Hi, I own Volkswagen Virtus. Previously, I strictly used XP95 to meet the car's 95 RON requirement. However, with the introduction of E20 fuel, standard petrol now has a 95 RON rating, meaning the only distinction in XP95 now is its additive package. Are the these additives really helpful for TSI engines and is it worth spending extra money for XP95? Could you rank the top 3 petrol for VW TSI engines?
You’ve got it right, and our own testing backs you up. When we lab-tested fuels last year, regular E20 petrol measured 98.2 RON and XP95 98.8, almost no difference. XP95 is also an E20 blend, so the two are now much the same fuel.
Are the additives worth it? Only marginally. Premium fuels carry extra detergents, but the ethanol in all E20 petrol is already a strong solvent that helps keep deposits down. Your TSI is also a direct-injection engine. The fuel goes straight into the cylinders and never passes over the intake valves, so no fuel additive can keep those clean. Regular servicing, the correct oil and the odd long highway run matter far more. Filling XP95 occasionally won’t hurt, but you don’t need it every time.
Ranking the top three petrols. We haven’t tested fuel brands against each other, so we can’t fairly rank them, and the gap between them is small anyway. Pick a busy pump from a major oil company, where the fuel is fresh and the tanks are well kept, and stick with it.
