What is causing the 90% isooctane level to be between 160 and 170? It used to be between 145 and 154; it has risen recently

Generally, impurities in the raw materials such as butadiene and propylene. Acid concentration, space velocity, and an excess of light components in isooctane also affect the 90% boiling point.
