Ford Explorer uses the original 5W-40 specification oil. All Explorer models are equipped with turbocharged engines, and it is recommended to use full synthetic oil with a viscosity of 40. Generally, turbocharged engines use oil with a viscosity of 40 because the turbocharger also relies on oil for lubrication and heat dissipation. The details of Ford Explorer's dedicated oil are as follows: Oil viscosity: The viscosity of the oil should not be too high or too low. If the viscosity is too high, it will increase the resistance during engine operation, affecting the engine's power output and fuel economy. If the oil viscosity is too low, it will prevent the oil from forming a stable oil film on various components, which will increase engine wear. Replacement conditions: After adding new oil, sludge and carbon deposits on the components disperse into the oil, causing the oil color to turn black after a certain period. Usually, the oil's viscosity is used to determine whether it needs to be replaced, rather than observing the oil color turning black to conclude that a replacement is needed.

I've been driving my Ford Explorer for nearly a decade, always using 5W-30 synthetic oil. Ford officially recommends this grade because it offers moderate viscosity, ensuring smooth cold starts without thinning out in summer heat. My Explorer with the 3.0L engine specifies 5W-30 as standard in the manual. Regular oil changes are crucial – I check oil levels every 5,000 km, ensuring the dipstick (cold engine) never drops below MIN. Engine oil is the lifeblood; wrong viscosity accelerates wear and increases fuel consumption. Pairing synthetic brands like Mobil during maintenance extends service life. Even in northern winters, 5W-30 never froze. Always consult your owner's manual – it's foolproof against oil-related issues. With proper oil, my Explorer's clocked 300,000 km without major repairs.

I bought the new Explorer last year, and the manual specifies 0W-20 synthetic oil. Young people pursue fuel efficiency and environmental protection. 0W-20 has good low-temperature fluidity, allowing you to drive right after ignition, reducing city commuting fuel consumption by five percent. Ford designed this engine with 0W-20 to balance efficiency and protection. Maintenance is convenient—I use Shell or Castrol synthetic oil, pour in a full bottle, and replace the filter together. Checking the oil level is simple: park the car and wait five minutes for it to cool before checking the dipstick—don’t wait until the warning light comes on. Driving the Explorer in the South with more hot days, 0W-20 performs stably, keeping the engine quiet. Follow the manual’s instructions and avoid mixing different oil grades, as it can affect fuel efficiency. Proper car maintenance makes driving easier and saves money.

Having serviced countless Ford vehicles, the Explorer typically uses 5W-30 or 0W-20 synthetic oil. The 2.3L smaller engine is mostly paired with 0W-20, while the 3.0L larger variant opts for 5W-30. Always check the maintenance page of the user manual to confirm the correct type—don’t rely on memory. Synthetic oil resists high temperatures and prevents wear; using the wrong type may cause engine seizure. Monitor oil levels every change cycle, and top up promptly if the level drops below the 'min' mark. A simple check: feel the dipstick—if it’s dirty or black, it’s time for a change. Maintaining an Explorer isn’t complicated; using a reputable shop for oil changes ensures peace of mind. Pay attention to unusual noises while driving daily, as odd sounds may indicate oil-related issues.

My neighbor Brother Zhang uses 5W-30 synthetic oil for his Ford Explorer, the standard Ford specification. I've helped him change it a few times, and the steps are simple: check the oil level with the dipstick when the engine is cold, aiming for the mid-range mark. Add the same type of oil without exceeding the MAX line, and I recommend Mobil or Ford OEM oil. Summers in the south are hot, but 5W-30 viscosity is sufficient to protect the engine. Remember to check the oil level every three months, and if the oil light comes on while driving, pull over immediately. Spending a little on maintenance ensures the Explorer runs smoothly for years without issues. Using quality oil for your own car means a worry-free and stable ride.
