I really enjoy reading about all the homemade engineers that are smarter than the people who actually designed and built the car. Everyone always believes their oil will somehow be so much better and they are so hard headed, they will believe its actually working better too. I've worked on Hondas for over 20 years. I've rebuilt countless manual transmissions. I've tried multiple oils and seen what all different kinds can do.
Honda MTF is always the best, there are no problems at all with it, and it makes perfect sense to just keep it in there and continue using it. The people who say "oh I used so and so on all my cars and i'll never use anything else And us mechanics who have spent 40 years fixing stoopid engineers screw ups know they don't know shit.
Don't give me any engineer BS, those guys are all ego and no sense. You do NOT want to overfill it, but if you get it warm first, drain it all out, and only put 2 quarts in, it won't be overfilled. Is that what it says in the service manual? In nissans, they give you an estimated capacity and you fill it until it starts to flow out of the filler hole then close it Froz3nTundra Senior Member.
Additionally, synthetic manual transmission oil offers better performance over a wider temperature range. The composition of the oil varies from one manufacturer to the next but will contain the following:. There are two important figures when it comes to manual transmission fluid: performance and viscosity. The American Petroleum Institute API created a system for automotive gear oils, giving them a gear lubricant GL number as a guide to how they work with the various metals in the transmission.
The numbers range from GL-1 lightest to GL-5 heaviest. Viscosity is a more complex subject. At high speeds and with new transmissions in good physical condition, you ideally want low-viscosity thin oil.
However, under heavy load, you want high-viscosity thick oil. The latter is also better at protecting components from wear. So all types of transmission fluid, indeed all types of engine oil, are something of a compromise.
The Society of Automotive Engineers SAE developed a system of viscosity ratings that has been adopted by both motor manufacturers and fluid producers and is recognized worldwide. The higher the number, the thicker the oil.
Monograde: These types of oil were widely used until the s and still are in some racing engines. They typically maintain performance for longer than multigrades. Multigrade: But nobody wants to be changing their transmission fluid with the seasons. Multigrades are the answer.
The most advanced multigrades have taken this a step further. A decade ago, you almost always bought oil based on the SAE number. In general, when we compile our reports, we like to offer a guide to inexpensive, mid-range, and expensive products.
The amount of manual transmission fluid your vehicle needs can be anywhere from 6 to 16 quarts, so a difference of five bucks a quart soon adds up. At the end of the day, the most important factor is getting the right manual transmission fluid for your vehicle. If you find several that are suitable, you can then compare prices.
Used in heavy duty manual transmissions, final drives and axles, high temperatures will not effect the heavy film left by this oil. Accordingly with SAE, oils are divided into types depending on the viscosity index.
In temperate climates, it is advisable to choose greases such as 75w85, 80w90, 75w For hot conditions, the use of 75w oils is optimal. The 80w90 gear oil can be used in extreme pressure conditions and as a lubricant for non-synchronized manual transmissions in heavy duty trucks or buses. This gear oil is recommended for conventional and limited slip differentials.
Information on which type of motor oil is recommended for use in certain vehicles is prescribed in the operating manual. This inscription on oil means that it is universal and can be used both in winter and in summer, and the temperature range of its use will depend on 75W standards in winter and in summer. If dealership says to use 75W oil but not 75W Use whats reccommended unless you feel like shelling out the money for a new rear axle.
Depending on the scope of use, oils are divided into types that reflect the technical characteristics and the possibility of application in any unit.
GL-5 oil is recommended for heavier gears e. This is due to the fact that the EP package contains sulfur-phosphorus elements that can cause corrosion of non-ferrous alloy parts. Thus, GL-4 is typically used for synchronized gearboxes, and GL-5 for axles and gearboxes. For front-wheel drive cars, as Corrosion control of synchronizers can go against the protection of final drive gears, because they are in the same block.
Just remember that GL-4 and GL-5 are gear oil ratings, not transmission oil ratings. Between 75w90 motor oils from different manufacturers there is a difference both in characteristics and in cost.
Usually this oil product is synthetics. Sometimes manufacturers write on the canister that it is a semi-synthetic gear oil. From synthetic it has only one difference, which consists in a small content of filler substances. I write reviews and guides, helping people to choose the most suitable technicals and best product for them.

How can the fluid level of the manual transmission be checked? However, if you still wish to carry out this operation yourself, here is our advice. Before starting to check the transmission oil: Get a cloth or a roll of paper towel.
Refer to your service manual to find out what transmission fluid your transmission needs and how often it should be changed. In this manual, you will also find the location of the fuel filler cap.

How do I choose transmission oil for cars?
Classification by Performance Widely accepted, though not the only one, is the API lubricant classification, developed by the American Petroleum Institute. It divides the gear greases for mechanical gears into several groups, depending on the performance, quantity and quality of the additives: GL-1 — transmission oil with no additives; GL-2 — used in worm gears mainly in agricultural machinery; GL-3 — for manual transmissions and truck axles, not suitable for hypoid gears; GL-4 has extreme pressure, anti-wear, and other additives and is used for manual transmissions and steering gears; GL-5 is designed primarily for hypoid gears, but can also be used for other types of manual transmissions if the car manufacturer provides it.
Characteristics of SAE gear oil SAE parameter viscosity grade characterizes the changes in oil viscosity at different temperatures and allows transmission oils to be divided into three categories: Winter oil — SAE 75W works well in the cold season has the letter W in the marking Summer oil — SAE and , used in warm seasons or in states with a hot climate, in moderate climate it is desirable to use oil of class 90 letter W in the marking is absent Multigrade oil — SAE 75W, 80W, and 85W is recognized as universal and suitable for year-round use summer and winter grade marking.
