Don’t out DEF in your fuel. #duramax #fail #DEF #gmtech #dieseltechnician

2025/1/11 Edited to

Putting DEF (Diesel Exhaust Fluid) in your fuel tank can cause serious damage to your vehicle’s engine, leading to costly repairs. DEF is designed for post-combustion treatment, not for fuel injection. If your diesel engine is smoking, like in the case of the '2500 HD', it could be signaling severe issues. When DEF is mistakenly introduced into the fuel system, it can lead to fuel system failures and clog filters, rendering your vehicle inoperable. This blunder can cost you thousands in repairs. To protect your engine, it’s crucial to understand the distinct differences between diesel and DEF usage. Furthermore, if faced with this mistake, seek immediate assistance from a certified diesel technician to mitigate further damage. Knowledge about proper fuel practices can prevent expensive mistakes like this one in the future.

I think making your notes too cute is a mistake

A baby in a pink outfit is bottle-fed by an adult hand, with the title "My Biggest Mistake with pumping" overlaid. The image introduces the topic of the post.

An open cooler bag contains multiple labeled bottles and syringes filled with pumped breast milk. Overlay text explains reasons for pumping, including the author's NICU baby.

A hand holds a jar of pumped breast milk, accompanied by text detailing the author's mistake of overpumping, which led to overproduction and mastitis.

MY BIGGEST MISTAKE WITH PUMPING 🍼

I would like to start off by saying that I absolutely loved my lactation consultants I had at the hospital where I had my daughter! That said, I really wish they wouldn’t have said to pump until the milk stops coming out and wish they would have just told me the 15-20 minutes part. Maybe I shou

A woman in pink activewear performs a glute exercise with dumbbells, stepping on a box. Text overlays suggest she accidentally discovered a glute-lifting move that's now popular, with a search bar graphic at the bottom.

A man, identified as Bret Contreras, the inventor of hip thrusts, is shown in a video frame. Text explains an exercise called "Ballerina Bulgarians" was misnamed and publicly exposed by him.
