Introduction to Total Products

What does it all mean?

Oil Grade

Product Category

Total Engine Oil Range (petrol/diesel)

Product Category

There are 3 different types of base oils which are used in lubricants

manufacturing process:

Mineral oils are made from petroleum-based products and undergo no

transformation.

Synthetic oils consist of chemicals compounds. Synthetic oils are

preferred to lubricants refined from petroleum when operating in extremes

of temperatures, as it provides superior mechanical and chemical

properties than those found in mineral oil.

Semi-synthetic oils which are blends of minerals and synthetic oils

(no more than 30%)

Engine Oil SAE Viscosity Classification

Viscosity grade provides information on oil viscosity when submitted

to temperatures variations. Multi-grade oil indicates a viscosity

grade at low and high temperatures.

EXAMPLE:

5W stands for viscosity grade at low temperatures.

W= Winter not weight

The lower the index is, the more fluid motor oil will be at low

temperatures, which ensures optimal lubrication when starting the

engine.

30 stands for viscosity grade at high temperatures.

The higher the grade is, the more viscous motor oil will be at high

temperatures, which enables better lubricating at high temperatures.

Starting Temp Summer Grade

The lower the winter grade, the lower temperature are accepted by the oil.

The higher the Summer Grade the higher the temperature the oil can accept (protect the engine at high temp).

Start up oil flow is very important!

International Specifications / OEMs

Total Lubricants meet international specifications as ACEA, API, JASO and ILSAC to ensure high technical performances.

In addition, some OEMs (Original Equipment Manufacturers) set up quality certifications to protect and optimize their engines' performances. These homologations are more stringent than international standards.

The OEMs recommend the use of specific motor oil requirements (see your car maintenance guide)

2. EGR Transfer Pipe (Hot)

3. EGR Cooler

4. EGR Transfer Pipe (Cool)

Source: Detroit Diesel

Impact on Lubricants:

High operating temperature;

EGR => more NOx & PM in oil => increase of nitro-oxidation & necessity of higher dispersant performance

EGR System (Exhaust Gas Recirculation)

Reduction of pollutant emissionsParticulate filter (DPF)

Particulate filter: Operating principle

Stage One: Filtration

Particulates accumulate in the silicon carbide filter medium.

Stage Two: Regeneration of the clogged filter

Combustion of accumulated particles in

the particulate filter.

DPF – Particulate Filter

CRT = DOC + DPF

DCO reduce CO & HC

DPF burns particulates

Require use of ULSD

( max 50ppm)

CRT® (Continuous Regenerating Technology)

Particulates Reduction of 30%

NOx Reduction of 80-90%

UREA = AdBlue (DIN 70070)

Use of approximately 5 - 6% UREA compared to fuel consumption

Reduction of fuel consumption by 4–8% reference to EURO III engines

Require a distribution networks for UREA (AdBlue)

The SCR System

Source: Johnson Matthey Website

SCRT® (Selective Catalytic Reduction Technology)

SCRT = CRT + SCR

CRT reduce CO,HC & PM & enhance low temp NOx reduction

SCR provides high temperature NOx reduction with in the presence of aq. urea

FE (Fuel Economy Lubricants)

Fuel Economy lubricants are designed to provide maximum protection to vehicles' engines and enable major savings.

TOTAL Fuel Economy range is used today in numerous types of vehicles (cars, heavy duty, etc.) and industrial machinery (agriculture, public works, etc.).
