Here’s where things get a little confusing. In the late ’90s and early 2000s, there were just two grades: JASO MA and JASO MB. If friction-testing results in all three areas fell within the JASO MA parameters shown in the table, the oil received a JASO MA classification and you wer...
If we put all of the above together,we have at one end of the spectrum sweet light crude oil, the holy grail so to speak, and at the other end heavy sour crude oil with some medium grades somwehere there in the middle. Sweet light crude oil has a lower liquid density to water and...
We must not lose sight of the enormous burden put on the environment by the excessive emissions of CO2 in order to produce the 150 mill tonnes of low sulphur fuel, we estimate to be demanded annually by 2010, through the distillation of residual fuels, when the SECA areas are extended to...
Mid-grade fuel lies somewhere in between the other two grades, typically with an octane level of 89. The Federal Trade Commission says if your engine in pinging with regular gas, then upgrading to mid-grade may stop it. Only a handful of cars require or recommend mid-grade. “On engines ...
There are only six children on the island in winter, so they all attend a one-room schoolhouse, where grades one through eight are taught by one teacher. The most common method of transportation is the mail ferry. It comes to the island everyday in the summer but in the winter it only...
In addition to the low temperature viscosity grade, there are high temperature viscosity grades SAE20, 30, 40, 50, 60, and the greater the number, the higher the viscosity of the oil. Usually when the weather is hot, use a high viscosity engine oil, but in cold weather application of ...
Octane rating is an important measurement regarding gasoline. It indicates the resistance to igniting too early. Higher the octane rating, the higher the quality of gasoline. There are several octane rating grades. In early times, manufacturers used lead (leaded gasoline) to increase the octane rat...
