The Problem
In Vietnam, motorbikes aren’t a luxury — they’re survival.
But of the 37 million bikes on the road, over 20 million are outdated and lack even the most basic engine warning systems.
Without an oil change light, millions of riders are unknowingly damaging their engines day by day — putting livelihoods and lives at risk.

Without an oil change light, millions of riders are unknowingly damaging their engines day by day — putting livelihoods and lives at risk.
And while innovation often chases the future, Vietnam needed a smarter solution for a problem rooted in the past.
The Insight
Motorbikes are essential — but their tech isn’t.
No dashboards. No sensors. No apps.
To truly make an impact, we needed a fix that was as accessible as it was ingenious.

The Story We Told
We went back to basics and engineered a small, elegant solution: the Castrol Oil Meter.
Using liquid pressure, this humble, low-cost device replaces the traditional dipstick with a visual indicator that moves up or down based on oil levels.
No batteries. No electronics. Just physics — applied with purpose.

When oil is running low, the red marker visibly drops, signaling the rider to top up — before damage kicks in.
With a simple upgrade, any old bike could tell you when it needed help — and Castrol became the brand that listened to both the engine and the people who rely on it.
The Outcome
The Oil Meter didn’t just solve a maintenance issue.
It became a symbol of practical innovation — engineering that respected the realities of daily life in Vietnam.
It protected engines, extended livelihoods, and positioned Castrol not as a brand that talks innovation, but one that builds it where it matters.

A campaign that proved progress doesn’t always mean moving forward...
sometimes, it means going smartly back.
