ACDelco GM Original Equipment 10-4108 Dexron 75W-90 Gear Oil – 32 oz

It was time to replace the fluid in my differential at 100K miles. I always want to use OEM products in my vehicle. It’s difficult to find this fluid locally. Fortunately there’s always Amazon. It took about a week to receive as of wasn’t fulfilled by Amazon. But I’m very pleased with this product.
