Vehicle Longevity – Fuel Treatments

Passenger car driving on the road

Making your current vehicle last longer and aiding engine longevity will be at the forefront of many motorist minds. It is also something we have been thinking a lot about at Millers Oils, and more importantly about how we can help you do this.

Here is our short guide on vehicle longevity – just putting in a few small practices into your routine can help prolong your engine life and make for a smoother running vehicle, saving you larger costs on repair bills or a new vehicle.


How fresh is your engine oil? Engine oil is formulated to last the duration of a service interval in either time or miles – whichever comes first. However, there are benefits to doing more frequent oil changes. Cleaner oil has better lubrication properties and therefore better at friction reduction, making the engine run smoother. It can also improve your vehicle’s fuel economy.

If you are thinking of changing your engine oil but are unsure of the oil your vehicle needs check your handbook, and then find out which Millers Oils product best suits your application by using our Which Oil guide: www.millersoils.co.uk/which-oil – or by contacting our Technical Help Desk on +44 (0)1484 475060.

Before an engine oil change, we recommend you use an engine flush for the best results. View our Engine Flush product page.

When considering a vehicle service please remember that it should be done at mileage or time period but this can differ from the car and manufacturer, for example, every 12 months or 10,000 miles – but whichever comes first. If you have only done 7,000 miles but 12 months have passed, you should still book in for a service. These guidelines are in place for the longevity of your vehicle.

Fuel system

Injectors have the vital job of dispensing fuel into the engine efficiently.
Components like injectors in the fuel system can become dirty over time, one way this happens is hardened lacquering on the injector spray holes. The lacquering can then affect the spray pattern of the injectors meaning fuel is not dispersed properly. This then affects engine performance, resulting in poor efficiency and fuel economy.

To help prevent this you need to incorporate a treatment into your routine that contains detergency. For initial clean up, especially if you suspect you have lacquering, use either the Millers Oils Petrol or Diesel Injector Cleaner Treatment. View our Petrol Injector Cleaner or Diesel Injector Cleaner product page.

For continued protection, use diesel or petrol ECOMAX each time you top up with fuel to maintain system cleanliness. View our Petrol Power ECOMAX or Diesel Power ECOMAX  product page.


Has your vehicle been parked up for longer than usual?
Did you know when the fuel is left in the tank the volatile components, octane for petrol, cetane for diesel will start to reduce off. To help with this you can add a fuel treatment to the tank during the lay up or just before you want to start using it again. We recommend incorporating our Millers Oils Petrol or Diesel Power Ecomax.

Have you got a diesel vehicle doing reduced mileage?
Cars fitted with a DPF that recently have only been doing short distance trips may end up with build up or a blocked DPF system. To replace this or to do a manual clean-up is very expensive, however, it is a vital component in a diesel vehicle and can’t be left blocked.

Our Millers Oils Diesel Particulate Filter Cleaner and Regenerator will force the filter to regenerate and burn off excess soot. View our Diesel Particulate Cleaner and Regenerator product page.
