Engine oil requirements: The GC1723E diesel engine must use oil meeting API CJ-4 or CK-4. In warm climates above 0 °C (32 °F), 15W-40 is the standard choice. For colder starts, 10W-30 or 5W-30 are approved to ensure proper circulation.
The crankcase holds 4.0–4.5 liters with filter installed. Oil should be changed every 100 hours or once per year under normal use, or 50 hours in severe conditions. Synthetic oils are permitted as long as they meet the same CJ-4/CK-4 specification.
The OEM oil filter is Massey Ferguson part 3710280M3, with cross-reference options available. This ensures proper bypass valve calibration and filtration efficiency in line with the engine’s requirements.

Always match filter specs and quality to original equipment. Cheap “fit-all” filters can cause early engine wear.
Even among reputable brands, there can be small differences in filter construction. Micron ratings, bypass valve pressures, and media surface area sometimes vary slightly from OEM design. While these differences rarely affect daily service, operators who want absolute precision should compare technical data sheets before choosing a substitute.
The safest approach is to treat aftermarket filters as acceptable alternatives only when they clearly publish specifications that align with OEM requirements.
Owners often discuss using alternative UTF brands or cross-referenced filters beyond those listed here. While many products from Rotella, Delvac, and other suppliers perform reliably, the key safeguard is that they must carry the same API GL-4 and OEM-equivalent ratings.
Cheaper fluids or “universal” filters may fit, but they rarely provide the same detergency, water resistance, or micron efficiency. Staying within OEM specifications ensures the hydrostatics, wet clutches, and bearings are protected over the long haul, even if substitutions are made for availability reasons.
Why the Right Oil and Fluid Matter for the Massey Ferguson GC1723E
Choosing the best oil for your Massey GC1723E means more than filling to the right level. Diesel-rated, high-detergency API CJ-4 or CK-4 engine oil protects against soot, heat, and sludge in these hard-working sub-compact tractor engines. Using the wrong fluid or a generic oil can lead to poor starts, sticky lifters, smoking, or even expensive DPF failures.
UTF hydraulic fluid for Massey Ferguson GC1723E is engineered for hydrostatic pumps and wet clutches—never use ATF or low-grade farm fluid substitutes.
Manufacturer’s Recommendations and Technical Deep-Dive
Engine Oil:
Only diesel-rated oils meeting API CJ-4 or CK-4 are approved, since these protect emissions systems and prevent DPF failures.
For viscosity, SAE 15W-40 is suited to warm-weather operation, while SAE 5W-30 or 10W-30 remain the correct choices for winter or extended cold starts.
Oil grade should be matched to both climate and workload. For operators who mainly mow or run light attachments in temperate conditions, SAE 10W-30 often provides the right balance of flow and protection.
In contrast, loaders, backhoes, and snowblowers place heavier loads on the small diesel, especially in heat. Under those conditions, SAE 15W-40 or full synthetic options hold viscosity better and resist shear across long duty cycles.
When winters are severe and the machine is expected to start daily, 5W-30 or synthetic 0W-40 offer critical cold-flow advantages. Linking grade choice directly to how the tractor is worked ensures protection matches the real stresses of operation, not just the thermometer.
⚠️ NOTICE: Warranty & Oil Choice — Know Your Rights
There’s a federal law called the Magnuson-Moss Warranty Act that protects you from being forced into buying a specific brand of oil. An OEM can recommend their branded product, but they cannot require it for warranty coverage unless they provide it for free.
What really matters is that the oil meets the published viscosity grade and API/ACEA/Manufacturer specification listed in the Massey Ferguson service manual. As long as you use oil that matches those specs, your warranty remains intact — no matter what brand name is on the container.
After decades in this industry, I can tell you this isn’t unique to Massey Ferguson. Every OEM would prefer to keep you tied to their brand, but the law gives you freedom of choice as long as you stick to the correct specifications. That’s the key to staying compliant while still choosing the oil performance that best fits your workload and budget.

Capacity confirmation is important: While some manuals list 2.6 liters, real-world service confirms the GC1723E requires 4.0–4.5 liters with filter installed. In every case, the dipstick is the final authority for correct fill level.
In practice, a complete drain with filter replacement consistently measures closer to 4.0–4.5 L.
This gap doesn’t mean either number is wrong — it reflects different fill definitions. The dipstick remains the only final authority for correct level.
Synthetic oils are permitted and strongly recommended for sub-compact tractor use in severe climates. They provide superior cold-flow during startup and, with proper oil analysis, can extend change intervals without sacrificing protection.
The OEM chart provides more exact guidance by tying each viscosity grade to specific temperature ranges.
SAE 5W-30 is approved from –35 °C to 40 °C (–31 °F to 104 °F), offering the widest coverage for year-round operation.
SAE 10W-30 is suitable from –20 °C to 40 °C (–4 °F to 104 °F), giving reliable protection in moderate climates.
SAE 15W-40 is recommended for consistently warm regions where temperatures stay above 0 °C (32 °F).
These defined ranges reinforce why climate and season must guide your oil choice, not just general “cold” or “hot” labels.
In extreme cold regions, some operators choose synthetic 0W-40 oils such as Mobil Delvac to ensure easier starting and faster circulation at sub-zero temperatures. This grade is not listed in the OEM chart, but it has a strong record in northern climates where equipment must start reliably in harsh winter conditions.
Owners using 0W-40 should confirm the oil still meets API CJ-4 or CK-4 requirements and monitor performance closely. It remains an adaptation for severe cold, not a factory-specified viscosity.
The reason 0W-40 is debated is that it isn’t shown on AGCO’s viscosity chart. However, several major diesel oils in this grade are fully certified to API CK-4. When those credentials are present, the oil meets the same emission-system protection and wear standards as factory-listed viscosities.
For owners in northern climates where equipment must crank in sub-zero temperatures, this option is a practical adaptation — but it should always be chosen by certification first, not by grade alone.
Hydraulic/Transmission Fluid:
Hydraulic and transmission specification: The GC1723E requires a Universal Tractor Fluid (UTF) meeting API GL-4. Massey Ferguson lists Permatran 821XL as the OEM reference, with approved equivalents acceptable as long as they meet the same standard.
Service intervals are defined: The first hydraulic fluid change is required at 250 hours. After the initial change, the interval extends to every 300–500 hours or two years to maintain system health.
System capacity is significant: The combined transmission and hydraulic reservoir holds about 12 liters in total. This shared system design makes fluid quality and service intervals critical for long-term reliability.
Synthetic fluids are permitted: Synthetic UTF is especially beneficial for extreme climates. It improves cold-weather flow and maintains viscosity stability under high thermal load.
Never use automotive engine oil or ATF—both lack required additives, risking damage and possible warranty denial.
Comparing High-Quality Oils for Massey Ferguson GC1723E
Choosing the best oil ensures optimal performance under heavy loads while minimizing wear on critical engine parts. Independent testing often highlights differences between brands. Below is a breakdown of top-performing oils for the Massey Ferguson GC1723E:
AMSOIL Heavy-Duty Synthetic Diesel Oil: This oil meets API CJ-4/CK-4 and is available in 15W-40 and 10W-30. Independent testing, including the Detroit Diesel DD13 Scuffing Test (DFS 93K222), demonstrated four times greater wear protection than the minimum industry requirement. Its performance makes it suitable for high-stress and extreme use.
Shell Rotella T6 Full Synthetic: Known for resisting oxidation and reducing deposits, Rotella T6 maintains its viscosity under stress and excels in both hot and cold climates.
Mobil Delvac 1300 Super 15W-40: Meets API CK-4 specifications, balances affordability with protection, and is trusted by farm and fleet owners nationwide.
In practice, many GC1723E owners report using a range of well-known diesel oils with good results. Rotella T5 10W-30 is a common choice in moderate climates, while Rotella T6 5W-40 finds favor in regions with wider seasonal swings.
Some operators also rely on Mobil Delvac Synthetic 5W-40 for its cold-start performance in northern states and Canadian winters. These are not factory requirements, but they reflect the practical habits of long-time owners maintaining their machines across varied conditions.
C1723E Oil Filter Replacement: DIY Steps
Preparation is important: Begin by running the engine for about ten minutes. This warms the oil so it drains fully, carrying away suspended contaminants. Shut the tractor down, set the brake, and secure it before starting service.
Drain the system completely: Position a drain pan under the engine and remove the oil drain plug. Allow the crankcase to empty fully before moving to the filter, as partial drainage can leave sludge and debris behind.
Replace the filter correctly: Install a new oil filter, using the Massey Ferguson 3710280M3 or an approved equivalent. Before installation, coat the filter gasket lightly with fresh oil to ensure a proper seal and easier removal at the next service.
Refill and verify: Add 4.0–4.5 liters of the recommended diesel-rated oil, then start the engine and let it idle briefly. Shut it down, check for leaks, and confirm the oil level both hot and cold with the dipstick to ensure accuracy.
Pro Tip: Log every GC1723E oil filter replacement and fluid change with date and engine hours—critical for warranty and resale value.
Total Base Number (TBN) matters: Oils with a high TBN provide additional reserve alkalinity to neutralize acids formed during combustion. This protection is especially important in short-cycle duty where moisture and unburned fuel accelerate acid formation. A stable TBN ensures the oil maintains protective properties between scheduled service intervals.
Many operators still rely on myths when deciding if oil is ready to be changed. Dark oil is often taken as proof that it’s worn out, when in fact it usually means detergents and dispersants are suspending contaminants exactly as designed.
Another common mistake is the so-called “finger test,” rubbing a drop of oil between your fingers to judge condition. This reveals nothing about oxidation, soot loading, or wear metals — all of which determine true oil health.
The only reliable way to know if oil is still serviceable is through laboratory analysis. A proper oil sample reveals viscosity changes, contamination levels, additive balance, and wear metals, giving owners hard data instead of guesswork.
Troubleshooting and Real-World Solutions
Rising engine oil level is a warning sign: If the crankcase level begins to climb above normal, it usually indicates a stuck fuel injector or a hydrostatic transmission leak pushing fluid into the sump. Continuing to run the tractor in this condition risks severe engine damage, so immediate service is required.
Hard winter starting has specific causes: Cold weather thickens conventional oil, stresses the battery, and reduces cranking speed. Switching to a synthetic 5W-30, ensuring the battery is fully charged, and using an engine block heater will improve startup reliability in subzero conditions.
Milky hydraulic fluid indicates contamination: Water intrusion turns the UTF cloudy and quickly compromises lubrication quality. The only remedy is a full system flush and replacement with clean fluid, since running with emulsified oil leads to rapid pump and valve wear.
Hydraulic or transmission whine reflects poor fluid condition: This noise often comes from aged or incorrect UTF in the system. Changing the fluid and refilling with the proper GL-4 approved specification typically restores quiet operation and prevents long-term component damage.
Sub-Compact Tractor Maintenance Schedule
Engine oil and filter changes are routine: Service is required every 100 hours or once per year under normal conditions. In heavy or dusty roles, the interval is shortened to 50 hours to ensure contaminants do not accumulate beyond the oil’s detergent capacity.
Hydraulic fluid and filter service is staged: The first change comes at 250 hours, followed by 300–500-hour or two-year intervals. Operators should also monitor for signs of water or dirt intrusion, since contamination shortens component life.
Air filter inspection protects performance: The element should be checked every 100 hours and replaced at 200 hours. In mowing or fieldwork with heavy debris, earlier replacement may be necessary to prevent restriction.
Fuel filter maintenance prevents power loss: Inspect the fuel filter at 100 hours and replace it between 200–300 hours. If power drops or the engine hesitates under load, early replacement is advised to restore proper fuel delivery.
