Mobil 1 Gear Oil, 75W90, Limited Slip Additive, Synthetic, 1 qt Bottle, Each

Good stuff ,enough to do whole drive train on a 1992 5 speed manual 4 runner

Very pleased so far. I had some unknown, burned-up 75w-140 (or possibly just really beat-up 75w-90) fluid in the front and rear diff's of my recently acquired 99 Subaru Impreza Outback Sport. The diff's were noisy and driveline drag was simply horrible. "Coasting" with my 4spd Auto was an abstract concept. My auto coasted like a manual...whiplash. I drained the old fluid (which smelled burned and was brown) and put this stuff in the front and rear differentials. Instantly, it seemed that even throttle response was heightened and the car could coast! This isn't to say that this is magic fluid, but only to show how horrible the previous fluid was. I'm very pleased so far. Truthfully, I'm planning on running this fluid for a few thousand miles (3-5k) and then draining this in favor of Lucas Syn 75w-90 with a hint of Redline Heavy Shockproof. I have a buddy who used that combo in his 2007 Tundra rear end and he said it not only saved his noisy diff, but reduced his diff housing temp by over 20 degrees on his commute home. That's huge. However, in the meantime, this is so cheap it's competitive with dino-based gear oils. In fact, at $11 shipped, there's simply no excuse to NOT use this as a baseline even on a beater. Bottom Line: My 99 Impreza OBS's differentials are quieter and run cooler. Further, the car coasts quite effortlessly now, as opposed to before with the old gear oil. I am confident that this would protect my differential for a std 50,000 change interval. For highway driving with AWD vehicles, there's no excuse to not be using a fully synthetic gear oil. Also, this 75w-90 also supplants the 80w-90 rated gear oil for the front diff in my 99 Subaru. It's meets the specs even though it's a lighter grade (because this is fully synthetic).

as advertised - it is gl5 although the picture doesn't show it anymore.

Works great

I've been using Mobil 1 products for over 30 years. The BEST. It has kept my vehicles running for VERY extended amounts of time. The key is "regular" maintenance. I do my own!

Great high-quality oil for your front and rear drivelines. Use it in my GMC Denali HD Duramax and my GMC Yukon Denali. You can't go wrong with Mobil 1. Good stuff!

good price since you don't have to buy limited slip additive.

Smooth Shifting, Reliable Protection Mobil 1 75W-90 synthetic gear oil has been an excellent addition to my maintenance routine. Right away I appreciated that it comes with the limited slip additive already blended in, so there’s no guesswork or need to buy something extra for differentials that require it. I used it on a rear differential service, and the difference was noticeable—smoother operation and quieter performance. The viscosity feels right in all conditions, with no whine on cold mornings and no thinning out when towing in the summer heat. Mobil 1 has always been a brand I trust, and this gear oil holds up to that reputation. The quart bottle is easy to handle and pour, and the synthetic formulation should give it a long service life between changes. Something to note: if you have a vehicle that doesn’t call for a limited slip additive, just confirm compatibility before use since this formula already has it included. Bottom line: A top-tier synthetic gear oil that delivers smooth shifts, strong protection, and peace of mind, especially for vehicles with limited slip differentials.

Item delivered on time, we'll done recommend

It's a great item

I use this to lube my Suzuki DRZ400’s chain, and it works better than any Chain lube out there. Way less noise and smooth as silk. Love it!

Delivery was quick, individually wrapped for leak prevention. As described, perfect for the differential oil change on my truck. Should last a very long time full synthetic. This already contains the Friction Modifier Additive if you have A limited slip as well. A+

Very good
