What is the difference between 95 and 98 petrol?
The main difference between 95 and 98 petrol is the octane rating. 98 petrol has a higher octane rating than 95, making it more resistant to engine knocking and ideal for high-performance or turbocharged engines. 95 is suitable for most everyday cars.
What is E10 petrol?
E10 petrol is regular unleaded fuel that contains up to 10% renewable ethanol. It is designed to reduce CO2 emissions and is suitable for most petrol cars built after 2011.
Is E10 the same as 95 or 98 petrol?
E10 typically refers to 95-octane petrol with up to 10% ethanol. 98-octane fuel is usually sold as E5 (with up to 5% ethanol) and is not as available as E10.
What is AdBlue?
AdBlue is a non-toxic liquid made of urea and deionised water, used in diesel vehicles to reduce harmful nitrogen oxide (NOx) emissions. It is injected into the exhaust system, not mixed with fuel, and is required in many modern diesel vehicles that meet Euro 6 emissions standards.
What is the difference between regular diesel and premium diesel?
Premium diesel has extra additives and a higher cetane number, which means it burns more efficiently and helps keep your engine cleaner. It can lead to smoother performance, especially in newer or high-mileage diesel vehicles.
Is premium petrol like 97 or 99 octane worth it?
Premium petrol with higher octane (97 or 99) is designed for performance or turbocharged engines. If your car doesn't need it, you might not notice much difference, but it won't do any harm either.
What is BP Ultimate or Shell V-Power fuel?
BP Ultimate and Shell V-Power are premium fuels with extra cleaning agents and additives. They're made to improve engine performance, reduce build-up, and may help with smoother driving and lower emissions.
Can I use premium petrol in a car that takes 95 octane?
Yes, you can use premium petrol in a car that runs on 95 octane. It won't damage the engine, and in some cases, it might give slightly better performance or fuel economy, but usually the difference is small.
What is the benefit of Circle K MilesPLUS diesel in Ireland?
MilesPLUS diesel has added detergents to help clean your engine and improve how the fuel burns. It's aimed at drivers who want better fuel efficiency and long-term engine protection.
