Hi ! I have some hard questions want to ask you.
*what term describes oxygen containing fuels which, when blended with petrol, raise the octane number
*State the main reasons why motorists cannot simply choose to change and or intermix the various fuels available for their motor cars from the selection of pumps on the forecourt of a typical petrol station.
*On January 1, 2000, the use of LRPs and AWAs was introduced into the lives of many car owners in this country.
=> What is LRPs and AWAs ? And why this did not affect all car owners.

Please help me !
Thanks.

Many of your questions involve jargon used in the fuel industry, and some of them use idioms, that I don't use in my flavor of English.   There was probably some reading material assigned with these questions, and you should probably look there for answers first.
