With rising fuel prices, Petrojam is advising motorists in Kingston, Jamaica, to choose the correct octane grade to save money. According to a May 1, 2026, press release, using 87-octane gas instead of 90-octane could save drivers up to $15 per litre. Elon Parkinson, communications manager for Petrojam, explained that most gasoline vehicles are designed for 87-octane, and using 90-octane offers no benefit in such cases. He added that the right octane provides smoother operation, better performance, and engine safety. Petrojam emphasizes that the octane rating measures a fuel’s performance and anti-knock properties. They urge drivers to check their vehicle owner’s manual for the recommended octane grade. Parkinson noted that higher octane does not improve mileage and is only needed for higher compression or turbocharged engines. He recommends 87-octane for optimal performance and reliability in most vehicles. Motorists are encouraged to consult a qualified technician if unsure.
