Idemitsu30040097-95300C020 ATF Type HK Automatic Transmission Fluid - 5 Quart

We have an ‘09 Santa Fe V6 with 260,000 miles. I routinely change the ATF ( drain and fill twice leaves about 75% fresh fluid) every 30k miles. I had always send Valvoline due to its availability. This time I gave Idemitsu a shot after reading it was Hyundais fluid.The only noticeable difference that I think I notice is more torque steer upon acceleration. I thought I was imagining things, but I was not. The only thing I can attribute this new-found torque steer to is the new ATF, and the torque converter working more efficiently because of it.

Idemitsu is a huge fluid manufacturer that often manufactures OEM fluids for the factory. That means, instead of spending the money at the dealership to have, for instance, the Acura logo on the bottle, buy the correct Idemitsu fluid and you are getting the identical product, just in their own packaging.Idemitsu makes a wide range of vehicle-specific fluids and I have used them exclusively in my Volvo, Acura and Kia with no issues whatsoever. The value is far better than paying dealership prices. Idemitsu is a factory-fill for many Japanese and other manufacturers. You can read more on their website but here is a little clue:Almost 20 years ago, Idemitsu partnered with Honda to develop a lower viscosity oil to boost fuel economy in their hybrid vehicles. After rigorous testing and refinement, Honda began to fill their new Insight Hybrid at the factory with Idemitsu 0W-20. This lower viscosity higher grade synthetic oil used unique additives to enhance stability and reduce volatility – the typical drawbacks of low-viscosity oil.Shortly after, in 2005, Honda began filling non-hybrid vehicles with Idemitsu 0W-20. Other automakers quickly took note and soon, all the major Japanese brands followed suit. Nissan began using it in 2006, as did Toyota in 2009.Idemitsu brought 0W-20 stateside in 2010. Since then, it has been the factory-fill oil of millions of Honda, Toyota and Nissan vehicles made in America. And with mounting government pressure to increase fuel economy, US automakers are now looking at 0W-20 as a viable option.So if these manufacturers, known for their quality, trust Idemitsu Lubricants for their vehicles from the factory, why wouldn’t you?

If you want to save money do the research. Hyundai uses this product just puts thier name on it and charges more.

Like oem

Works great in my 09 Hyundai Accent I bought a couple quarts of the Hyundai sp-III first then found out about this wish I would have never spent the money on the Hyundai fluid cuz this idemitsu is way cheaper and works just as good I really think it’s the same fluid to be honest why buy that expensive Hyundai fluid when u can buy idemitsu for way cheaper especially if u just buy the 5 quart jug just saying ur choice tho
