Ensuring that your car has the right engine oil is an important part of keeping it running smoothly. Benefits of an oil change include:

  • Correct lubrication
  • Cooling
  • Cleaning
  • Internal component protection

There is also the considerable financial benefit gained when doing this at home and cutting the garage out of the equation – should you choose to take your service kit to the garage then it’s good to know that they will be using a top quality oil in your vehicle, rather than the “standard” oil used in garages for servicing – it’s worth it just for the peace of mind.

As part of this, you will also receive an OEM quality filter, as well as the option of choosing a top of the range K&N filter that has been matched using an extensive fitment database, so you can rest assured that you will be fitting only high quality products to your vehicle. Combined with this is a FREE disposable filling kit which includes a funnel, gloves and handy wipes – making your oil change easy and mess free!

To get started, simply follow this link and enter your vehicle details to find the specific kit for your vehicle, it’s really that easy.


Got a race, track or custom vehicle? Not a problem, get in touch with our recommendation form and we’ll match the right products to your specific set up, it’s condition and even your style of driving. Alternatively, give us a call on 01209 202 944 and we’ll be happy to help!

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.

Battery chargers and booster cables – ready to go at Opie Oils

Battery failure – the most common cause of breakdown in winter


blog cable

At Opie Oils, we stock a wide range of battery chargers and testers and booster cables, perfect for keeping your battery in top condition over the winter months.

Due to sudden temperature decreases at this time of year, this can lead to what we like to call the “triple-whammy”

  • Battery power output drops

  • Ability to accept a charge drops, meaning that the battery doesn’t recharge as swiftly whilst you are driving

  • Battery load increases – lights, blowers, wipers, heated seat, rear screen heaters etc are used considerably more

Combine these with the fact that many cars stand unused over the Christmas holiday, it’s no surprise that the first day back to work after New Year is always one of the busiest of the year for breakdowns according to the AA.

However, with the right gear, you can keep your car, bike, truck or even tractor running smoothly throughout the depths of winter – Once your batteries are charged we also sell trickle chargers to keep them topped up, condition testers, performance testers and battery refreshers & conditioners – even solar powered battery chargers for your motor home.


That’s about it from us for now, and remember, drive safe and happy new year!
