Agricultural equipment continues to evolve at a rapid pace, and with it, the demands placed on tractor transmission oil have never been higher.
Farmers, fleet managers, and heavy-equipment operators depend on lubricants that can withstand harsh conditions, deliver consistent protection, and ensure machinery runs at peak performance with minimal downtime.
While Mobilfluid 424 has been recognized as a reliable multipurpose tractor lubricant, many operators today are switching to what has become widely regarded as the best Mobilfluid 424 equivalent: Shell Spirax S4 TXM.
This premium universal tractor transmission oil (UTTO) has become a top choice for agricultural equipment thanks to its performance advantages, OEM recognition, and ability to support long, productive service life under demanding conditions.
Universal Tractor Transmission Oil (UTTO), also called universal tractor fluid, is a multifunctional lubricant engineered specifically for agricultural and commercial equipment.
Unlike single-purpose lubricants, UTTO is formulated to perform across several critical systems within a tractor, including:
Because agricultural tractors operate under variable loads, temperatures, terrains, and hydraulic demands, UTTO must provide:
A high-quality UTTO ensures precise, responsive machinery operation while preventing the premature wear and failures that can lead to downtime—one of the most costly challenges in agriculture.
The best Mobilfluid 424 equivalent on the market is Shell Spirax S4 TXM.
Mobilfluid 424 is a multipurpose tractor lubricant known for supporting transmissions, hydraulics, PTO systems, and wet brakes in agricultural and commercial tractors.
But in recent years, many operators have shifted toward its Shell counterpart for improved performance, broader equipment compatibility, and greater long-term value.
Designed for modern agricultural machinery, Shell Spirax S4 TXM is evaluated against the newest specifications from key equipment manufacturers, including John Deere, Massey Ferguson, CNH, and ZF.
This makes it an ideal replacement for Mobilfluid 424 while often delivering enhanced performance benefits that align with the needs of today’s equipment and operating environments.

Shell Spirax S4 TXM is a premium UTTO formulated for use in transmissions, hydraulics, wet brakes, and other systems across a wide range of agricultural and off-highway machinery.
It is engineered with:
Whether used in tractors, loaders, or ancillary equipment, Shell Spirax S4 TXM supports smooth hydraulic response, consistent gearshift performance, and quiet brake operation.
Importantly, it is not intended for use as an engine oil, as its formulation is designed specifically for hydraulic/transmission/brake systems.
Shell Spirax S4 TXM is approved or recommended for use across a wide variety of OEM specifications and equipment types. It is suitable for:
This broad compatibility is one of the reasons Spirax S4 TXM is gaining increasing adoption among operators seeking a single, high-performance tractor transmission oil across mixed fleets.
The advanced technology built into Shell Spirax S4 TXM provides measurable advantages to agricultural users.
Shell Spirax S4 TXM uses cutting-edge additive technology including:
For agricultural operators, these benefits directly support:
During peak seasons—planting, harvesting, material handling—downtime is not an option. A fluid like Spirax S4 TXM pays for itself in uptime.
Operator comfort has a measurable impact on productivity and long-term equipment health. Spirax S4 TXM contributes to a smoother operator experience through:
On the farm, where equipment may be used for long days across varying conditions, smoother braking, more responsive hydraulics, and quieter operation all enhance comfort and reduce fatigue—especially important for shop owners and fleet operators with high daily tractor usage.
Spirax S4 TXM is tested and approved by leading manufacturers of agricultural machinery.
This matters because:
OEM approval gives operators confidence, especially when replacing an existing product like Mobilfluid 424.
Spirax S4 TXM includes special friction-modifying additives designed to:
Given that agricultural tractors frequently operate on slopes, rough terrain, and under varying loads, consistent brake performance is essential for both safety and precision.
The formulation of Shell Spirax S4 TXM allows it to withstand maximum operating temperatures, which helps maintain viscosity and protect transmission and hydraulic components under extreme load.
In agriculture, equipment often operates at full hydraulic output, under heavy PTO load, and in high ambient temperatures day after day. A UTTO capable of resisting thermal breakdown ensures better protection, longer equipment life, and fewer costly repairs.
