Question 1

ACEA Car Engine Oil Specification Explained

Accepted Answer

ACEA Spec is a very common sight, in fact you'll find one on almost all engine oil, but what does it all mean?

ACEA (European Automobile Manufacturers Association) have a system of rating oils, which you will find on the container of almost every oil on the market. These are the current specifications,previously oils were given separate petrol and diesel ratings, but from November 2004 onwards, those have been combined (A still refers to Petrol and B to Diesel engines). ACEA's Mission Statement is defined as:

Define and advocate the common interests, policies and positions of the European automobile industry;
Engage in dialogue with the European institutions and other stakeholders in order to advance understanding of industry-related issues, and to contribute to effective policy and legislation at both European and global levels;
Act as a portal for expert knowledge on vehicle-related regulation;
Communicate the role and importance of the industry, using reliable data and information;
Monitor activities that affect the automobile industry, cooperating with the other stakeholders involved; and Undertake strategic reflection on the increasingly global challenges of mobility, sustainability and competitiveness.

Question 3

Engine, Gear Oil & Grease Viscosity / Grade Classifications Explained

Accepted Answer

We explain the mechanics behind the different grade classifications of car / motorcycle oils & greases.

Viscosity Classifications INDUSTRIAL LUBRICANT CASSIFICATIONS

ISO (International Standards Organisation) viscosity classification. The ISO viscosity classification uses mm2/s (cSt) units and relates to viscosity at 40oC. It consists of a series of 18 viscosity brackets between 1.98 mm2/s and 1650 mm2/s, each of which is defined by a number. The numbers indicate to the nearest whole number, the mid points of their corresponding brackets. For example, ISO viscosity grade 32 relates to the viscosity bracket 28.8 to 35.2 mm2/s, the mid point of which is 32.0 mm2/s. This is illustrated in the table below, which shows the ISO viscosity grade numbers, the mid-points of each bracket, and the viscosity limits

This system is now used to classify all industrial lubricating oils where viscosity is an important criterion in the selection of the oil. Cutting oil and some other specialized products are more important in relation to grade selection.

Kinematic Viscosity at 40°C (mm 2⁄s) ISO Viscosity Grade (ISO VG) Minimum Maximum Mid-Point 2 1.98 2.42 2.20 3 2.88 3.52 3.20 5 4.14 5.06 4.60 7 6.12 7.48 6.80 10 9.0 11.0 10.0 15 13.5 16.5 15.0 22 19.8 24.2 22.0 32 28.8 35.2 32.0 46 41.4 50.6 46.0 68 61.2 74.8 68 100 90.0 110 100 150 135 165 150 220 198 242 220 320 288 352 320 460 414 506 460 680 612 748 680 1000 900 1100 1000 1500 1350 1650 1500 GREASE CLASSIFICATIONS

Question 6

API Car Gear Oil Specification Explained

Accepted Answer

API Spec is a very common sight, in fact you'll find one on almost all gear box oil, but what does it all mean?

The American Petroleum Institute (API) has a system of specifications for classifying gear and differential oils with a GL (Gear Lubricant) rating American Petroleum Institute (API) Gearbox Oil Specifications

Denotes lubricants intended for manual transmissions operating under such mild conditions that straight petroleum or refined petroleum oil may be used satisfactorily. Oxidation and rust inhibitors, defoamers, and pour depressants may be added to improve the characteristics of these lubricants. Friction modifiers and extreme pressure additives shall not be used. API GL-1 lubricants are generally not satisfactory for many passenger car manual transmissions. However, these lubricants have been used in some truck and tractor manual transmissions. Lubricants meeting service designation API MT-1 are an upgrade in performance over lubricants meeting API GL-1 and are preferred by major commercial vehicle manual transmission manufacturers. In all cases the transmission manufacture by major commercial vehicle manual transmission manufacturers.
