Domestic diesel fuel is classified by pour point, with light diesel having six grades: 5, 0, -10, -20, -35, -50, and heavy diesel having three grades: 10, 20, 30. The relevant introduction to diesel is as follows: Introduction to diesel: Diesel is a light petroleum product, a complex mixture of hydrocarbons (carbon atoms number about 10-22). It is used as fuel for diesel engines. It is mainly blended from diesel fractions produced through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. Uses of diesel: The most important use of diesel is for diesel engines in vehicles and ships. Compared to gasoline, diesel has a higher energy density and lower fuel consumption rate, but exhaust emissions contain more harmful components (NO, particulate matter, etc.).

Should I Replace Both Rear Tires If One Is Damaged?

It depends on the situation. If both tires have been driven for a considerable mileage and the wear exceeds at least 5mm, then a pair should be replaced. If it's a new car or has only been driven a few thousand kilometers, you can replace just the damaged one. The general principle is to ensure that the two tires maintain consistency in brand, specifications, tread pattern, structure, etc. Below is relevant information about car tire replacement: Replacement duration varies by situation: For drivers with good driving habits, tires generally need to be replaced every 3-5 years or after driving 60,000-80,000 kilometers. In harsher road conditions, such as frequent driving on gravel roads, frequent traffic jams, sudden braking, or sharp turns, the replacement interval will be shorter. Tire aging time: The main material of tires is rubber, which undergoes natural aging, primarily manifested as hardening of the tire and small cracks on the sidewalls. The natural aging period is typically 4-5 years. Tires should be replaced promptly after 5 years of use to prevent the risk of blowouts.
