It’s the small details that can sometimes really trip you up. In the case of a technician who was changing the oil on a Cadillac Escalade, he realized in real time that AutoZone sent him two different types of oil.
For TikTok creator Perri’s Mechanics (@perris.mechanics), an answer about the advisability of this maneuver is possibly found in his video’s comment section. After he’s poured five quarts of Mobile 0W-20 oil into his tank, from a five quart bottle, he grabs the next bottle. It’s smaller, and instead of yellow oil, the liquid is green.
Can You Mix Different Types of Oil?
“So, I guess there’s green oil, bruh,” Perri says as he turns a quart container marked 0W-20 toward the screen. But this smaller container has a slightly different label. In the lower right hand corner there’s a designation, “dexos-D,” it reads.
The Mobil 1 diesel oil is green: this is a deliberate design choice. The green tint is achieved when a blue dye is introduced to the yellow oil. It’s added to make it possible to safely trace fluid movement. Though some suggest there’s also a quality-control component: to prevent oil techs from adding a lesser oil.
