Hope you're not "jamming" too much fuel in after the pump stops. A little seems to be ok but (in case you're unaware) that habit has resulted in an expensive evap system repair for plenty of members.

  • Switching from 100% gasoline to E15 (15% ethanol) will lower the MPG by 4.5% and therefore reduce the vehicle range per tank-full by 4.5%. This is because ethanol has 30%+ less energy by volume compared to gasoline.
  • Ethanol will corrode some metal and alloys. Ethanol will also degrade some polymers, fuel hoses for example, and cause them to swell and/or fail. So, if your vehicle is not certified, ie 2.5L engine, to run E15 then one should expect related issues and a shorter life span of important fuel related parts. Trade your gasoline powered vehicle for an electric vehicle and the problem goes away.

^ Pretty sure you've already posted most of that in this very thread (e.g., page 5), or it's at least been covered by other members. Anyway, none of that appears lost on anyone participating in this discussion.

Even though my vehicle is certified (according to the car's manual), I will keep away from using E 15 if possible.
Thank you,

Just because one's vehicle can use E15 doesn't mean it's ideal or you should.

The purpose of the E15 allowance by the Administration isn't for cleaner air but rather to put more fuel into the supply chain leading to lower prices.

Guacamole with some fresh squeezed lime and sea salt is something you can eat with your eyeballs but when you water it down with other ingredients it's still called guacamole but I'm not that interested.

You don't have to put doctored up guacamole in your car.

  • More ethanol in gas the lower the MPG = more fuel used = more taxes collected. So, require more ethanol in gasoline to collect more tax money.
  • The more ethanol added to gas the shorter the predictable life span of gasoline powered vehicles.
  • Originally seasonal additions of ethanol to gasoline was blamed for rise in gasoline prices and now some are suggesting the addition of ethanol will lower gas prices. Go figure

E15 may increase the available volume by 5% over E10 but reduce the total gain by 4.5% due to the reduced MPG. The damage to most cars will reduce their useful life and add to maintenance costs. However, this is not a problem for those with Big Black E85 Suburban SUVs.

such as the "BEAST".

In conclusion, if your XT vehicle's manual says you can use E15 or lower then it should be OK. You just have to know that the 2.5 manual has a limit of E10 for the same year G6.

From my Outback manual..........
Use only unleaded gasoline with an octane rating of 87 AKI (90 RON) or higher.
Limit of ethanol content
2.5 L models: no more than 10%
2.4 L models: no more than 15%

Some recent political commentary has been removed from this thread. Please, folks - we previously laid out the rules here; a thread such as this needs to keep to some established boundaries because of the nature of the subject at hand.
