Valvoline Advanced Full Synthetic 75W-140 Gear Oil

Used these Flexfill packs to change both diffs and transfer case on my 2016 4Runner. The bag design is fantastic. It allows you to put the spout in the fill hole first and then lift the bag and squeeze to start the flow. Reverse to stop if you need to reposition. I will always use these in the future.

It's Valvoline Synthetic Gear Oil... it should be fine.

2004 WJ Jeep Grand Cherokee, with Dana 35 rear. Happy Diff, quiet again, and exactly what the build tag calls for "75W-140 SYN" I like that it has added Friction modifier already...saves me a step and extra cost. This diff now has over 200k on it and is working fine. This is a good all around oil for most vehicles. If you have something highly specified like a Mini or a Vette, better read your manual.

[This review was collected as part of a promotion.] This gear oil was super easy to use, it didn't get all over my driveway. I love the concept of the bags. So much easier to get into tight spaces. This gear oil is top quality and really good oil for my vehicle

[This review was collected as part of a promotion.] This is a great gear oil. I like that it comes in a bag it makes it so much easier to use. I got it just in time to do all my pre winter maintenance. I continue to be very impressed with Valvoline brand products.

[This review was collected as part of a promotion.] Valvoline FlexFill 75W-90 Full Synthetic Gear Oil exceeded my expectations. Its smooth performance and enhanced protection make it a top choice for my vehicle. Easy to use and reliable, it deserves a solid 5 stars.

[This review was collected as part of a promotion.] I used this to replace my rear differential fluid in my K1500 and this is much easier than using bottles. The bag can get up at a better angle for filling so you don't need any transfer pumps to fill. It's got positrac additive in it already so you don't need any additional additives for limited slip. Great product

[This review was collected as part of a promotion.] This is an excellent oil product for a variety of uses. I used it in a Dana 44 axle. Excellent viscosity and the soft container allowed for no mess, easy pour of the oil into the differential pumpkin.

[This review was collected as part of a promotion.] Flexible pouch for easier use with less waste in tight, hard to reach undercarriage situations. Exceptional high and low temperature protection ranging from -30F to 300F degrees for dependable coverage year-round.

[This review was collected as part of a promotion.] This works great. I love the flexibility of the packaging. It made using it sooo much easier. I could get it where it needed to be without any issues. The oil itself is good quality oil like you'd expect from valvoline.

[This review was collected as part of a promotion.] How has no one thought of this pouch before?? It is so much easier to get into tight spaces than a typical oil bottle. I haven't had any leaks or burning smells since swapping out my rear diff oil about 2,000 miles ago. Would recommend.

[This review was collected as part of a promotion.] i've been using valvoline oil for years for various applications and have always been pleased. i send my used car oil away for analysis and always get good readings. not sure how much of that is my maintenance and how much is the oil but i gotta think the oil quality helps. also, the bag is a fantastic invention and helps get the oil into tight spots underneath vehicles/equipment.

[This review was collected as part of a promotion.] The Valvoline FlexFill Full Synthetic Gear Oil has unique new flexible pouch makes getting into the tightest places to lubricate gears easier than ever and with less waste. The superior detergent package-based formulation contains fully synthetic basestocks and special additives that help protect parts from rust and corrosion while providing exceptional high and low temperature protection and excellent thermal stability, especially in demanding driving situations such as towing and off-roading. It contains an extreme pressure additive for better load carrying capacity, wear resistance additives that assist in protecting gear teeth, a limited slip additive for optimal clutch pack performance, and an anti-foaming agent for better lubrication and service life. Great value and great quality.

[This review was collected as part of a promotion.] I have always been satisfied with valvoline products, and this was no exception. I used this product and the gears didn't have any issues. I will definitely buy this product again for my future needs.

[This review was collected as part of a promotion.] I ended up using this oil in the lower unit of my outboard. The squeeze bag made it easier to fill without needing a pump. This was just right product for the job. It's recommend giving the squeeze bag a try next time you're filling some gear oil.

[This review was collected as part of a promotion.] You cannot beat the quality of valvoline. The pouch container is just so convenient and makes it easier to get into all the little nooks and crannies. It lets you use all of the product as well instead of leaving some in the bottle. Works perfectly too.

[This review was collected as part of a promotion.] We usually do a lot of car maintenance at home including changing the car’s oil. This is a high quality oil and typically the brand I like to use for my vehicles. It keeps the car running smoothly and in good condition. One thing that stands out about this is the packaging. It makes filling up in tight spaces so much easier compared to the traditional packaging.

[This review was collected as part of a promotion.] Excellent product for transmission fluid. Easy to use, normally you have to get a pump and put a hose in the little hole and pump a bunch of it in and break your arm doing it, this one you just cut the tip, pop the seal and squeeze it, like toothpaste keep folding the tube over until oil starts to drip back out of the reservoir, works well what a great idea.

[This review was collected as part of a promotion.] The tip is perfect for precise application. I like that it’s a pouch so you can squeeze out exactly the amount you need of this Valvoline full synthetic gear oil. I like the thickness of the oil, seems like it will do the job well and last long.

[This review was collected as part of a promotion.] If you need a 75W-90 weight gear oil, you already know and trust Valvoline to make a good quality synthetic product. But the FlexFill bags really are a game changer. When going to fill gear oil into horizontal holes in inconvenient locations, such as transfer cases, you often need a fluid transfer pump to get the product in there. These bags remove that from the equation, allowing you to squeeze directly from the pouch. Make your life way easier and who doesn't love that?
