What hydraulic oil does Kubota use? Comprehensive analysis of models and selection guide

In the fields of agricultural machinery and engineering machinery, Kubota is known for its reliability and efficiency. As the "blood" of the hydraulic system, hydraulic oil directly affects the performance and service life of the equipment. This article will combine hot topics on the Internet for the past 10 days to answer the hydraulic oil selection questions of Kubota equipment in detail and provide structured data references.

1. The hydraulic oil model officially recommended by Kubota

What hydraulic oil does Kubota use?

According to Kubota's official technical manual and user feedback, the following are the hydraulic oil standards for common models:

Equipment TypeRecommended hydraulic oil modelViscosity gradeApplicable temperature range
Tractor (L series)Kubota UDT hydraulic oilISO VG 46-20℃~50℃
Excavator (KX Series)Kubota SUPER UDT2ISO VG 32/46-30℃~60℃
Harvester (PRO series)Kubota BIO HYDRANISO VG 46-10℃~40℃

2. Guide to selecting alternative brands of hydraulic oils

If you cannot obtain original hydraulic oil, you can choose a third-party brand that meets the following standards:

Standard requirementsInternational certificationRecommended Brands
Comply with JIS K2214 standardISO 11158Shell Tellus, Mobil DTE
Wear resistance ≥300 hoursDenison HF-0Castrol Hyspin
Oxidation stability ≥2000 hoursASTM D943Great Wall Anwei 40

3. Hot topics in the past 10 days: Misconceptions of hydraulic oil use

1."Mixed use of different models" problem: A user caused abnormal noise in the hydraulic pump due to mixed UDT and SUPER UDT2, and the maintenance cost exceeded 10,000 yuan.

2."Low Temperature Start Protection" Dispute: Northern users discuss whether preheating hydraulic systems is needed in an environment of -25℃, and experts recommend using low-temperature HVLP hydraulic oil.

3.Risk of "extended oil change cycle": Popular Douyin videos show that the hydraulic oil metal particles that have been used for 200 hours exceed the standard by 15 times.

4. Reference for hydraulic oil replacement cycle

Working conditionsReplacement cycle is recommendedTest indicators
Standard working conditions (<50℃)1000 hours/yearViscosity change ≤10%
Heavy load conditions500 hoursMoisture ≤0.1%
Dustful environment300 hoursPollution NAS Level 9

5. Purchase suggestions and precautions

1.Recognition certification mark: Genuine packaging should have Kubota pure parts anti-counterfeiting code (new QR code verification is added from 2023).

2.Seasonal adjustment: It is recommended to use SUPER UDT2 low-temperature type in winter, with a freezing point of up to -40℃.

3.Storage requirements: Unopened hydraulic oil has a shelf life of 3 years and needs to be stored in an environment of 5℃~35℃ from light.

From the above structured data, it can be seen that Kubota equipment has specific requirements for hydraulic oil. It is recommended to give priority to the use of original designated oil products. When choosing alternative products that meet international standards in special circumstances, be sure to check the matching of technical parameters. Regularly detecting the hydraulic oil status can effectively extend the service life of the equipment by about 30% (according to Kubota Laboratory data).
