All but one of the products supplied by Petrojam will see price increases come tomorrow.

$4.50 cents will be added to the cost of five products.

These are: E10, 87 and 90 gasoline, automotive diesel oil, ultra low sulphur diesel and kerosene.

Propane LPG will go up by $0.25 a litre.

The only reduction is for butane LPG by $0.25 a litre.

Petrojam said as tensions in the Middle East continue, oil prices remain above seasonal averages.

This prompted price increases in transport fuels for another week.

Dealers and marketing companies will add their respective mark-ups to determine retail prices.
