Dirt can form and build up over time on critical engine parts, such as intake valves and fuel injectors. This can contribute to:

  • Sluggish engine performance

  • Increased fuel consumption

  • Less smooth running

  • Critical engine parts needing repair .

A build-up of dirt can create more dirt within the engine – it’s a vicious cycle.

bp Ultimate Unleaded with ACTIVE technology contains millions of dirt-busting molecules, specially designed to clean your petrol engine and protect it from harmful dirt.

BP’s formulation fights dirt in two ways:

  1. Removing existing dirt: ACTIVE molecules attach to dirt and drag it away from critical engine parts. The dirt mixes with the fuel and is then safely burnt in the engine.

  2. Protecting against build-up: ACTIVE molecules also attach to clean metal surfaces inside the engine, forming a protective layer that helps stop dirt from binding to the metal.

With ongoing use, BP Ultimate Unleaded with ACTIVE technology forms a barrier against dirt on critical engine parts, helping prevent its return and keeping your engine performing as the manufacturer intended.

Engine technologies evolve and continue to place increasingly high demands on fuels. At BP, we work to anticipate and understand these changes, developing fuel formulations that complement engine innovations while continuing to benefit older engines.
