Millers Oils Diesel Injector Cleaner - 400ml

It is generally recommended to use one 400ml bottle every 10,000 miles as part of routine maintenance to keep the injection system clean and performing optimally.

No, this specific product is formulated exclusively for diesel engines. Using it in a petrol engine can cause damage.

While it's best to add to a half or full tank for optimal mixing, adding to a low-fuel tank will still allow the product to mix as you refuel and drive. However, performance benefits might be slightly less immediate compared to using it in a fuller tank.

This cleaner is designed to address issues caused by fuel injector deposits. It will not resolve mechanical failures, sensor issues, or problems unrelated to the fuel system.

While generally safe, it's best to use this product as directed and avoid mixing with other complex fuel additives simultaneously, as their combined effects are not always predictable. Stick to one primary additive at a time.

Many users report noticeable improvements in engine performance, acceleration, and smoothness within a single tank of fuel after application.

Ensure the entire bottle was used and the fuel tank was sufficiently full for proper mixing. Very severe injector blockage might require multiple applications or professional cleaning. Check for other potential mechanical issues unrelated to the fuel system.

This cleaner addresses fuel system deposits. If a warning light persists, it may indicate a different issue with the engine or emissions system that requires professional diagnosis.

Clean up spills immediately with absorbent material. Avoid contact with skin and eyes. If contact occurs, rinse thoroughly with water. Ensure the area is well-ventilated.
