Chevron's Delo dropping conventional oils from heavy-duty diesel lineup
Chevron Lubricants will discontinue its popular Delo mineral-based conventional oils early next year from the Delo heavy-duty diesel engine lineup.

On this episode of The Dirt, we hear from Shawn Whitacre, a senior staff engineer at Chevron, who tells us why the shift and what it means for customers.

He explains that the move follows a trend toward synthetic oils. Its also designed to simplify the sometimes overwhelming number of choices customers face. Chevron has announced that these Delo oils will be discontinued starting January 15: 400 SDE 10W-30, 400 SDE 15W-40 and 400 XLE 15W-40. They will be replaced by Delo 400 XLE SB SAE 15W-40.
