What is the difference between natural gas engine oil and synthetic engine oil?
2 Answers
The differences between natural gas engine oil and synthetic engine oil are: 1. Different raw materials: Natural gas engine oil is made from natural gas; synthetic engine oil is made from ethylene and propylene dispersed from gas or natural gas in oil. 2. Different production methods: Natural gas engine oil is produced through chemical synthesis or refining processes; synthetic engine oil is manufactured through polymerization and catalytic chemical reactions. The method for adding engine oil is: 1. Lift the car, remove the protective plate, and place a container of about 10 liters under the oil drain screw; 2. Unscrew the oil drain screw, use an air gun to blow for two minutes at the oil filler port, tighten the oil drain screw after draining, and wipe it with a tissue to check for oil leaks; 3. Reinstall the protective plate, lower the car, and use a funnel to add oil through the filler port.
I often drive long distances and have noticed significant differences between natural gas engine oil and synthetic oil. Natural gas engine oil is primarily produced from natural gas through conversion technology, containing very few impurities. It makes the engine run smoother and reduces noise. Synthetic oil, on the other hand, is chemically synthesized, usually derived from petroleum-based sources, and remains more stable at high temperatures, making it suitable for high-speed driving. I think natural gas engine oil is more environmentally friendly and better for engine cleanliness, but it's a bit more expensive, costing around a few dozen yuan more per barrel. Synthetic oil is more widely available and offers good value for money, especially for older cars or city commuting. In short, both can protect the engine—just choose based on your budget and driving habits. When changing the oil, always ask the mechanic for advice to avoid pitfalls.
