2 • Methanol
Produced to the highest standards,
its purity exceeds 99.85%.
Methanol’s high-octane value and
oxygen content (50%) make it prime
choice where maximum power is
required and where regulations
permit its use. It also burns very cool
with a colourless flame, helping
to control engine temperatures.
Recommended for use with nonperishable fuel lines.
25 Litre drum
(RMETHANOL-25) £67.25
3 • R6SR
102 RON, leaded fuel developed
for engines that still require lead to
lubricate the valves and valve seats.
Provides protection against knock
for compression ratios up to 13:1.
It is completely ethanol free making
it a good choice for classic or
historic applications.
25 Litre drum (R6SR-25) £108.25
4 • CFR
102 RON Unleaded race fuel that
conforms to FIA appendix J and the
MUK blue book section B definition.
Provides knock protection up
to compression ratios of 12.5:1.
Blended with 2.2% oxygen allowing
a more complete burn resulting in
more power.
25 Litre drum (CFR-25) £103.25
5 • CMR
100 RON Unleaded race fuel that
conforms to the MUK blue book,
meeting the requirements of
BS7800 and BSEN228. Compliant
also for FIM, FIA and CIK events.
Blended to give more consistent
performance than can be achieved
with regular pump fuels
25 Litre drum (CMR-25) £98.25
10 • CFS Storage Plus
Race Fuel
1 • S70LE8
102 RON, is an oxygenated high-octane, leaded race fuel designed for
historic racing. It contains 70% sustainable components and offers excellent
valve seat and detonation protection for engines that require leaded fuel
whilst ensuring engines run smoothly and efficiently.
25 Litre
(S70LE8)
£158.25
6 • Supreme
115 RON, Nil oxygen leaded,
designed for sophisticated high
compression engines which
routinely function between
7,000 - 10,000 rpm. Suitable for
compression ratios up to 15:1.
Excellent fuel to mix with unleaded
pump fuel, to produce a cost
effective race fuel.
25 Litre drum (SUP-25) £145.25
7 • E85R
The E85R consistently contains
85% ethanol and 15% selected high
quality, powerful hydrocarbons
typically used in their race fuels.
Offering far more consistency over
pump E85 which can range from 6879% with varying blends.
25 Litre drum
(E85R) £93.75
£39.00
8 • FR
102 RON A high quality unleaded
E10 race fuel. Blended with an
elevated level of oxygen enabling
a richer mixture for more rapid
engine response. This also helps
where engines must run restrictor
plates. FR provides protection
against detonation to compression
ratios as high as 12.5:1. MUK and
FIA compliant.
25 Litre drum (FR-25) £120.75
9 • 260 GT Plus
110 RON, 4.7% oxygen unleaded,
perfect for track day and highly
tuned engines, particularly turbo
applications running high boost.
Can be used with compression
ratios up to 15:1.
25 Litre drum (GTP-25) £140.25
FUEL TRANSFER
An ethanol free unleaded petrol
which is capable of being stored for
up to 3 years. Perfect for vehicles
which do not get used regularly,
especially classics with rubber
fuel hose and other fuel system
components which can be degraded
by ethanol. Storage plus burns
extremely cleanly and has a 99
RON octane, so is ideal for high
compression or forced induction
engines.
10 Litre (STORAGEPLUS) £39.00

11 • CFS Storage 5 Star
Race Fuel
An ethanol free 103 RON leaded
version of the storage plus. Designed
especially for vehicles where
hardened valve seats have not been
fitted to provide protection from
valve seat recession.

12 • High Flow Rotary
Hand Pump
13 • Torco
Unleaded Accelerator
This rotary hand pump is suitable
for use with 205 litre drums and
can deliver up to 100 litres per
minute with ease via the use of
twin rotor technology. The body is constructed from lightweight
aluminium with a steel rotor and riser. The spout, which can be removed,
has an outside diameter of 32mm. A 2" BSP bung adaptor allows the pump
to be fitted onto the most common types of steel drums. Suitable for use
with petrol, methanol and low viscosity oils.
Pump Type: Rotary Vane, Flow - 100 litre/min (approx.)
Maximum Fluid Temperature:
60°C, Bung Adaptor - 2" BSP Male
Suction Tube Length:
101cm, (39.7”) Inlet - 1-1/4” OD, Outlet - 1-1/4” OD
Maximum Viscosity: 1000mPas

Torco’s Unleaded Accelerator is race
fuel concentrate. While possessing
many of the same additives as full
race fuel, Unleaded Accelerator
uses a blend of components that
will transform regular fuel from
the pump to closely resemble race
fuel. It also reduces the end burn
temperature which enables fuel to
burn more effectively thus provided
better combustion and ultimately
more power from the engine. Used
at a ratio 20:1 it will provide a rating
of 105 from regular unleaded.

14 • Silkolene
Pro Boost Octane Booster
A high performance octane improver
that is also designed to prevent preignition or “knocking”. Due to its’
unique lead-free formula, it enhances
combustion, reduces upper cylinder
wear and burns cleanly without leaving
deposits in the combustion chamber.
Throttle response is improved and
helps to reduce heavy exhaust gas
pollution when the engine is cold. Pro
Boost is also compatible with all forms
of petrol and does not harm fuel hoses
or filters. Available in a 1 litre bottle,
mix at 1-3% of the total fuel for the best
results.
1 Litre
(602014818) £21.50
15 • Alky Methanol/
Ethanol Additive
Specifically designed for use
with ethanol and methanol fuels.
Reduces corrosive properties of
the fuels and reduces bore wash.
Also causes Methanol to burn with
a yellow flame, increasing safety
in the event of a fire, with such an
additive now being mandatory for
methanol fuelled cars in many
MSUK Speed events. One 222ml
bottle treats a 205-litre drum of
methanol.
