I was under the understanding that premium was required for high compression engines because of early/pre detonation. The higher octane fuels can withstand the compression without detonating prior to TDC.

If this is in fact true, and the engines are the same why would the compression on the Infinity engine be greater than the Titan 5.6L

Thanks.
