Is it worth putting 91 instead of 87?
The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. Premium gas is not “stronger” gas.
What burns faster 87 or 91 octane?
Fuel with an 87 octane rating burns more quickly while higher-octane fuels burn more slowly. By contrast, a higher-performing engine, which includes engines with higher compression ratios and/or forced induction, requires the slower burn rate of higher-octane fuels to defend against engine knock.
