since theengine's "Electronic Oktane™knockcontrol" willadapt theignition timing,ifnecessary.

Fuels containing alcoholandether

Some areasofthe U.S. require oxygenated fuelsduring certain portions ofthe year.
Oxygenated fuelsarefuels which contain alcohols (suchasmethanol orethanol) orether (such asMTBE).
Under normal conditions, theamount ofthese compounds inthe fuel willnot affect driveability.
You may useoxygenated fuelsinyour Porsche, providedtheoctane requirements foryour vehicle aremet.
We recommend, however,tochange toadifferent fuelorstation ifany ofthe following problems occurwithyour vehicle:
- Deterioration ofdriveability andperformance.
- Substantially reducedfueleconomy.
- Vapor lockandnon-start problems, especiallyathigh altitude orathigh temperature.
- Engine malfunction orstalling.

Fuels containing MMT

Some NorthAmerican fuelscontain anoctane enhancing additivecalledmethylcyclopentadienyl manganesetricarbonyl(MMT).
If such fuels areused, youremission controlsystem performance maybenegatively affected.
The check engine warning lightsonyour instrument panelmayturnon.
If this occurs, Porsche recommends youstop using fuelscontaining MMT.
