APPLICATIONS
The goal of racing is to optimize the performance of a given machine for a specific race.
Hence, a single lubricant alone cannot possibly achieve top performance
for every engine type in every event. MOTUL MOTORSPORT, thanks to its
line-up of four different products, shall match every combination of
motors and races. Suit engines of any displacement, whether of recent
or past technology (Historic racing car type), multivalve, turbocharged
or atmospheric, carburettors as well as fuel-injection, using leaded or
unleaded gas, diesel-oil or liquefied gas, and catalytic exhausts.
For the most demanding uses of engines and lubricants:
* car racing
* sporty motoring
* long motorway journeys
* trips too short for a proper warm-up
* heavy hauls (trailers or caravans)
* city use (fuel washout during protracted idle, high running temperature for lack of engine cooling)
PERFORMANCE
Formulated upon esters and extremely efficient antifriction stocks, the
300V's are 100% SYNTHETIC and include no-or quite little (*)-viscosity
boosters to achieve an extraordinary high resistance to shear.
The common characteristics along the whole 300V line are :
* a remarkable decrease of the engines internal frictions, which
guarantees high performance and reliability, quite often topped with a
noticeable decrease of running noises
* a top resistance to high temperature charring - an extreme resistance of the oil film
* a low volatility, with quite little evaporation at high temperatures

SPECIFIC TESTS
Oil film resistance
Conventional multiple grade mineral and semi-synthetic motor oils, as
100% synthetic super-multigrade lubricants (5W40, 5W50, 20W60...) use
additives to boost their viscosity. These viscosity additives tend to
loose efficiency when submitted to extreme conditions, which translates
into a drop of viscosity and oil pressure.
Since the 300V's of the MOTUL MOTORSPORT line benefit from the natural
viscosity of synthetic ester basestocks, they need very little of such
additives, or none (*).
The ASTM D 4741 official test of HT/HS* (High Temperature High Shear)
viscosity measures the viscosity of lubricants at very high temperature
(150°C / 302°F) and shear (1 000 000 s-1). This test is considered to
be a good model of the fluid's state when exposed to extreme shear and
temperature as found in an engine.
The higher the benchmark, the best the oil film keeps up its viscosity,
hence its resistance to high stress in hydrodynamic rating. Tests prove
the best results are achieved with a high viscosity grade (50 or 60) at
high temperature, and without viscosity boosters.
Resistance to high temperature coking
While racing, when the engine is pushed to the extreme, or during pit
stops and refuellings, the oil temperature reaches maximal values.
Same happens to usual cars when stuck in traffic jams, hard or fast-driven for long journeys, or stopped at busy toll-gates.
Hence the capital attention to avoid the carbonization of lubricants
heated to high temperatures.The lubricant residues carbonized through
overheating (i.e. charring) are weighed, the best benchmark being a low
weight.
The test measures the coking of engine oils at a sustained high
temperature (5 days at 160°C / 320°F) and blasted for 48 hours against
an aluminum shim heated at 290°C / 554°F.
Tests prove the choice of basestocks, especially synthetic ester bases,
to be a major promoter of resistance to high temperature coking.
The 300V's of the MOTORSPORT line reveal virtually almost no coking during this test. Sold per 2 Litre
