"Why are they selling 75W-110 when that viscosity is not even recommended in any of the manuals? 

In 2005, SAE changed their oil viscosity scales. 75W-90 was found to be too broad of a range and was split in half. The lower half remained 75W-90, the upper half became known as the new viscosity of 75W-110. All Montero manuals were published prior to this change, so what we call 75W-110 today, would have also been known as 75W-90 when the manuals were written.

"Should I get 75W-90 or 75W-110?" 

You can go with either, they're both in spec for all Montero and Montero Sports and the differences between them are minor. 75W-90 will have less drag so a slight edge in MPGs, and may be the better fit for the daily driver/occasional offroader. Whereas 75W-110 may be better for the purpose built offroad rig that spends a lot of time in 4 wheel drive, or is used for towing, because of the greater protection it offers at higher temps. 

75W-90

  • Most popular Red Line gear oil, with thousands of applications for passenger cars, light trucks and racing vehicles
  • Contains additional friction modifiers for suitability with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required
  • This product is not designed for use in most manual transmissions or transaxles in passenger vehicles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems
  • Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360 and Chrysler spec MS-9763
  • Suitable replacement for a differential calling for an 80W90 or SAE 90 gear oil

Red Line products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation

  • Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
  • Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
  • High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
  • Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
  • Exceeds API GL-5 specifications
  • Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear

NOTE - Red Line quart bottles have a narrow neck and will not work with traditional fluid hand pumps. We use this syringe style pump and it works great.
