or you have a choice of "universal" CVT fluids. So, you have either model-specific CVT fluids - genuine Honda, genuine Nissan, etc. These are just as effective as the OEM brands and are usually considerably cheaper! However, due to the overall growth in popularity of CVT-equipped vehicles (there are now more than 200 different models on the road), other lubricant manufacturers developed their own products. Because of this limited use, they were, and still are, comparatively expensive. A new type of fluid was needed.Īt the time, because of differences in the technologies used, each of the car makers developed their own CVT fluids. When new models were being developed in the early 2000s, manufacturers realized that existing automatic transmission fluids weren't up to the job. The problem with CVTs is that they can run very hot, leading to excessive wear, the belt or chain slipping or vibrating, and even component failure. That, in turn, means better fuel economy. The CVT "gearbox" responds precisely to the demands of the engine so you get smooth and very efficient power delivery. The idea is basically that instead of stepped gears - with their restricted ranges - a belt or chain runs between two conical pulleys. The idea of a continuously variable transmission dates back to the 15th century and Leonardo da Vinci, although it wasn't until the end of the 19th century that it saw commercial use in sawmills, then later in road vehicles. Why are we seeing CVT fitted to more vehicles? It's a high-performance alternative to many factory-spec fluids, at a much more competitive price. We have several recommendations, including our top pick, Valvoline's CVT fluid. We've been looking at the subject in detail so we can help you make the right decision. As a result, greater care is needed when choosing them. However, CVT fluids are more complex than those used in ordinary automatic transmissions, and they can be much more model-specific. In the ongoing search for lower motoring costs, continuously variable transmissions (CVT) are becoming increasingly popular.
