About the range

Engine oil reduces friction and wear between an engine’s moving parts, while managing heat, controlling deposits and protecting against corrosion. Without it, even a well-built engine fails quickly under normal use.

Gem Oils supplies engine oils for every application on Irish roads and yards, from heavy-duty diesel formulations for commercial fleets to passenger car and small-engine products, each manufactured to recognised OEM and industry specifications.

The right oil depends on engine type, fuel and manufacturer requirements, not on what happens to be on the shelf. Our technical team will confirm the correct viscosity grade and approval for your vehicle or equipment, whether you’re ordering for one car or a mixed commercial fleet.

Common Questions

Engine Oils Products FAQs

Answers to the questions we are most commonly asked by garages, fleet operators, and motor factors. For vehicle-specific advice, contact our technical team directly.

Gem Oils supplies engine oils across four categories: Heavy Duty Diesel Oil (HDDO) for commercial fleets, passenger and light commercial oil for cars and vans, garden engine oil for lawnmowers and groundscare equipment, and a general range for off-highway, marine auxiliary and stationary engines. All products are supplied to OEM, API and ACEA specifications across mineral, semi-synthetic and fully synthetic grades.

The correct engine oil is set by the equipment manufacturer and will be listed in your owner’s handbook or on the filler cap. It will specify a viscosity grade (such as 5W-30 or 15W-40) and a performance specification (such as an ACEA or API category). If you are unsure, contact the Gem Oils technical team with your vehicle make, model and engine type and we will confirm the right product before you order.
