Renegade.
Race fuel thinking, by the bottle.
Fuel additives from a racing fuels company: an octane booster for petrol engines that run boost and timing, and a cetane booster that wakes up hard-working diesels. Simple bottles, blended by people whose day job is fuel itself.
Partner brand · Official UK distributorWhy we choose Renegade
Not every supplier makes the cut. Renegade is on the shelf because pump fuel varies more than people think, and a mapped engine notices. This is the additive shelf done by an actual fuel company.
Made by fuel people
Renegade's core business is racing fuel. The boosters are that chemistry packaged for the fuel you can actually buy.
For the tuned and the loaded
Octane headroom protects a mapped petrol engine at full send; cetane helps a working diesel light cleanly and pull smoothly.

Renegade questions, answered
Do I actually need an octane booster?
On a stock engine running the right pump fuel, usually not. On a tuned engine mapped near the knock limit, or when good fuel isn't available, the headroom is genuinely useful.
What does a cetane booster change on a diesel?
Higher cetane means the fuel lights more readily: smoother cold running, cleaner response and a happier engine under sustained load or towing.
Will these affect emissions equipment?
They're designed for engines with modern emissions hardware in place. Tell us your vehicle and we'll confirm suitability before you order.
What are lead times?
Bottles are small stock that moves quickly. We'll give you a real date before you commit, not after.
