Greetings,
I don't have much time to get the Boxster out, and she can sit for weeks on end under cover in the garage. I worry about the gas getting stale, particularly E10.
Are you guys treating your E10 with anything other than Stabil? There's a product called Stabil 360 (evidently for marine use) that claims to correct the ill effects of E10. I don't even remember if E10 was around when my car was built in '98.
The Boxster is not on the list of Porsche's that they recommend not using E10. Wawa's in my area have ethanol-free "marine fuel," so should I be using that instead? I just don't remember what octane it is. Likely 89.
Any input would be most appreciated.
