Frequently asked questions
What should I do if I put the wrong fuel in my Porsche Porsche?
Do not start the engine or cycle the ignition to RUN if the fuel pump may prime. Have the vehicle recovered to a USIFDA Certified Repair Facility and follow Porsche service information for tank draining and fuel system inspection.
Does Porsche warranty cover misfuel damage on a Porsche?
No. Porsche warranties exclude damage from improper or contaminated fuel. Repairs are typically customer-pay; document the OEM-prescribed remediation procedure.
Can fuel be removed from a Porsche through the filler neck?
Porsche documents fuel recovery via the fuel pump module access and/or tank removal using approved equipment—not filler-neck siphoning. Follow ISTA/TIS or erWin procedures for your model year.
