Additives
What it mixes with, decided first.

The range
An additive is only as safe as the system it goes into, so this range of twelve is organised by what it mixes with: engine oil, petrol, diesel or coolant.
Engine oil treatments boost, protect, flush and stop leaks, and the ENGINE PROTECTOR states plainly that it is not for low or mid-SAPS oils. Petrol treatments raise octane and clean injectors and intake valves. Diesel treatments improve cetane, keep fuel flowing in winter at two dosing strengths, reduce smoke and help a particulate filter regenerate. A coolant treatment seals small leaks. Each 250 ml bottle states its treatment rate, and one bottle treats one fill, so there is no dosing to work out on the forecourt.
- Engine oil: booster, protector, flush, leak preventer
- Fuel: octane, cetane, cold flow and DPF cleaner
- ENGINE PROTECTOR is not for low or mid-SAPS oils
Product lines

Engine oil
Oil treatments that boost lubrication and viscosity, protect high-mileage engines, condition seals against minor leaks and flush sludge from the oil circuit.
See Engine oil
Petrol
OCTANE BOOSTER raises RON by 3 numbers and cleans injectors; GASOLINE PERFORMANCE IMPROVER cleans the whole fuel system for complete, cleaner combustion.
See Petrol
Diesel
Cetane improvement for easier starts, injector cleaning with smoke reduction, and cold flow protection against wax crystals and gelling in winter, also as DIESEL COLD FLOW IMPROVER 1:500.
See Diesel- [Render to come]
Coolant
RADIATOR LEAK PROTECTOR for leaks in the coolant system.
