Here's why:
* Specifics Matter: The correct oil depends on the specific rear differential your CRV has. There might be variations within the 1999 model year.
* Manual is Key: The best and safest information comes from your owner's manual. It will list the recommended oil type and specifications for your specific vehicle.
* Dealer or Mechanic: If you don't have your owner's manual, a Honda dealership or a trusted mechanic can quickly tell you the correct oil to use.
General Tips:
* Don't Use Regular Motor Oil: Rear differentials need a specialized gear oil that can handle the high loads and stresses.
* Check Viscosity: The recommended viscosity (like 75W-90) is crucial. Using the wrong viscosity can harm your differential.
Remember, checking the owner's manual or consulting a professional is the only way to ensure you're using the right oil for your 1999 CRV's rear differential.
