Shell Helix Diesel Ultra
Fully synthetic motor oil that helps clean and protect for Shell’s maximum performance.
- Better engine protection
Shell Helix Diesel Ultra continually prevents soot deposits from building-up on engine surfaces.
- Longer protection thanks to enhanced oxidisation resistance
Up to 30% more protection than other fully synthetic leading brands tested.
Actively cleans for Shell’s maximum performance
Shell Helix Diesel Ultra motor oil delivers Shell’s ultimate cleaning technology, which helps diesel engines to operate efficiently for maximum performance and protection. Soot from diesel combustion can increase an oil’s viscosity and force the engine to work harder. Shell Helix Diesel Ultra is designed to remove soot from the engine surfaces without a large change in its viscosity.
The oil actively cleans the engine and continues to flow quickly, so that the engine operates efficiently and maintains performance and fuel economy. The oil in a clean engine then has improved access to surfaces, so that the engine is better protected.
The outstanding cleansing power and shear and oxidation stability of Shell Helix Diesel Ultra mean that it goes on delivering its benefits throughout the oil-change interval.
Shell Helix Diesel Ultra is specifically formulated for turbocharged and intercooled, direct-injection, high-performance diesel engines that are fitted with blow-by-gas and exhaust-gas recirculation. It meets vehicle manufacturers’ extended and severe service specifications.
Shell Helix tests
To clean and protect an engine, the oil must continue to perform until it is removed when the car is serviced. With some manufacturers recommending longer service intervals, an oil’s ability to stay fit is even more important. Throughout the oil’s life, it has to disperse more and more dirt – keeping it locked away and preventing it from being redeposited in the engine.
Our scientists perform a variety of tests that measure the ability of Shell Helix oils to resist breakdown and disperse dirt. We also test our competitors’ oils, so that we can benchmark our lubricants and demonstrate the benefits of using Shell Helix oils.
Proven to keep your engine cleaner for longer
Soot and sludge can build up in diesel engines, and reduce engine performance and prevent the oil from protecting the engine components. Tests in an independent laboratory showed that Shell Helix Diesel Ultra oil can remove soot deposits from a diesel engine. The engine was run with a mineral motor oil for a typical oil-change interval and sludge built up.
The oil was then replaced with Shell Helix Diesel Ultra, and the engine was run again for a similar period. An immediate clean-up effect was seen with Shell Helix Diesel Ultra, and, although it contained soot from the previous oil, the Shell Helix Diesel Ultra went on cleaning the engine for the entire test interval.
Shell’s maximum engine performance and protection
It is critical that oil rapidly delivers protection to where it is needed, particularly when the engine is cold and most vulnerable to wear. Shell Helix Diesel Ultra oil provides Shell’s maximum performance and protection, based on ACEA and OEM specifications, and it flows faster at engine start-up (5°C) and operating temperatures (85°C) than other oils*.
*10W-40 oil in Europe and 20W-50 oil outside Europe.
Why you should use Shell Helix Diesel Ultra:
- Provides the best engine protection by continuously preventing soot deposits.
- Up to 30% more protection than other fully synthetic leading brands tested.
- Flows up to 4.5 times faster than a 20W-50 oil at start-up temperature.
- Greater fuel efficiency and easier cold starting.
- Maintains viscosity and stays in grade throughout the oil-change interval.
- Reduces oil volatility and therefore oil consumption and the need for top-up.
- Smoother, quieter drive.

Shell Helix Oil is the only motor oil Scuderia Ferrari recommends. That’s why Shell Helix is inside not just every Ferrari Gran Turismo car that leaves Maranello, but also every Ferrari Formula One car at every race.
Specifications and approvals
Because lubricants vary in quality, universal criteria are used to describe oil performance and usage. Shell Helix motor oils not only meet these increasingly demanding international specifications but usually surpass them. Shell Helix Diesel Ultra exceeds these specifications: API CF; ACEA B3/B4; BMW LL-01; MB approval 229.5; VW 505 00; Renault RN0700, RN0710; FIAT 9.55535 Z2 (meets requirements).
