mar 5 2006 Croatia Contributing Member 1,248

	Mister Micawber  +  458096 Sat, 29 Dec 07 07:58 AM I like 'the composition of petrol', but I would like to see it in context. Mister Micawber

	Antonija  +  458382 Sun, 30 Dec 07 06:52 AM It has to do with blending of petrol. It is blended with different components, than it has to be a composition. Thank you Antonija

	Mister Micawber  +  458392 Sun, 30 Dec 07 08:10 AM Well now, I've finally done a little internet research.  Yes, composition: "In a nutshell, gasoline is a mixture of C4 to C12 hydrocarbons specially blended with a few additives to meet the performance needs of automobile engines. That doesn't sound too complicated, but in actuality gasoline is quite complex, consisting of several hundred compounds. The composition of gasoline can vary widely depending on the blending specifications required for different regions based on climate and environmental regulations." Mister Micawber
