Should Volkswagen Bora use 5W30 or 40 engine oil?
1 Answers
Volkswagen Bora originally uses SM5W-40 semi-synthetic engine oil. The replacement capacity is 4L, and the replacement cycle is 10,000 kilometers. For later maintenance and oil changes, you can choose brands such as Mobil, Shell, Castrol, and Total. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it maintains viscosity at high temperatures, which can also be understood as better lubrication performance under high temperatures. The method for changing the engine oil in a Volkswagen Bora is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine for 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add new engine oil through the oil filler cap on the engine valve cover, usually filling about three-quarters of a 4L bottle; Start the engine and let it run for 5 minutes, then check for oil leaks around the drain plug and oil filter. If any leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to check if the oil level is within the standard range.
