Both Rotella T4 15W-40 conventional and, Rotella T6 5W-40 and 15w-40 Synthetic both list the JASO MA/MA 2 standard; this information can be found on the bottle adjacent to the SAE/API rating stamp. JASO is an acronym that stands for Japanese Automotive Standards Organization. Note that the 10W-30 conventional oil does not list JASO-MA.
for a given application, [12] but the cold-cranking simulator (CCS, see ASTM D5293-08) and mini-rotary viscometer (MRV, see ASTM D3829-02(2007), ASTM D4684-08) are today the properties required in motor oil specs and define the Society of Automotive Engineers (SAE) classifications. Oil is largely composed of hydrocarbons which can burn if ignited.
Grades may appear alone - for example, a lawnmower may require SAE 30. This single grade specification means that the oil must meet the SAE 30 requirements. But SAE also allows designating an oil with two viscosity grades, referred to as a multi-grade oil. For example, 10W-30 designates a common multi-grade oil. A 10W-30 oil must pass the SAE ...
Unlike earlier diesel engines the B-series Cummins used direct injection and did not need glow plugs for cold starting. [2] The engine was first manufactured in Rocky Mount, North Carolina, and other plants were later added in Mexico, Brazil, Turkey, and Darlington, UK. [3] It uses a gear-drive camshaft for extra reliability. Also specified is ...
The VI scale was set up by the Society of Automotive Engineers (SAE). The temperatures chosen arbitrarily for reference are 100 and 210 °F (38 and 99 °C). The scale was originally interpolated between 0 for a naphthenic Texas Gulf crude and 100 for a paraffinic Pennsylvania crude. Since the inception of the scale, better oils have also been ...
The royal kids might not be allowed to keep some of their Christmas presents from the public this year thanks to the family's strict rules about gift giving.
Diesel engines are used in aircraft, automobiles, power generation, diesel–electric locomotives, and both surface ships and submarines. The Diesel cycle is assumed to have constant pressure during the initial part of the combustion phase (to in the diagram, below). This is an idealized mathematical model: real physical diesels do have an ...
(The Center Square) – A new Republican oversight report accuses former Congresswoman Liz Cheney of colluding with witnesses in the Jan. 6 Select Committee investigation that she oversaw.
