For a 2004 Ford Explorer, the rear differential will require 75w140 gear oil. It will need 1.75 quarts, so you'll need to buy either a two-quart bottle or two one-quart bottles. The price for a single quart can range from $12 to $25, depending on the brand and store. Investing a bit more in a high-quality brand is advisable to prolong your vehicle's lifespan, making it a worthwhile expense in the long run.
Example: To illustrate, for residents of colder states like Minnesota, it is recommended to utilize a viscosity rating of 85w140, whereas for those residing in warmer regions like Texas, a viscosity rating of 75w140 is more suitable. This approach offers a clear distinction.
Can you explain the contrast between sae 85-140?
The 75w140 is the ideal rear differential fluid for a 2004 Ford Explorer according to the manufacturer's recommendations.
