I use this in two Chevy vehicles - a 2005 Colorado and 2015 Trax. The Trax takes 3-qts to drain and fill. The Colorado requires 6-qts when the pan is dropped and filter replaced. Both vehicles perform at higher levels after an ATF service. I have used Valvoline ATF for many years and will continue to.

I purchased 5QTS to complete a drain and fill on my 2019 Ford Escape with the 6R35 Transmission -- this is not "officially" licensed by Ford but is recommended by Valvoline for use with the Mercon LV specs-- the transmission is a joint development from Chevrolet and Ford - I compared the specs from the Mercon LV fluid and the ONLY difference is the viscosity at -40C - not even a concern for the climate I live in. After the drain and fill my car shifts smoother and softer, it's has pep, and I feel like it drives like the day it was purchased. I would def purchase again to keep on schedule with my transmission maintenance. I can't comment on longevity as of yet seeing the change just happened but I will say after doing research and knowing how the Mercon LV fluid degrades over time I'm hopeful this will be more durable since it is a synthetic fluid. Time will tell. All that to say if you have Ford that requires LV -- don't stress it -- order it... it works!

I have been using this since I built a new trans for my daily driver. I have used this 4 times in a row, the fluid seems to hold up well. I do not see much "sludge" in the bottom of the trans pan (there is always some in an automatic, but it does seem to be notably less on this fluid). It still looks mostly clean and of a nice slightly darker pink color when I flush it around 36,000 miles. I have never seen this fluid burn or discolor badly, though I do not run extreme intervals. I am confident that I could push this fluid well beyond the 36,000 mile recommended interval from GM for my 2008 car ( I know a lot of newer cars have longer intervals) but do not see a reason to take the risk. Dexron VI is a good fluid spec anyway, buy I view the extra few dollars for a good synthetic as a small insurance policy to keep my transmission healthy. I would recommend the fluid, but I would also recommend looking for a sale price on it. Also, ignore the 2 star rating, seems irrelevant, and is only disappointment that Dexron VI is not a lower spec fluid? Not actually a review of this fluid.

K&N is the only way to go for air filters!! Nothing gets through except more air. They are expensive, but they don't ever have to be replaced. Just clean them every 6 months and recharge with the oil spray. Only filters I trust. Been using them for 20+ years.

I have used Valvoline in all my cars for over 40 years.....and have NEVER had any of them burn oil. I'm so glad that they make a 0W-20 European synthetic motor oil certified for use in my VW GTI. It's great product at a great price!

I use Valvoline in all of my vehicles. I use High mileage 5w30 Syn blend on my 08 Sierra. This oil gives me a good four to five thousand miles between changes. Truck purrs like a kitten. Great oil for cold starts in the winter. I highly recommend.

I had a quick rattle on startup 2007 Mustang 4.6 L @ 58K miles. I tried other premium oil and filters and was beginning to think it was a more serious mechanical issue. I switched to this oil and a (another brand ultra-synthetic) filter (because they don't sell Pennzoil filters in my area), and the noise was instantly gone. From the first crank, no more. Startup is smooth, quick, easy. Motor and car run noticeably smoother. The product says it provides the same protection as 5W-20, so I'm covered there. Looking forward to trying this stuff out.
