ON week three of the Glasgow Times giving you the cheapest petrol and diesel prices in the city, Costco still can't be beaten.

Using fuel comparison website PetrolPrices.com, the Cobden Road fuel station is offering petrol at 156.7p per litre and diesel at 170.9p per litre.

For petrol, the supermarkets are still winning.

Next is Morrisons at Newlands for 157.7p, sticking at the same price as last week.

Asda again takes the next slot with its pumps at Robroyston, Govan, Toryglen and Parkhead all offering petrol at 158.7p per litre.

Morrisons at Anniesland is 1p per litre more expensive than at Newlands.

Tesco at St Rollox then comes in at 158.9p followed by Tesco Silverburn 1p a litre dearer at 159.9p.

Asda's four branches are the cheapest for diesel after Costco at 171.7p.

Tesco Silverburn is only slightly behind at 171.9p per litre for diesel and the same price at Tesco St Rollox.

Sainsburys at Woodlands is 174.9p per litre.

And the BP garage and Esso garage on Paisley Road West match that price if the Southside is more convenient for you.
