The honeycomb makeup of a Diesel filter is lined with precious metals. When combined with extreme heat and the combustion gases, it creates a chemical reaction within the DPF to burn off its contents. The conditions needed for a DPF to regenerate itself are not often met with short city driving. This results in excessive soot build up within the DPF. Taking your vehicle on long road trips, where the engine is running at high speeds for at least an hour, is perfect for enabling a passive DPF regeneration. Another option is having an active DPF regeneration carried out, which is possible through the use of quality OBD2 diagnostic equipment.

Brake fluid should be replaced once it reaches 3.5-4% moisture content, which typically takes approximately 2 years or more. High moisture content can bring your brake fluid boiling point to as low as 125C, where it usually operates at over 300C. The compromised brake fluid creates a very small amount of steam when boiled, causing tiny air pockets throughout the braking system. These are then compressed when the brakes are applied, resulting in a spongey brake pedal feel. The water also degrades the metal components of the hydraulic system. A brake fluid flush flushes out the air pockets and all the contaminants that are built up in the brake fluid system. It also replaces the compromised brake fluid.

If Adblue reaches a critically low level, it can potentially damage the Adblue injection system or the DPF. Every manufacturer has a different procedure for checking or refilling the Adblue additive. So, it is important you check your vehicle service book as to when the Adblue system is due for a refill. Alternatively, you can ask your mechanic. If the Adblue warning light appears on your dash, it is very important to have it checked as soon as possible.

Diesel exhaust gases are higher in unburnt hydrocarbons, which enter the crankcase by means of the piston ring blow by. These exhaust gases mix with the engine oil in the sump, which is detrimental to the longevity of the engine oil. This is because the gas degrades the oil and breaks it down. The viscosity of the oil is compromised, as well as the many additives within the engine oil. They will lose their ability to perform, just as the oil loses its ability to adequately lubricate the engine.

Diesel engines run hotter, harder and dirtier than petrol engines. This means their engine oil needs to have a greater ability for heat dispersion, neutralise the oil, prevent contaminants from creating sludge and additives to prolong DPF life. If petrol engine oil is used in a diesel engine, then the oil will break down very quickly, lose its specified viscosity rating and become quite gritty in texture. Diesel engine oil used in a petrol engine can aid in premature wear on piston rings and engine seals.

Ceramic brake pads wear a lot differently to the standard pads in several ways. Ceramic brake pads are embedded with a combination of high strength ceramic and copper fibres. The ceramic pads leave less brake dust residue, are less susceptible to brake squeal and have increased durability. However, the ceramic brake pads do wear harsher on the brake discs and are more expensive to replace.

Driving your vehicle with a dirty engine air filter essentially puts extra load on your engine where there should not be any. As a result, it can lower fuel efficiency, engine performance, compromise the engine vacuum system, and cause the engine to run quite rough. In the worst-case scenario, dust can enter your intake system and wreak havoc on your engine internals. This can create major and permanent engine damage.

Brand itself does not make a difference QUALITY does!

No, you don’t. As manufacturer endorsements change all the time, it depends who can do the best deal for whom. What is most important is that you are using a high-quality engine oil that suits the necessary specifications for your vehicle. For example, Peugeot endorse Mobil engine oil. However, numerous testing procedures have proved Castrol to be of finer quality.

Engine and underbody trays come standard with most European vehicles. These trays help protect the underbody components during day to day driving. If your vehicle is leaking any sort of fluid such as engine oil or coolant, then it is often caught by the undertrays. Whilst these undertrays certainly serve their purpose, it often means that leaks can go undetected whilst they further deteriorate. This could potentially cause serious issues.
