In the order of things C 99 Ethanol, a product of vegetable origin, which is mixed 100% with E85 and its petrol. Risks and disadvantages of E85 Highly corrosive for cleaning pipes and tanks. Attacks metal, due to the electrolytic torque associated with the mixture of condensation water and ethanol. Consumption + 20 to 25%. Loss of power and torque Increased engine wear due to oil dilution (oil changes every 10,000 km). Choose between installing a kit costing between 1,000 and 1,200 euros or driving on 75% E85 and 25% petrol. Increase in the selling price of E85 in 2021 Advantageous purchase price of 62 cents per litre. Less polluting vehicle. Why use C 99 ethanol It can be used with the kit or with 75% E85 and 25% E5. Consumption close to that of a petrol engine, the purchase of the Kit is not essential as the calculators manage the advance point and injection times up to 75% E85 and 25% petrol. It increases the efficiency of ethanol engines, improves combustion and ignition. Ethanol C 99 protects* the engine and hoses, homogenises the petrol/ethanol mixture and reduces the detergent effect of ethanol. *C 99 ethanol allows a very good distribution of the electrolytic torque and protects against preferential attacks linked to the presence of water in the ethanol. It facilitates cold and hot starts. Why use P 18 with an ethanol engine? Ethanol is very detergent, it will dilute the oil film on your cylinders, the engine will be less well lubricated, which will lead to frequent oil changes as the ethanol sinks into the engine oil. Vehicles using ethanol need even more oil changes than with P 18. Once every 5 refuellings with ethanol, use 10 litres of petrol with 50 ml of P 18 for an anti-wear shock treatment of the injectors and injection pump. P 18 Anti-wear treatment: Higher compression, even more essential with E 85.
