Can Fuel Additives and Three-Way Catalytic Converter Cleaners Be Used Simultaneously?

Fuel additives and three-way catalytic converter cleaners should not be used together. Additional information: The functions of automotive fuel additives are as follows: The cleaning and activating factors in fuel additives can remove harmful substances such as gum deposits in fuel and engine carbon buildup. After five consecutive uses of fuel additives, carbon deposits on the exhaust pipe are significantly reduced, including in the filter, exhaust valve, and fuel system. The nano-components in fuel additives encapsulate gum deposits, creating gaseous "micro-explosions" in the combustion chamber under high temperatures, which promote secondary atomization of fuel and ensure complete combustion, thereby enhancing engine power. Over 90% of vehicles experience a noticeable improvement in power after the first use of fuel additives.

What does glass oil film mean?

Oil film refers to a layer of grease and impurities adhered to the car window glass. There are several causes of automotive glass oil film formation: First, vehicle exhaust - exhaust emissions contain various pollutants from incomplete combustion. Frequent traffic congestion in urban areas, especially when driving behind trucks, inevitably leads to these substances adhering to the glass and forming an oil film. Second, oil smoke pollution - if frequently parked near restaurant chimneys, accumulated grease and dirt will gradually form thick oil stains if left untreated. Additionally, insect remains and bird droppings, which are highly corrosive, can harden on the glass if not cleaned, affecting transparency and potentially developing into oil films. Lastly, tree resin - vehicles regularly parked under trees may accumulate sap and fruit residues.

What Causes High Temperature in Motorcycle Liquid-Cooled Engines?

Motorcycle liquid-cooled engine overheating is primarily caused by poor heat dissipation, with specific reasons including: insufficient coolant and cooling system malfunctions. Insufficient Coolant: Lack of coolant or using inappropriate coolant prevents timely heat dissipation from engine components, resulting in excessively high water temperature. Cooling System Malfunctions: Obstructions in the radiator grille mesh or core ventilation ducts by debris lead to inadequate heat dissipation. Cooling fan failures prevent efficient heat transfer to the antifreeze during high-speed operation, causing the antifreeze temperature to rise and potentially leading to boiling issues.

Why was the Nissan GT-R discontinued?

Here are the reasons why the Nissan GT-R was discontinued: 1. Reason one: The implementation of the China VI emission standards means the current GT-R models no longer meet China's emission requirements. 2.
