Dot 5.1 brake fluid

LONG LIFE 100% synthetic fluid for hydraulic actuated-brake and clutch systems.
DOT 5.1 NON-SILICONE BASE.
Fluidity specially designed for anti-locking brake systems.

LONG LIFE FORMULA : the high wet boiling point (185°c/365°F), superior to DOT 4 and DOT 3 fluids enables to use this product longer.
SPECIALLY DESIGNED TO ANTI-LOCKING BRAKE SYSTEM (ABS) : its viscosity (820 centipoises at -40°c / -40°F) lower than DOT 4 and DOT 3 brake fluids, allows MOTUL BRAKE FLUID DOT 5.1 an easier fluid circulation in micro-valves of anti-locking systems.
PERFECTLY NEUTRAL WITH SEALS USED IN BRAKING SYSTEMS. ANTI-CORROSION.

STANDARDS : FMVSS 116 DOT 5.1 NON SILICONE BASE & DOT 4 & DOT 3
SAE J 1703

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 - résistance très élevée du film d’huile
- 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, 10W60...) 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.


In can recommenr any of these products with usage in the RS4

Hi John,

Is this Motul engine oil "officially" approved by Audi/VAG?

No..but who gives **** [img]images/graemlins/grin.gif[/img]
Its the best on the market

JR,

The VERY best of all Motul oils is the V300 COMPETITION 15-50. No need to bother with others.

Can only endorse the brake fluid. Unlike most others (including other 5.1 ones) this makes the brakes feel more surefooted and with a better feel through the pedal even at leisurely exploitation.

Well presented post, btw.

Do you use this then JR?
