What engine oil does Cummins use? Comprehensive analysis of engine oil selection guide
Cummins engine is a world-renowned power equipment, and its oil selection directly affects engine performance and life. This article will combine recent hot topics and hot content to provide you with a detailed analysis of the oil selection standards, recommended models and usage precautions for Cummins engines.
1. Cummins engine oil requirements
Cummins engines have strict technical requirements for engine oil, mainly including viscosity grade, API specifications and Cummins exclusive certification (such as CES standards). The following are the engine oil technical standards officially recommended by Cummins:
| Engine series | Recommended viscosity grade | API specifications | CES certification standards |
|---|---|---|---|
| ISB/QSB series | 15W-40 | CK-4/FA-4 | CES 20086 |
| ISC/QSC series | 10W-30/15W-40 | CK-4 | CES 20081 |
| X series | 5W-40/10W-30 | CK-4/FA-4 | CES 20085 |
2. Recommended popular engine oil brands (search data in the past 10 days)
According to the search and discussion popularity on the Internet in the past 10 days, the following engine oil brands are the most popular among Cummins users:
| brand | Popular models | Applicable engine | attention index |
|---|---|---|---|
| Mobil | Delvac 1300 Super 15W-40 | full range | ★★★★★ |
| Shell | Rotella T6 5W-40 | X series | ★★★★☆ |
| Castrol | Edge Heavy Duty 10W-30 | ISC/QSC | ★★★★ |
| Total | Rubia TIR 9900 15W-40 | ISB/QSB | ★★★☆ |
3. Three key factors in engine oil selection
(1) Climatic conditions:In cold areas, it is recommended to choose 5W or 10W engine oil with better low-temperature fluidity, while in high-temperature areas, 15W or 20W oil is recommended.
(2) Engine operating conditions:Engines that operate under high load for a long time should choose a higher grade CK-4 specification engine oil and shorten the oil change interval.
(3) DPF configuration:Engines equipped with DPF aftertreatment systems must use low-ash (CJ-4/CK-4) oil to avoid clogging the filter.
4. Answers to recent hot questions
Q: Can FA-4 engine oil be used in National VI Cummins engines?
A: The latest research shows that Cummins officially allows some National VI models to use FA-4 10W-30 engine oil, but it must comply with CES 20085 standards. Please check the engine manual for details.
Q: How to determine the oil change interval?
A: Based on recent user discussion data, the general recommendations are as follows:
| Usage environment | mineral oil | Semi-synthetic | Fully synthetic |
|---|---|---|---|
| Normal working conditions | 250 hours/15,000 kilometers | 400 hours/25,000 kilometers | 600 hours/40,000 kilometers |
| Harsh working conditions | 150 hours/10,000 kilometers | 250 hours/15,000 kilometers | 400 hours/25,000 kilometers |
5. Precautions for use
(1) Avoid mixing different brands of engine oil. Recently, some users reported that oil sludge increased due to mixed oil.
(2) Pay close attention to the oil pressure alarm. The latest cases show that inferior engine oil can cause early wear.
(3) National VI engines must use special engine oil with DPF protection formula
(4) It is necessary to avoid high-temperature environments when storing engine oil. Recent high-temperature weather has caused many engine oil deterioration problems.
Conclusion:Choosing an engine oil suitable for Cummins engines requires comprehensive consideration of technical standards, operating environment and engine characteristics. It is recommended to regularly check the engine oil condition through Cummins Insite software and strictly follow the maintenance plan according to the maintenance manual.
