We’ve already discussed the benefits of Motul synthetic engine oils with our look into the H-Tech 100 Plus range, so now it’s time to delve a little bit deeper into the science of engine oils with Motul’s 8100 100% synthetic engine oil range.
If you aren’t familiar with the terms SAPS or HTHS, SAPS stands for Sulphated Ash, Phosphorus and Sulphur and HTHS stands for High Temperature High Shear.
A low SAPS engine oil is an oil with low sulphated ash, phosphorus and sulphur content. These engine oils have low ash formation, and are specifically formulated for petrol engines with 3-way catalytic converters as well as diesel engines with Diesel Particulate Filters (DPF). This is because when engine oil burns, the resulting particles accumulate in fine pores or vanes of the particulate filter or catalytic converter, plugging it and dramatically decreasing their lifetime. Phosphorus and sulphur are also particularly harmful to catalytic converters, as they prevent the catalyst from removing the toxic substances from the exhaust gases.
The thing is, additives like phosphorus and sulphur have generally been seen as necessities to providing high wear protection and maintaining engine cleanliness. But because of their effects to catalytic converters and DPFs, the amount of additives were significantly reduced. However, it is still necessary to develop entirely new additives for greater oil change intervals, less friction and adequate wear protection.
New additives are being developed every year to replace SAPS and provide and environmentally-friendly engine oils whilst retaining the great characteristics these additives offer for your engine, and Motul is right at the forefront.
HTHS viscosity is a dimensionless parameter related to the fuel economy and durability of your engine. While HTHS viscosity is related to absolute viscosity, it isn’t the same. HTHS viscosity is a measure of how well an engine oil protects during tough operating conditions, and influences factors such as fuel consumption and engine wear. Lower HTHS viscosity values (2.9-3.5) can improve fuel economy by reducing the amount of power required to pump it, but higher HTHS viscosity values (≥ 3.5) provide better protection for your engine. Therefore a careful balance should be considered when choosing which oil to use.
ASTM D4683 is the test method used to determine the HTHS value, simulating the conditions in an engine where temperatures and friction is the greatest. This is done via a Tapered Bearing Simulator Viscometer at an oil temperature of 150°C, but in practice, the oil must be thick enough for proper lubrication and thin enough to not leech too much power from your engine.
Why is this important you might be asking?! To answer simply, this is all in an effort to reduce emissions and improve fuel economy. In Australia, the guidelines for this are set-out in the Euro Emissions Standards. Here’s a quick overview:

Motul 8100 Eco-nergy 5W-30 (http://clixtrac.com/goto/?182352) is a full SAPS, low HTHS engine oil specially designed for modern engines requiring use of a low HTHS viscosity oil with ACEA A1/B1 or A5/B5 standards, and is compatible with catalytic converters. It contains specific friction modifier molecules that provide superior oil film resistance, maintain oil pressure and decrease engine operating temperatures. Eco-nergy 5W-30 also possesses outstanding lubricating properties such as wear protection and high temperature resistance for better controlled oil consumption with up to 10% better fuel economy during start-ups and short trips compared to a 15W-40 grade engine oil. Environmentally-friendly, it reduces fuel consumption and thus minimises greenhouse gas emissions. Motul Eco-nergy 5W-30 can be mixed with Motul synthetic or conventional engine oils.

Motul 8100 Eco-clean+ 5W-30 (http://clixtrac.com/goto/?182350) is a low SAPS, low HTHS lubricant for petrol or turbo diesel direct-injected engines. It has been designed for vehicles with the latest EURO emission regulations compliance, and require an ACEA C1 engine oil. ACEA C1 lubricants are environmentally-friendly, reduce fuel consumption as well as greenhouse gas emissions and also achieve extended drain intervals. Motul 8100 Eco-clean+ 5W-30 is compatible with catalytic converters and DPFs.

Motul 8100 X-max 0W-40 (http://clixtrac.com/goto/?182357) is a full SAPS, high HTHS high performance engine oil for modern high performance petrol or diesel engines, and is suitable for all types of fuels and with catalytic converters. The 0W-40 viscosity grade minimises hydrodynamic friction, and offers the perfect balance between fuel economy and lubrication performance. X-max 0W-40 meets the ACEA A3/B4 standards in order to improve oil flow upon start-up, faster oil pressure development, and quicker reach of operating temperature.

Motul 8100 X-clean 5W-40 (http://clixtrac.com/goto/?182358) is a mid SAPS, high HTHS high performance engine oil approved by multiple vehicle manufacturers. It is an ACEA C3 standard engine oil for modern vehicles compliant with the latest EURO emission regulation standards, which requires significant oil film resistance and low emission performance. Motul has developed X-clean 5W-40 with a dedicated SAPS level that generates exceptional oil film resistance, reduces friction in the engine and provides compatibility with catalytic converters as well as DPFs, whilst improving wear protection and high temperature resistance for better controlled oil consumption.
Always refer to your vehicle’s owner manual or handbook before use, and remember that with all oils, regular oil changes are essential.
