Cheapest, sure way to get jugs
Some stores around me don’t not offer jugs, only place to find 3-case jugs and for CHEAP! the closet store brand isn’t about 40 for Dextron 6. So I recommend.

Seems like Good Fluid and Much cheaper than Dealership/OEM fluid
So far I am highly impressed. I used this fluid on a 2009 Mitsubishi Lancer ES with 109k on it. This CVT fluid is a fraction of what the OEM JT1 fluid would cost. I did this with a pan drop and filter change as well. Thank you for other reviewers who noted that transmission shifted roughly after the change. That way I didn't lose it the first few miles thinking I had killed my CVT. I observed this too. Mine took about 30 miles to finally even out and now the change is dramatic. I must note I just got this car and I am not sure if fluid or filter was ever done but the CVT is transitioning between ratios much smoother now. I did have a lot of whine in my CVT before the change and I have not noticed any yet but I really have yet to take a long trip to warm the CVT enough to get the whine. I will try to update on my next long trip or the next change at 140k Miles Edit 1: about 1200 miles in a things are going well. I wanted to update that the CVT whine is gone. took a 2-hour drive to get good and warm but no whine like before. CVT is nice and quiet. Will update again if anything major happens before 140k Edit 2: CVT strikes This fluid is done by 22k miles. about 8k before recommended service. On a longer trip the whine came back and got a temp warning for transmission. Slowed down and it went away but checking fluid color is pretty bad and I have about 22k on fluid so going to change at every 20k now. I don't believe this is the fluid's fault I think this is just the nature of the CVT. CVT is still shifting good and no chattering just fluid is broken down quicker than expected. I do live in Texas and high heat may have added to this but not sure. I will how ever be using Castrol again as I think its doing pretty good so far.

Good product good value!
2014 Nissan Rogue S (NS-3)had slipping issues. Complete drain and fill including flushing out the torque converter. Cycled the new fluid 400-500 km. Worked great! $35 quart at the stealership Yikes!

Perfect in the Merc 722.n Gearbox.
This stuff meets the Dexron II and III requirements my Mercedes-Porsche auto gearbox demands. Many more modern "works in anything" fluids are nothing but problems for 'vintage' euro GT cars. This one works perfectly. I'm very happy that this is still available. A few local stores stock it, but at a cost premium. Thank goodness Jeff B. had an old Mercedes, and keeps bottles of this for me in his warehouse/garage.

Altima 2011
Excelente aceite, le hice servicio a mi altima 2011 con 230,000km xq haría un viaje desde chihuahua a mazatlan y todo quedo al 100, le vacíe lo más que pude del aceite viejo que fueron 7 litros por lo que tube q pedir otra caja xq solo viene de 6, hasta ahorita el carro ha duncionado muy bien sin ningún problema, pienso sacarle un litro de aceite a la transmisión y ponerle uno nuevo cada 6 meses de los 5 L que me quedaron y así asegurar que todo el aceite fue cambiado al 100%
