2. Key indicators for oil selection of iron engines
According to the consensus of professional technicians and popular discussions, the following parameters need to be focused on when choosing engine oil:
| parameter | Recommended range | Reason description |
|---|---|---|
| API level | SL level or above | Meet basic protection needs |
| Viscosity (SAE) | 10W-40/15W-40 | Adapt to the thermal expansion and contraction of the iron cylinder |
| Zinc content (ppm) | 800-1200 | Protect camshaft and other components |
| Base value (TBN) | ≥7 | Neutralize acidic substances |
3. Comparison of actual tests of popular engine oil brands
According to the actual test video of Douyin and feedback from the forum owners, the following three engine oils performed outstandingly in iron engines:
| brand | model | advantage | Applicable to vehicle age |
|---|---|---|---|
| Shell | Rimula R4 15W-40 | Strong cleanliness | More than 10 years |
| Mobil | Super 3000 10W-40 | High temperature protection | 5-15 years |
| Great Wall | Jinjixing J600 15W-40 | High cost performance | More than 8 years |
4. Analysis of common misunderstandings of car owners
1.Misconceptions:Synthetic oil must be better than mineral oil
fact:When designing old iron engines, they are mostly targeted at mineral oil, and some synthetic oils are not sealed enough
2.Misconceptions:The higher the viscosity, the better the protection
fact:The use of 20W engine oil in the north in winter may cause difficulties in starting. Please refer to the manual to select it.
3.Misconceptions:Adding engine oil additives can enhance protection
fact:Most additives will destroy the ratio of engine oil, and well-known brand engine oil already contains necessary additives
5. Maintenance suggestions (combined with hot search terms)
1.Oil change cycle:Recommended to not exceed 5000 km or 6 months (20% shorter than aluminum engines)
2.Machine filter selection:Preferred metal shell filter element (Top 3 of the hot searches in Kyoto: Man brand W7015)
3.Hot car tips:Idle speed for 1-2 minutes after starting in winter (the key emphasis on popular teaching videos on Douyin)
Summarize:Iron engines should choose mineral oil or semi-synthetic oil with high zinc content and appropriate viscosity. Regular replacement is more important than pursuing high-end engine oil. It is recommended that car owners make reasonable choices based on the actual working conditions of the vehicle and combine them with the above data.
