BMW uses low tension piston ring sets on purpose. They provide less parasitic drag on the cylinder walls and superior cylinder lubrication at high RPM high load. Small and large high specific output engines from many brands use this strategy. Not a problem. They are designed this way for A reason. Its not the oils fault they chose this engineering compromise. ********



I already explained the ring pressure issue. Here it is again.


This low ring pressure is not an engineering compromise.......it's an engineering achievement!

All engineering is a combination of compromises. It is possible to go to far with any of them. The best choices are a matter of constant debate and tend to become self evident over time through successes ,failures or plain mediocrity. Some companies are better at making these decisions than others. The same goes for oil companies and car companies.
