Is 93 Eagle Summit flex fuel?


I wouldn't think so. Flex fuel was developed after the car was built.
You could check with Chrysler or Mitsubishi to make sure.

Fuel type


Having a relatively low compression engine, you can run an 87 octane fuel in there. If ethanol is added in your area, up to 10% is fine. If you do have ethanol, don't bother adding dry gas because the ethanol is dry gas. (any alcohol is hygroscopic). Adding a higher octane fuel is a waste of $ because unless you are getting detonation, it does nothing for you.

Does the 09 es350 need 93 octane gas or will it run on 87 octane


you should have a factory affixed sticker inside gas compartment cover listing premium fuel only or also listed in your owners manual. Otherwise if you notice that you're vehicle is making a pinging sound while accelerating or climbing a hill for instance then you may want to step up to 89 or 93 octane and try to avoid purchasing fuel with ethanol added it's **** and degrades your fuel quality/octane ratio

I find that my 2006 Buick Rendezous runs better on 89 and gets better gas miles than 87. I sometimes start it and then it will have to be restarted again on 87. I even put in fuel injector cleaner and gas...


92 octane is wise to use once a month if you drive 1500 miles or more a month. Although I would use a half a tank of 92 octane when doing so. That blend has more additives which is great for larger engines such as a large V8

Why does my 87 run better on regular gas than super unleaded


the car was built to run on 87 octane, unless you have done engine work( raised compression ) or reprogrammed the pcm run regular, you will probably get better fuel economy also

What type of gas do have to use for my 2001 dodge grand caravan


87 octane or better - at high altitudes you may be using 85 octane. In spite of claims - gasoline is formulated by area - not by company. Some states require a certain formula to be sold, but it requires the same formula from all refiners. Ethanol may be allowed and I have not come across any problems using it. If you run into a driveability problem - try a different brand.

Premium 91 or 95


Hello Joshdhorz,

The best fuel you can use on your vehicle is any octane that contains at max 10% ethanol.

Ethanol is an alcohol-based fuel additive made by fermenting and distilling crops that have been broken down into simple sugars.

A 10% blend of ethanol and gasoline will not harm any engine or fuel system component. However, the ethanol has a cleaning effect that will remove rust and other junk from the fuel system. This necessitates frequent fuel filter changes until the fuel system is cleaned out.

Most gas stations in our area are set like so:

87 octane (Up to 10% ethanol)
89 octane (Up to 5% ethanol)
91 octane (No ethanol)

Now we do not have 93 or 95 octane available to us here, so I am currently unsure as to what is in 95 octane fuels. In my opinion, I would use 91 octane (No ethanol) for the majority, while adding 87 or 89 octane (5-10% ethanol) ever so often to clean the lines.

I hope this helps you out,

Shadow

Also if you would not mind taking a moment out of your day and rating my solution it would be greatly appreciated. Thanks in advance!

Gas


You can run 87 octane but here is how it works, when you run lower octane fuel the computer retards the ignition timing to keep the engine from knocking and causing damage to the pistons, this puts a big dent in fuel mileage and upper end power, the trade off is not worth the reduced cost, what if you do damage a piston, what will that cost to repair?

Right gas


Regular unleaded (87 octane) is the correct grade.
