chevron group II base oils Simplifying a complicated world of tightening specifications starts with Chevron With an extensive portfolio of qualifications in place, we can help you optimize formulations across your entire product line. Our Group II base oils have purity comparable to Group III, and they are available in a much broader viscosity range. So you can optimise formulations for 5W, 1W, 15W and 2W engine oils, as well as the majority of your industrial oil formulating needs. High purity enables economic formulations for demanding AEO specs Low sulphur for low SAPS formulations Low volatility for reduced oil consumption Excellent oxidation and thermal stability for extended drain intervals Excellent soot handling (dispersancy) for HDMO

modern heavy duty engines need chevron group II base oils Large diesel engines are subject to grueling workloads. They need lubricants with sufficient high temperature/ high shear (HTHS) viscosity to 7 6 5 Large truck power Large truck torque 25 2 ensure adequate wear protection for the long haul. They also need lubricants with minimal amounts of sulphated ash, phosphorous and sulphur (SAPS) in order to meet tightening emissions specifications in many locations around the world. Power, kw 4 3 2 1 Passenger car power Passenger car torque 15 1 5 Torque, Nm 1 2 3 4 5 6 7 Engine speed, rpm Protecting heavy duty engines High torque + low speed = lubrication film breakdown Engines depend on the continuous presence of a very thin millionths of an inch film of lubricant between moving parts. If there is insufficient lubrication, or if the lubricant has lost its lubricating properties, the result is metal-to-metal contact, increasing wear and ultimately engine failure.

heavy duty motor oils heavier base oil viscosity improves performance In HDMO, wear decreases as viscosity increases Commercial proof Wear scars from three sooted HDMOs MTM test at 1 C 8 Better Wear scar diameter, um 7 6 5 4 3 2 1 5W-3 1W-3 15W-3 Better Wear scar diameter, um 8 7 6 5 4 3 2 Fresh 5W-4 15W-4 synthetic group II Same viscosity at 1 C 3% soot 5W-4 15W-4 synthetic group II The improved fuel economy in long-haul trucking is minimal when going from a 15W-3 to a 5W-3, while the wear risk goes up substantially. The only way to mitigate this is by using more expensive and complex additive technology. The commercially available lubricants tested had E9, CJ-4 and multiple OEM approvals. The lubricants in this test formulated with Chevron group II base oils provided better wear protection than the full synthetics formulated with group III base oils. Proof that a heavier base oil viscosity is critical to wear control.

heavy duty motor oils formulating for performance and economy Chevron group II base oils are the optimal alternative for meeting tightening HDMO specifications. They have the higher viscosity needed for extended wear protection as well as the purity necessary for tough low sulphur specifications. Chevron group II/II+ base stocks are essentially sulphur-free.

heavy duty motor oils reduce complexity and costs with global formulations Pressure differential scanning calorimeter (PDSC) by CEC-85-T-99 Engine manufacturer consolidation is leading to global OEM specifications. Formulating with Chevron Group II/II+ is an efficient global solution. Qualify in one market and you can formulate anywhere in the world without additional testing and costs. Plus, with a large portfolio of qualifications in place for a broad range of ACEA, API, JASO and OEM specifications, your initial approval process may be more efficient than ever.

In the commercial oils we tested, the 15W-4, blended with all Chevron group II, performs statistically better than the HDMOs blended with group III and comparable to the one blended with PAO.

passenger car motor oils pcmo - optimise formulating costs for premium lubricants with group II/II+/III blends Lower cost for your largest volume lubricants While W lubricants get a lot of attention they are a tiny fraction of the market. 5W and 1W lubricants represent the largest market share of automotive lubricants in many parts of the world. Formulating work with major additive companies shows that both of these products can be blended with 1% group II/II+ base oils with no loss in performance. In fact, more than 9% of the world s automotive engine oil volume, both for heavy duty and passenger car motor oils, can be blended with the majority component being group II. Lower total formulating costs for your blend plant With Chevron s group II base oils as the cornerstone of your blending strategy, lubricants ranging from heavy monograde to high performance multigrade motor oils can be produced while minimising formulating costs. In many applications, optimised group II/II+ formulations can reduce costs while delivering comparable, or even better performance than Group III based formulations. This gives you the greatest flexibility in responding to market place needs.

chevron s diagnostic tool shows how to optimise formulations Graphic diagnostic tool identifies optimal blending ratios By graphically displaying the performance range of base oil blends, one is able to identify the most efficient blend for meeting a desired performance objective. How it is done: Curves are created by blending two base stocks in varying ratios Target base oil blend viscosity and volatility is established by backing out contributions from the additive and viscosity modifier (VM) packages If the curve lies below the target, the blend of the two base stocks is capable of meeting or exceeding the volatility and viscosity requirements In some cases, a third base oil, (correction fluid) is required to meet specifications.
