I was told years ago by a dealership serviceman the Detroit 2-53 should be run with a low sulfated ash content engine oil (<1% sulfated ash, if possible).
Most multigrade conventional 15W-40 Diesel oils I know of have higher ash content, 1.3% or greater.
The Chevron Delo 100 single grade 40W formulated for Detroit Diesel 2 cycle applications has 0.8% sulfated ash. This oil contains 0.096% phosphorous & 0.105% zinc according to the product data sheet. I would have expected these values to be higher (.12-.13%) for slider tappet/valve train longevity.
Is this what most folks use for 2-53 engine oil Delo 100 straight 40W?
