Millers oil is the best oil money can buy.

Competition full synthetic engine oil.
Formulated with 100% synthetic base fluids, including a synergistic blend of three esters combined with latest additive technology for maximum performance.

• Full synthetic oils provide many outstanding performance benefits over conventional mineral oils.
• By utilising both polyalphaolefins (PAO) and ester synthetics specially selected to minimise the amount of polymer used, the lubricant film provided is more resistant to ‘shear’ and viscosity loss in highly stressed areas.
Full synthetic oil provides:
• Load carrying capacity many times that of mineral oil.
• High film strength for ultimate protection.
• Outstanding cold flow properties for reduced wear at start up.
• Excellent thermal stability and oxidation resistance.
• The incorporation of a synergistic blend of three esters gives improved lubricity, reduced friction, enhancing the oils performance.
• CFS 15w60 is formulated to protect larger competition engines operating under extreme conditions e.g. long distance racing, rallying in both normally aspirated and turbo-charged engines.

I've used this in my own car now for 10 years with zero bearing failures.

Classis 20w50
Mineral based engine oil for classic engines.
* High quality solvent refined base oils with latest technology performance additives and shear stable viscosity index improver.

APPLICATION:
Use as received for engine lubrication of primarily pre-1980 vehicles, both petrol and diesel, which were developed on the multigrade oils of their time.

USER BENEFITS:
• Incorporates modern additive technology with period viscometrics to provide the optimum lubrication characteristics for engines manufactured in the immediate post war period through to the early 1980’s.
• Suitable for higher mileage applications where oil consumption is a problem.
• The modern technology ensures an oil which will meet the ‘period’ performance requirements along with up-to-date specifications

CVL Turbo
DESCRIPTION:
Octane booster and combustion enhancer based on advanced manganese chemistry.

APPLICATION:
Use as received, 1 bottle [500 mls] to 20 litres [maximum] unleaded petrol for all motorsport applications.
Precise treatment levels should be determined by test bed experimentation.

USER BENEFITS:
• Use with modern fuels to increase octane levels by up to 4 octane numbers (40 points).
• Provides improved performance for race, rally or track day.
• Provides similar flame front control as lead, thereby enabling engines to run more advanced ignition timing without danger of pre-ignition or detonation.
• Mixes with leaded, unleaded, LRP and other fuels containing octane enhancing additives such as oxygenates, ethanol and MTBE.
• Equally effective in modern engines fitted with knock sensors and catalytic convertors.

I've used most so called Octane boosters on my engine dyno and rolling road this is the only one which I have found to make any performace gains.
I use this in my own and all my pump gas engine, the reason is it works

Extra Cool
DESCRIPTION:
Concentrate multi-metal corrosion inhibitor and coolant enhancer.

APPLICATION:
Dilute with water in the ratio 1 part Extra Cool to 50 parts water [2% solution] for corrosion inhibition of vehicle cooling systems and deposit reduction.

USER BENEFITS:
• Helps to maintain coolant flow in radiators.
• Reduces deposit formation in radiators.
• Provides powerful corrosion protection for all metals found in engines e.g. aluminium, cast iron, etc.
• Helps reduce coolant temperature by up to 15 degrees.

PERFORMANCE PROFILE:
• Reduces engine damage from internal coolant leaks.
• Mixes with all good quality antifreezes.
• Does not provide antifreeze protection.
• Note: Antifreeze is often based on ethylene or propylene glycol, which are insoluble in oil. Internal coolant leaks may cause damage to highly stressed bearings.
