# Neglected black fluid vs fresh fluid

A cars format, measured November 8, 2026 by Volume. https://tryvolume.app/working/cars/neglected-black-fluid-vs-fresh-fluid

Open on a gross sludge or dirty fluid release and contrast it with the fresh, bright replacement. It worked for 3 accounts, with a median of 8x their usual reach. Type: Editing trick. Seen as: Video, Voiceover.

## Why it works

The high-contrast visual is satisfying and a little disgusting, which pulls in non-car viewers. The neglected-vs-new comparison also carries the wallet-pain warning.

## How to make it

1. Lead with the dirtiest fluid or buildup in the first seconds
2. Show the flush or cleaning in fast cuts
3. End on the bright fresh fluid or clean part

## How this is measured

- Every post is compared with its own account's usual reach, not with other accounts. "14x their usual" means the post got 14 times the median views of that account's recent posts.
- TikTok videos and Instagram Reels are measured on views. Instagram carousels have no view count, so they are measured on likes against the account's usual likes, and say so.
- A post makes the library at 2x its account's usual or more. A format is a repeatable move (what is said or shown, or how it is edited) that several accounts used in breakout posts. It is listed here once it worked for 3 or more different accounts.
- Formats rank on how many accounts they worked for and how far above usual, damped so a fluke on one tiny account cannot outrank a format that worked for ten.
