Types of lubricatns
Long Life Fully Synthetic Engine Oil
A range of high specification engine oils formulated to meet and EXCEED the most stringent emission requirements of car manufacturers, including extended drain capabilities, for engines operating under long life variable service regimes, carrying full manufacturer approval where appropriate. Recommended for all modern cars, especially Euro IV or V and those fitted with the latest emissions control equipment such as diesel particulate filters (DPF).
Fully Synthetic Engine Oil
High performance car oil using the latest fully synthetic oil technology. A range of engine oils suitable for today’s high output engines. These fully synthetic oils save you money by offering improved fuel economy, significantly reduced engine wear and reduced oil consumption. Added benefits include lower engine drag, reducing friction releasing more power for faster acceleration and reduced emissions. Recommended for modern cars, especially high performance and turbo models.
Semi synthetic engine oils offer more protection for your engine than mineral oils, especially engines with hydraulic valve lifters during cold starts when engine wear is highest. Added benefits are lower engine drag, with faster acceleration and reduced oil consumption. Diesel specific semi synthetic oil also offers enhanced turbo protection.

API "S/C" SPECIFICATIONS, for petrol and diesel engines
API SPECIFICATIONS

These define three categories of lubricants identified by a two-letter code. The first distinguishes the engine for which it is intended: S means Service (petrol vehicles), C means Commercial (diesel vehicles), G for transmissions.
The second letter indicates the performance level: the further down the letter is in the alphabet, the higher the performance level. The latest specification for petrol vehicles is API SL while for diesel vehicles recently API specifications API CH-4 and CI-4 have been reached.
The tests required by the API, from SH onwards, are carried out following the rules of the CMA protocol (engine test control, formulation control, data control).
To obtain this classification, a lubricant must pass four engine tests, which consider:

- the increase of the engine oil temperature in service
- the lengthening of the interval between oil changes established by the manufacturers
- engine performance research
- strictness of environment protection standards
- reduction of fuel consumption due to low viscosity (only for "Energy conserving" oils)
API "S" SPECIFICATIONS, for petrol engines
- ​API SG For petrol engines of cars and light commercial vehicles starting from 1989. SG oils have better features than SF in terms of resistance to the formation of deposits, protection against wear and resistance to corrosion.
- API SH Same features as SG but more stringent test conditions.
- API SJ Engine oil of SH level, but developed in accordance with APY certification systems following multiple test criteria.
- API SL Born on July 2001, intruduces limits in terms of stability to oxidisation, deposit control at high temperatures, reduction of volatility and consumption rates.
- API SM Valid from November 2004, it asks for tougher tests about stability to oxidation, deposit control, performances at low temperatures.
API "S" SPECIFICATIONS, for petrol engines
- CF For diesel engines with indirect injection and for other diesel engines which use a broad range of lubricants, including those with a high sulphur content (over 0.5 wt.). Control on deposits on the pistons, wear and corrosion of the bearings is important for these engines, which may be naturally aspirated, turbo-charged and high performance turbo-charged. The oils for these functions began to exist in 1994 and can be used when specification CD is recommended.
- CF-2 Two-stroke diesel heavy-duty engines. Typical for two-stroke diesel engines, which require effective control on the cylinders, rings and deposits. The oils designated for this type of service began to exist in 1994 and can be used also when specification CD-II is recommended. They do not necessarily meet the requirements of specification CF or CF-4 even if they do have to pass these tests as well.
- CF-4 Diesel engines 1990. Typical high speed service, 4-stroke engines. It exceeds the requirements of specification CE, providing more control on oil consumption and deposits on pistons. These oils ought to be used instead of the oils in category CE. Ideal for long journeys and harsh conditions of use. When combined with the appropriate S category, they can also be used for petrol engines and light diesels (cars, light vehicles, vans) if recommended by the manufacturer.
