The Most Common Wiper blades problem;

Streaking this happens when the rubber dries out, hardens or cracks. This can also be caused by tree sap, road tar and other foreign substances that has gathered on either the windscreen or the blade.

Skipping normally occurs when the blade develops an arc due to lack of use.

Wearing starts when the blade is used extensively as the rubber edges are rounded instead of squared.

Splitting is when the sun’s ray damage the rubber causing it to breakdown and separate from the frame.

Spark Plug Firing End Appearances And What They Mean

Hi Folks,

Ensuring your spark plugs are functioning correctly is an important part of keeping your engine in good health. But how can you tell the difference between a plug that’s doing it’s job, and one that’s on it’s last legs? Well, the appearance of the firing-end of a used spark plug directly reflects the condition of an engine, so Opie Oils and NGK have got together to show you the different appearances of the firing end of a spark plug and how to interpret what this can actually mean.

Normal Condition


If the firing end of the spark plug is brown or light grey, the engine condition can be judged to be good and the spark plug is functioning correctly.






The gathering of different deposits on the firing end is influenced by oil leakage, fuel quality and engine operating period. The deposits can come from Carbon, Lead, Bromine, Calcium, Sulphur, Barium and Zinc.




Dry and Wet Fouling


Dry and Wet Fouling is another way the firing end can be damaged. If the insulation resistance between the centre electrode and the “shell” is over 10M ohms the engine can start up normally, however if the insulation resistance drops to 0 the firing end is fouled by either wet or dry carbon.



Lead Fouling  

Leadfouling If your spark plug firing end looks yellowish brown on the insulator nose, this is found on spark plugs that have been damaged by lead. Also, this particular type of damage cannot be detected by a resistance tester at room temperature.  Lead compounds combines at different temperatures; those formed at 370-420 degrees Celsius have the biggest influence on the resistance.







If your spark plug has overheated, the insulator tip is glazed or glossy. Deposits which have gathered on the insulator tip have melted, and there is a chance that the insulator will have blistered.






Breakage is normally caused by a thermal shock due to sudden heating or cooling – replace immediately!





Normal Life


A worn spark Plug not only wastes fuel but also strains the whole ignition, this is because is requires a higher voltage. A worn spark plug can reduce the engine efficiency by reducing the fuel economy and increases the exhaust emissions. For your reference, The normal rate of gap growth is about 0.01 0.02mm/1,000 Km for four stroke engines and about 0.02 0.04mm/1,000 Km for two stroke engines.




Erosion, Corrosion, Oxidation


The electrodes have oxidized, and when the oxidation is heavy there will be green on the surface.  The surfaces of the electrodes are also fretted and rough.





Abnormal Erosion


An Abnormal Erosion is caused by corrosion, oxidation,  or reaction with the lead. This results in abnormal gap Growth.





Lead Erosion


Lead Erosion is caused by the lead compounds in the gasoline which react chemically with the material of the electrodes (nickel alloy) at high temperatures. Crystals of nickel alloy fall off because of the lead compounds permeating and separating the grain boundary of the nickel alloy. Typical lead erosion causes the surface of the electrode to become thinner and the tip of the electrode looks like it has been chipped.






If the firing end is melted, this means it has over heated. Mostly, this will result in the electrode surface being rather lustrous and uneven. FYI, the melting point of nickel alloy is 1,200 – 1,300 degrees Celsius.




If you’re wondering how often should you change your spark plugs, Opie Oils are sorry to say there is no single simple answer to this question.  The best guide is the manufacturer’s recommendation for your vehicle, as this particular service varies from manufacturer to manufacturer and brand to brand.
