Before and After Samples

Microbial contamination in hydrocarbon fuel can be a serious problem for storage tanks and equipment. It can cause serious fuel storage tank corrosion and corrosion in pumps and injectors. It will clog filters, fuel lines and gauges and will cause seals, hoses and connections to swell and blister.

How Much Octane Is Enough?

How Much Octane Is Enough?

Stepen fourth
  • octane
  • performance
  • boost

The rule of thumb is to use the lowest-octane gasoline that will operate the engine efficiently. For the vast majority of modern cars and trucks, that means regular unleaded, which is typically 87 octane. The octane rating of gasoline is a measure of the fuel's resistance to ignition, meaning the higher the octane rating, more heat and pressure are required to "start the fire." If the recommended octane gasoline provides proper starting, power, drivability and efficiency, there's no benefit to using higher-octane fuel.

You'll have to be the judge of whether 89 octane gasoline provides more performance and mileage to offset its higher cost. It could, but in most cases won't.

Biological Contamination

Treatment of fuel storage tanks against biological contamination

Carel mark
  • microbial growth
  • storage tank

The microbial growth is only possible in the presence of water without which they are not able to survive or they enter into a sleeping phase. In general it is sufficient a quantity of water of 100 ppm (part per million) for the multiplication of microorganisms.

The standard fuels contain up to 0.2 ml of water per litre, one-third of this is dissolved in the fuel while the remainder it is collected on the bottom of the diesel tanks.

Therefore microorganisms can live and multiply in diesel fuels particularly in the condensate that collects on the bottom of the tanks or which is finely distributed in the fuel.

The consequence of microbial growth is the formation of sludge in the contaminated tanks that cause the blockage of filters. In addition, metal tanks are corroded by the acid formed by the metabolism of microbial growth
