   He said some work but most do not, and that care must be taken when using these additives because some may contaminate the catalytic converter. Also, if too much is used, the additive may cling to valve stems and cause them to hang open. [5] Most mechanics agree that consistent use of a fuel with adequate cleaning ability is best [citation ...

No. 1 fuel (similar to kerosene) has a natural CFPP of -40 °C but it is more expensive than No. 2 fuel. Adding No. 1 fuel will lower the CFPP of No. 2 fuel – adding 10% will lower the CFPP temperature by about 5 ...

   The cetane number is a key property of diesel fuel, as it measures its aptitude to self-ignite in the combustion chamber. [8] The auto ignition temperature of diesel fuel is around 220 °C (428 °F) at atmospheric pressure. Cetane improver additives are used to decrease this temperature and lead to quicker combustion, by increasing the cetane ...
