Grease Analysis

Grease Analysis Service

Our Grease Analysis service tests your grease for: levels of contamination, system wear and its chemical make-up. These tests (detailed below) are performed in laboratory conditions and the findings, along with any recommendations or required actions, will be returned to you in a comprehensive report.

The FA-ST Complete (UK) Grease Analysis & Sampling Kit (GKIT1) - featured below - is perfect for use to submit your grease samples to us. The kit can be used with all grease samples, comes with a pre-paid Jiffy bag and return address label, and is inclusive of the laboratory grease analysis service.

Please note the pre-paid Jiffy bag and return address label are not included in our International Grease Analysis & Sampling Kit (GKITOMK).

Grease Analysis Tests Performed

Contamination Testing

Contamination testing is split into a number of different individual test. We will perform:

Water K.Fischer

The Karl Fischer test measures the exact amount of free and dissolved water molecules contained in the grease sample. The Karl Fisher test is reported in a numerical value.

Boron Testing

Used as a corrosion inhibiter, anti-wear and anti-oxidant additive. Concentration levels vary greatly depending on grease brand. Also Boron is used in extreme pressure compounds and dispersants. It can also appear as a contaminant as it can be used in the manufacture of coolant conditioners. Boron can come from a few areas; it can come in with water, coolant, from worn seals or airborne dust.

Silicon Testing

Silicon is usually seen as an indication of dirt entry however it can have many different sources. Silicon is part of a chemical added to oils to stop them foaming so silicon can be an additive. It is usually found in a concentration of 5 to 10 ppm, so do not be surprised to see silicon in new engine oil samples. Do not panic, this is not due to dirt. Silicon is found in chemicals used in coolant conditioners so it can show up as a contaminant if there is an internal coolant leak, along with sodium.

Sodium Testing

The most common chemicals contain sodium so this is the first indication of an internal coolant leak. Other chemicals found in coolant conditioners contain elements such as molybdenum, phosphorus, chromium, boron and silicon. Elements that make up the physical structure of the cooling system and can leach into the oil (from either the water or the oil side of the cooler) include copper, tin, lead and silver. Sodium can also be found as an additive in some engine oils (often replacing calcium or magnesium) but this is a lot rarer than it used to be. Some greases contain sodium as part of the soap and sodium will be evident if the oil is contaminated with sea water.

Chemistry Testing

Testing for Calcium, Magnesium, Molybdenum, Phosphorus, Zinc and Manganese to check the level of additives within the grease to make sure that they are in spec.

System Ware Testing

A large range of different metals could be present in your grease: Aluminium, Chromium, Copper, Iron, Lead, Nickel, Silver, Tin, Vanadium and Titanium can all be tested for and the results from this test will allow you to see if any engine components are wearing.

Also the Ferrous Wear Index gives an indication of the total measure of Iron (regardless of size) in the sample. This technique is used to determine early component wear.
