3000 X1 Formula FE 5W-30, 1L

If you’re looking for a high-performance synthetic motor oil that truly delivers on both protection and efficiency, the Mobil Super 3000 X1 Formula FE 5W-30 stands out as one of the best choices in its class. After running this oil through several fill cycles in different driving conditions — city commuting, motorway cruising, and spirited drives — I’ve been consistently impressed with what it offers.From the moment it goes in, the oil flows beautifully even in cold weather. The 5W-30 viscosity means starts are smooth and stress on the engine is minimized, especially during colder mornings. Once warmed up, it maintains stable protection across all engine components, reducing wear and keeping things running cleanly. I’ve noticed a real improvement in how the engine feels — it’s noticeably smoother and quieter compared to conventional oils I’ve used in the past.One of the strongest aspects of this oil is its balance between performance and fuel economy. It’s formulated to help improve efficiency, and in my experience, there was a subtle but measurable difference in consumption over several tank cycles. That’s exactly what you want from a “Formula FE” oil: lower friction, better flow, and a real contribution to lowering running costs without sacrificing protection.Heat resistance and stability under stress is another area where this oil excels. On longer journeys or hot weather driving, engine temperatures stayed well controlled and there was no sign of oil breakdown or loss of performance. The peace of mind knowing that the oil can handle both everyday use and more demanding conditions is a big confidence booster.Another point worth highlighting is the long drain interval. If you’re used to changing oil every few thousand miles, this synthetic holds up much better over extended use (following the manufacturer’s guidelines, of course). That means fewer oil changes, lower maintenance costs over time, and overall a more convenient ownership experience.Whether you’re driving a modern petrol or diesel engine that calls for a 5W-30 spec, this oil covers all the bases: excellent cold start performance, reliable all-weather protection, reduced engine wear, and noticeable fuel economy benefits. It’s the kind of product that doesn’t just tick boxes on paper — you can feel the difference in real-world use.In short, the Mobil Super 3000 X1 Formula FE 5W-30 is a top-tier synthetic engine oil that’s worth the investment. It keeps your engine running smoothly, protects under a wide range of conditions, and contributes to better efficiency. For anyone serious about engine health and longevity, this oil should be on your shortlist.

Was recommended this oil by other MX5 owners, I’ve gone through 3 bottles in a year and a half as my mx5 is a thirsty (and old) boy but the engine is healthy and runs perfectly!

Yes, I know the title is a bit obvious but look at it this way - spend a few pounds on this to top up your engine between oil changes and you won't risk a major failure.As long as the viscosity is correct (check the owners handbook or just do a search) then all is well.For the sake of two minutes online, you'd be daft not to.
