Some customers question why Blauparts recommends the Ravenol MTF-1 75W-85 for the front and rear differentials in some Toyota Truck and SUV models?
Gear oil is a very general and broad term identifying the general type of oil. Gear oils can be used in manual transmissions, differentials, axles, transfer cases and even some automatic transmissions.
Gear oil, also known as gear lube can encompass or often be identified by several other terms and names such as manual transmission fluid, transmission fluid, MTF, MT fluid, transfer case fluid, differential fluid, axle lubricant, transaxle lubricant, hypoid gear oil, and others. Many of these names are simply terms to identify a general application or the product name but not the exact use and fitment of the gear oil. The use of a gear oil should always be identified through the vehicle manufactures recommended and desired lubricant part numbers and specifications for that particular gear oil and application. In this case Toyota part numbers 08885-02606 and 08885-81070.
OE Equivalent Toyota Truck and SUV Gear Oil Option
For decades it has been common practice for automotive manufactures and the industry to spec and use one gear oil type in both manual transmissions, differentials, and even some transfer cases. As an example, Ravenol MTF-1 is considered a gear oil. Please note that the Ravenol MTF-1 meets the required SAE 75W-85 viscosity and a GL-5 gear lube specification for the Toyota truck and SUV front and rear differentials. The term "GL" included in the MTF-1 specification list as GL-5 is an abbreviated and by definition equal to the term "Gear Lubricant". You can also note the below part numbers that also indicate the use in the front and rear Toyota Truck and SUV differentials.
Toyota Front and Rear Differential Gear Oil Equivalents
- Equivalent to 08885-81060 European region part number for differential gear oil LT
- Equivalent to 08885-02506 U.S.A and Asia part number for differential gear oil LT
- Equivalent to 08885-02606 and 08885-81070 U.S.A, European, and Asia region part numbers for differential gear oil LX (LSD)
In this instance Ravenol (the lubricant manufacturer) has chosen to label a gear oil as MTF. Ravenol cross references MTF-1 to Toyota part numbers that are recommended for use in the front and rear Toyota differentials (e.g. Toyota Differential Gear Oil LT GL-5 75W-85). This same product is also used by other vehicle manufactures in manual transmissions, differentials, axles, transfer cases and even some automatic transmissions. The most important reference is the OE part numbers listed by the lubricant manufacturer and the viscosity SAE 75w85, and a GL-5 spec.
Our Transfer Case Differential Fluid Change Kits for the Toyota trucks and SUVs were configured for vehicles with original stock factory differentials, using the factory recommended wheel and tire sizes. The Ravenol MTF-1 75W-85 GL-4 GL-5 included in these kits for the front and rear differentials has the necessary additives in the formulation to correspond with and meet Toyota OE part number requirements for both front and rear differentials ‘Differential Gear Oil LT and LX 75W-85 GL-5' applications for stock vehicles.
Ravenol MTF-1 75W-85 GL-4 GL-5 is equivalent to Toyota Differential Gear Oil LT 75W-85 GL-5. Also known and referenced as part numbers 08885-02506 and 08885-81060. No additional additives or friction modifiers are required when using this gear oil in accordance with the above mentioned OE part numbers and corresponding vehicle manufacturer model application recommendations.
In addition, Ravenol MTF-1 75W-85 GL-4 GL-5 is equivalent to Toyota Differential Gear Oil LX 75W-85 GL-5 (LSD). Also known and referenced as part numbers 08885-02606 and 08885-81070. No additional additives of friction modifiers are required when using this gear oil in accordance with the above mentioned OE part numbers and corresponding vehicle manufacturer model application recommendations.
Modified Toyota Truck and SUV Gear Oil Option
Toyota truck and SUV owners with vehicles that are modified or not stock (see note below) and have noticed differential binding and chatter when turning could consider substituting MTF-1 with Ravenol DGL 75w85 GL-5 LS (Limited Slip) for the front and rear differentials (Blauparts part number J1C1144).
Note: Vehicles equipped with oversized wheels, tires, and aftermarket differentials (for off roading or other reasons) will put additional demands on the drive train components such as the differentials ring and pinion. Typical symptoms of additional strains are a wheel chirping noise, along with a binding chatter sensation that occurs in the differentials when turning the vehicle in tight turning situations while the vehicle is moving.
