Cleaning valves on a direct injection (DI) engine requires special attention due to the design limitations of DI systems, where fuel is directly injected into the combustion chamber, bypassing the intake valves. This means traditional fuel additives won’t clean the valves as they do in port injection engines. Over time, carbon deposits can accumulate on the valves, leading to decreased performance and efficiency. One effective method for cleaning valves in a DI engine is walnut blasting. This involves using pressurized air to blast walnut shell granules at the valves, effectively removing carbon deposits without damaging the valve material. It’s an environmentally friendly and highly effective technique but requires special equipment and should preferably be performed by a professional. Alternatively, chemical cleaners designed for DI engines can be used. These are introduced directly into the intake system and require following the product instructions carefully to avoid d...

Ideally. engine oils can typically be stored for a period of five years. depending on factors like composition. container material. and storage environment. Synthetic oils tend to have a longer lifespan compared to conventional oils. To ensure proper storage. the oil should remain in its original. unopened container and kept in a cool. dry location away from direct sunlight or drastic temperature changes. Air exposure or contaminants can expedite decomposition. Before using. it is advised to check for any changes in consistency or color regardless of how it was stored. Consulting the manufacturer’s guidelines can offer specific storage instructions and aid in preserving the quality and efficacy of the oil.
