Lubricants are always optimized to meet the requirements of international classifications (API, ACEA). However, there are many ways of formulating a specific type of lubricant. Mixing two oils that have equivalent properties will not pose a problem, but final performance cannot be guaranteed. All market oils (petrol engine or diesel, mineral or synthetic) are mixable. However, a blending of two oil qualities lower the superior quality.

No, because motorcycle four-stroke engines do not operate under the same conditions as those of cars (higher engine rpm and temperature). The engine lubricant can also be used to lubricate the gearbox and the clutch, which requires a formula with EXTREME-PRESSURE ADDITIVES. On the other hand, passenger vehicle lubricants contain DETERGENT ADDITIVES with a high ash content. In motorcycle engines, these cause deposits to form on the valve train and the piston crowns, which can result in valve burning or piston perforation.
The answer to this question depends on the technology used. Although some older vehicles allow the same lubricant to be used for both the engine and the gearbox, new vehicles require different products for each. Follow the manufacturer's recommendations.
Around the period of the transfer, we will send a meter reading agent to take an opening reading from your meter. This means that your account will be accurate from the moment you transfer to us.
We will also send this reading to your previous supplier so that they can close your account with the same reading.
This meter reading can be taken from five days before to five days after the transfer.
We always advise our customers to take their own meter readings too, just in case the agent isn’t able to access your meter during this time. You can email this reading to us at [email protected] or call us on 0333 003 7874.
Please take a meter reading from your business electricity meter as close to the date of your transfer as you can. The reading can be taken from five days before to five days after the transfer.
Please email the reading to us at [email protected] or call us on 0333 003 7874.
Once the contract is in place, we will contact your previous supplier to let them know of your intention to leave. Please ensure that you have terminated your contract with your supplier or there may be some delays in transferring your energy supply.
During normal vehicle operation, oil is vital to ensures leak tightness between the combustion chamber and the crankcase. The oil pressure indicator shows how well this is being done.
An unusual drop in oil pressure can result from either lower engine oil viscosity due to dilution by fuel (injector problem or use at low load) ; too little oil in the lubrication system (due to an oil leak, excess oil consumption, or failure of the oil circulation pump) ; or even mechanical part wear.
The engine oil level should be checked regularly to prevent incidents. A small amount of the oil that circulates in the engine is always burnt (an engine in good condition consumes between 0.2 and 0.5 liters of oil every 1,000 kilometers), but successive top-ups are no substitute for an oil change.
Accordingly, it is natural that an engine consumes a small amount of oil, which can be offset by top-ups between oil changes; however, excessive need for top-ups can be an indication of mechanical problems (leaks, etc).
Petrol and diesel engines have different lubrication requirements. During development, lubricants undergo a number of tests, some common to diesel and petrol engines and others specific to one or the other type, that categorize their performances. At the end of this process, they are awarded an API or ACEA/CCMC compliance standard. These specifications characterize the acceptable functioning of the lubricant in each type of petrol or diesel engine. Lubricants for four-stroke engines usually comply with both petrol and diesel specifications. For example, an API SJ/CF lubricant meets petrol specification SJ and diesel specification CF. But this does not necessarily mean that it will perform in the same way in both petrol and diesel engines. This is why Elf has developed specialized ranges, optimized either for petrol or for diesel.
