FAQ's

Diesel Exhaust Fluid (DEF)

On average, 2.5 gallons (9.5L) of DEF lasts around 800 miles.

Typically, 1 gallon of DEF is required for every 50 gallons of diesel fuel consumed.

DEF usage may vary depending on the vehicle, engine load, and driving conditions.

The cost of TURBO BLUE DEF varies depending on the packaging and volume:

Bulk / 1000L IBC tanks → approx. ₹40–55 per litre

20L / 50L drums → approx. ₹60–80 per litre

Small packs (3–5L cans) → can cost ₹200+ per litre

Buying in larger quantities significantly reduces per-litre costs.
