What kind of oil your tractor needs tips for choosing Blog

As the summer temperature rises, it is important to make sure your tractor is operating properly. One of the best ways to avoid major mechanical problems is preventive maintenance. Changing the oil regularly keeps the mechanical parts working.

The owner’s manual for your tractor will tell you how often to change the oil based on the hours of use of the tractor. For tractors that are used less frequently, a good rule of thumb is to change the oil every twelve months. Even when a tractor is not in use, contaminants and moisture can build up on the engine and cause increased wear on moving parts, which can lead to costly and avoidable repairs.

Your owner’s manual should contain the specific information you need for your model. If you want to change the oil in your tractor yourself and you don’t have a manual, here’s what you need to know.

If you have a Kubota tractor, buy Kubota oil and filters. If you have a John Deere tractor, buy John Deere oil and filters. Doing this will probably cost you a bit more, but remember that the manufacturer’s oil is formulated for your tractor. If you have an engine failure, the first thing the manufacturer will ask you for is an oil and filter sample. If the machine is under warranty and you are using a different brand oil, you could put your warranty at risk. We have seen it.


Recently, your tractor oil has been reformulated to meet new emission and efficiency standards, and your manual may not have updated information.

Due to new fuel efficiency and emissions requirements, we now have two new types of motor oils. CK-4 and FA-4 heavy engine oils have been formulated to withstand the higher temperatures generated by new generation engines, designed to run cleaner and more efficiently.

Your first consideration is the age of your computer. The CK-4 is formulated to be compatible with all engines, including older model tractors. It is available in the same viscosity and weight classifications that you have always used; for example, 30W, 15W40, and 20W50.

CK-4 is also available in different types of oil: conventional, fully synthetic, and synthetic blend. Therefore, you will use the same type of oil that you have always used, but of better quality.

FA-4 motor oils are designed for newer tractor engines and have limited compatibility with older ones. Lower viscosity grades make them the perfect protection for new fuel efficient and low emission engines, but should not be used on older models.

From API:

FA-4 oils are neither interchangeable nor backward compatible with API CK-4, CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 oils. Refer to engine manufacturer recommendations to determine if API FA-4 oils are suitable for use. API FA-4 oils are not recommended for use with fuels having greater than 15 ppm sulfur. For fuels with sulfur contents greater than 15 ppm, refer to engine manufacturer recommendations.

Read the label carefully to determine which oil can be used in your model, and if in doubt, ask a knowledgeable professional. We always have someone available to answer your questions.


You will need to gather some basic information:

  • Make, model and serial number of your tractor. Your local dealer should be able to find specific recommendations for your engine.
  • It is essential that the amount is correct. Too much or too little is a problem. Owner’s manuals can be a bit imprecise as to the exact measurement, as they often cover more than one model. Consult with a trusted dealer. If all else fails, pour the old oil into a container and measure the approximate amount.
  • What size and type of oil filter do you need? When changing the oil, always evaluate the oil filter. There are two types of oil filters, screw-in and cartridge. Cartridge filters (they are not used that often) are housed in a container and inserted. Although changing the oil in your tractor is not complicated, it must be done correctly and on time. If you are unsure about any aspect of the process, consult an expert or take it to your dealer for review rather than doing it yourself. Above all, avoid ruining an expensive piece of machinery through negligence or poor maintenance. Done right, your machine (and your investment) can last for decades.

A good tractor salesperson will tell you exactly how much oil you need.A secret.If you take your serial number to a dealer, they can tell you almost everything about your tractor.They can tell you all about your transmission and the engine work that has been done under warranty.It is like a social security number.Tractors have no title.This is why serial numbers are so important.We always encourage our customers to have their model and serial number handy when they visit us.
