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.
Uniform Tire Quality Grading, commonly abbreviated as UTQG, is a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction. The UTQG was created by the National Highway Traffic Safety Administration in 1978, a branch of the United States Department of Transportation (DOT). [ 1 ]
The oil fails the test at a particular temperature if the oil is too viscous. The grade of the oil is that associated with the coldest temperature at which the oil passes the test. For example, if an oil passes at the specified temperatures for 10W and 5W, but fails at the 0W temperature, the oil is grade 5W. It cannot be labeled 0W or 10W.
In both tests, the time taken for 60 ml of the liquid, held at a specific temperature, to flow through a calibrated tube, is measured, using a Saybolt viscometer. [2] The Saybolt universal viscosity test occurs at 100 °F (38 °C), or more recently, 40 °C (104 °F).
CarComplaints.com was featured in a December 2014 Lifehacker article, Five Best Car Comparison Sites, [5] and also mentioned in several New York Times articles from 2013 to 2015: Ford Windstar Minivans Recalled for a Second Time, [6] Chrysler Owners Sound Off on a Power Defect [7] and Ram Dashboards Cracking.
The load index on a passenger-car tire is a two- or three-digit numerical code used to cross-reference a load & inflation table that will give the maximum load each tire can carry at a given pressure. The load index is sometimes used in conjunction with the load range, which appears elsewhere on the tire.
Cold inflation pressure is the inflation pressure of tires as measured before a car is driven and the tires warmed up. Recommended cold inflation pressure is displayed in the owner's manual and on the Tire Information Placard attached to the vehicle door edge , pillar , glovebox door or fuel filler flap .
By this time, Express Oil Change operated 172 company- and franchise-owned locations across 10 states. [6] In 2013, as Express Oil Change had expanded to nearly 200 locations across 13 states, Carousel Capital reacquired the company from Thompson Street. [7] Expresst acquired Birmingham-based Tire Engineers, a company with seven locations. [8]
