The Royal Automobile Association of South Australia has warned that Adelaide motorists are being conditioned to accept higher fuel prices.

RAA technical advisory service manager, Andrew Clark, said retailers have increased their usual profit margin, with prices per litre sitting at 30 cents above the wholesale price, with motorists paying around $1.60 per litre.

Mr Clark said while high points of the fuel cycle are higher, a slow conditioning of motorists to higher fuel prices is becoming apparent as protest from the public appears to be lessening.
