Most will say 10w30w but I think if its really high on miles you can use 20w50w in the southern regions of the USA or a oil made for high mileage engines. I have use 20w50 in all my 4cyl engines even when new, I live in the south.
thats right use mobile 1 high milage oil ! High mileage oils Motor oils formulated especially for vehicles with more than 75,000 miles
Mobil 1 is my 1st choice. Before synthetic I used Castrol oil.
I would use 5w30 Motorcraft synthetic blend as the manufacturer recommends.
2006 2.3L ford ranger with254,00miles which type of oil I should use?high miles oil or5w20
High mileage oil is fine to use, if its smoking/using oil use a thicker oil. 5w20 is what Ford calls for. If consumption oil loss is a issue with your mileage now try using 5w20 high mileage first, if oil loss continues try 10w30 high mileage.
