It's no secret petrol in the Southern Highlands is expensive compared to other regions.
However will the re-branding of two service stations make a difference to prices?
The twin 7-Eleven service stations on the Hume Highway at Pheasants Nest officially closed on Wednesday, July 1.
The stores are due to re-open as Caltex/Ampol petrol stations on Sunday, August 2.
It is understood 7-Eleven's lease had ended and Caltex/Ampol signed a lease for the sites.
NRMA media advisor Bridget Ahern said a price drop wasn't likely.
"In terms of prices, we're not expecting them to change considerably when [Caltex/Ampol] take over," Ms Ahern said.
"Because it's a twin service station, there's not much competition with prices."
What will cause a price drop?
The high price of petrol has long been cause for complaint in the Southern Highlands.
Ms Ahern said only an increase in independent petrol stations would fix the problem.
"Unfortunately Bowral and Mittagong doesn't have a huge amount of independents," she said.
"The second there are more independents, prices go down and it makes everyone happier."
Location, location, location
The Southern Highlands once dominated the state's top five most expensive petrol.
Ms Ahern said it has almost fallen in the line with other locations across the state, however it still remained "slightly more expensive".
Large price differences for petrol remain in the Southern Highlands.
The dearest price for diesel at 3.45pm on Thursday, July 2 was 125.9 cents per litre.
This petrol was found at Coles Express in Bowral and Mittagong.
Meanwhile the independent service station in Elm Street, Colo Vale offered the cheapest price at 117.9 cents per litre.
The highest price for premium unleaded was 134.9 cents per litre at Coles Express in Bowral and Mittagong.
The lowest price was found BP Mittagong for 131.9 cents per litre.
Ms Ahern said regional motorists could save up to 10 cents a litre if they shopped around.
"Fuel stations have to legally post prices in real time," she said.
"It makes the petrol stations a lot more accountable."
Ms Ahern said petrol came from the same place, whether it was sold at "Metro petrol stations, tiny mum and dad shops or the big players".
Hence some people paid more for the same product.
"It is the same product. There might be fancy branding or ways of talking about it, but it comes from the same refineries," she said.
