El embalaje fácilita la aplicación del aceite al diferencial, el aceite se ve muy bien en tonalidad y viscosidad. Además ya le hacia falta el cambio a mi unidad.

I've been using Valvoline Daily Protection 80W-90 Gear Oil in my 2016 Lexus IS300 for a few thousand miles now, and I couldn’t be happier. Ever since the oil change, my transmission feels smoother, shifts are crisp, and there's no noise or hesitation — even under hard driving. This gear oil offers excellent protection for daily driving and handles heat well, which is important for my IS300’s performance. It’s affordable, easy to find, and performs just as well as more expensive options. I appreciate that it helps keep my car running like new without breaking the bank. If you own a Lexus, Toyota, or any vehicle that requires 80W-90 gear oil, I highly recommend giving this a try. Solid product for long-term reliability and performance!

Valvoline is great rear-end fluid for my Ford 8.8. Added during a recent fluid and differential cover change. WIth the limited slip additive and Flexfill gear oil, my differential hooks up much better and is definitely smooth as butter. The gear oil bags/packaging are very useful but I still used a hand pump/hose to add back the new oil to the differential. Highly recommended for the health of your differential!
