Titolo: Olio Castrol x diesel (Opel?) x Uoscar e altri...

Caro Uoscar,
ho trovato questo articolo sugli olii Castrol GTD. Tu quale usi in
particolare? A quanto pare il "Magnatec" e' specifico per proteggere il
motore durante la partenza a freddo:
"DIESEL DRIVERS TURN ON TO START-UP ENGINE PROTECTION
WITH CASTROL’S NEW LUBRICANT RANGE
Castrol’s tried and tested ‘Magnatec’ start-up protection now
available for diesel engines
With 75% of all engine wear caused by metal to metal contact on start-
up, Castrol’s new GTD Magnatec lubricant offers start-up and continuous
protection benefits to diesel engines - previously only available to
petrol engines.
Formulated to meet the needs of today’s diesel engines that combine
fuel economy with the power and performance to match petrol engines,
Castrol GTD Magnatec is one of two new diesel engine oils launched by
the lubrication specialists following extensive research into the
growth and requirements of the diesel market.
Also new to Castrol’s diesel range is the ‘soot-busting’ and fuel
efficient Castrol GTD Plus. This unique formulation joins Castrol GTD
Magnatec and the existing, mineral-based Castrol RX Super Diesel to
make a family of three products - each with features and benefits
clearly marked on the pack for ease of selection.
Castrol GTD Magnatec
Proven to offer the best wear protection, Castrol GTD Magnatec contains
unique polarised molecules that cling to an engine, even when cold,
protecting from the moment the ignition key is turned - unlike
conventional oils which only work fully when the engine has warmed up
and the oil has circulated completely.
Like Castrol GTD Plus, Castrol GTD Magnatec also disperses soot
particles, preventing harmful deposits from forming, and damaging the
engine.
Castrol GTD Plus
Building on the formulation of the market-leading Castrol GTD, this
lubricant has now been improved to become Castrol GTD Plus which offers
four times better viscosity control than conventional 15W-40 diesel
lubricants and is specifically developed to maintain fuel efficiency
and performance.
Formulated with unique hydrocarbon polymers - designed to hold in
suspension soot, dirt and acid caused by the by-products of engine
combustion - Castrol GTD Plus keeps oil at the correct thickness,
unlike conventional diesel oils which tend to thicken over time. By
dispersing dirt and soot and ensuring the oil ‘stays in grade’, Castrol
GTD Plus maintains optimum fuel efficiency.
Says Castrol’s technical director, Stewart Arklay, "Diesel cars now
represent 12% of the total UK cars on the road (Source: DoT Annual
Transport Statistics 1999) and 16% in Ireland (Source: Vehicle
Registration Unit, Shannon), and our research shows this figure is
growing steadily as more and more drivers come round to the fuel
economy, durability, environmental and long term reliability benefits
of a diesel engine.
"Castrol’s new range of technically superior lubricants is designed,
formulated and tested at the company’s in-house research and
development facilities at Pangbourne, Berkshire. Castrol scientists and
engineers have devised new diesel lubricant technology to combat
specific diesel engine problems such as metal to metal contact and the
control of dirt, soot and acid - with the aim of maximising diesel
engine performance," he added.
Castrol GTD Magnatec, Castrol GTD Plus and Castrol RX Super Diesel are
available now from motor accessory stockists.

io ho smesso di utilizzarlo quasi un anno fa, in favore del Mobil1 5W50
che uso tuttora (ma forse passero' al selenia racing 10W-60)...
allora la Castrol aveva appena rimarchiato il vecchio C888 come GTD, in
sostanza gli olii erano =, era cambiata solo la scritta. probabilmente
hanno differenziato i prodotti dopo la mia scelta di passare al Mobil1.
cmq quello che si "accosta" di piu' imho e' il plus, anche se
sicuramente sara' un'altra riformulazione... cmq la gradazione era
quella, 15W40, e sicuramnete non c'era il "funzionamento" magnatech...
CiAoOo!!!
