I bought and old truck. It has a large 855 cu in Cummins engine in it. Right now I'm just driving it from one side of the property where I keep it to the other side where I can work on it.
I don't know how long the engine oil has been in it so I want to change it and the filter just so I know.
Thge good stuff like Rotella, Delo etc are in the $9 a gallon range and the thing holds 11 gallons. These oils are Rated CI-4 plus.
The Coastal,ST and PepBoys Proline is in the $6 a galllon range and is rated CI-4 but no "Plus.
Am I wrong to think that fresh "cheap" oil is probly better than whats in it now?
