Strongly considering the Dodge Dart turbo with the rallye package. Is it true that regular gas can be used or is premium mandatory. We have gotten 2 different stories. We thought someone here could enlighten us better than the dealer.

You can download an owners manual here.

87 can be run but they recommend 91 for the turbo.

 

[beepahh]

owners manual states 91 recomended.........i use it and achieve 40 mpg

My gf had put regular in and I told her to put premium in cause of all the turbo cars I have owned thats what I used. So then she put in 93 and mixed the 2 and I noticed the car acting a lil funny till it ran out. My question is what about e85? I know on my dsm's u had to change ur tune and injectors but cars now days come from the factory with them ready to run e85.

 

[jkelly16]

All cars are not designed to run E85 and I don't see where that's a recommended fuel in the owners manual. This warning is in there on page 464 along with more info on it.

E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline containing
10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.

From the Manual if one has the 2.0 or 2.4 L engines:

" This engine is designed to meet all emissions regulations and provide excellent fuel economy and performance when using high-quality unleaded “regular” gasoline having an octane rating of 87. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines."

For the 1.4 L engine:

" This engine is designed to meet all emission regulations and provide satisfactory fuel economy and performance when using high quality unleaded regulargasoline having an octane rating of 87. For optimum performance and fuel economy the use of 91 octane or higher is recommended."

You can see if your engine is 1.4 L, 2.0 L or 2.4 L by opening the hood. It is stamped in large print on top of the engine.

To view that, use the hood release which is a flap on the underside of the dashboard beneath the external light controls. A second hood release is under the hood facing the front to the right of center from the user's view.

I'm on my second tank of 87 octane without any issues at all. I will be trying 93 on my next fill up to see if I notice any differance. I'm getting 35.7 MPG right now with a mix of city and highway driving.

you can use regular gas but you will get better gas mileage with premium. I used regular gas for a about a month when i got mine to see how the mileage was, but according to the manual - 87 octane (acceptable) 91 octane (recommended).

You get a little better gas mileage with premium in the turbo. Performance difference is negligible.

 

[dleininger]

In my area there isn't a 91 grade octane, only 87/89/93. I run 89 midgrade now after using 93 premium for the first couple of months and I can't really tell any difference in performance or MPG.

I've had my Dart 1.4 turbo, DDCT for 4 months, have used all three grades, 87, 89, 93, No noticeable difference in performance. On one tank full of 93 I actually dropped 1 mpg from the tank of 87 that I had filled up with prior. 30 mpg to 29 mpg around town.
The most noticeable was when I started using the A/C, I dropped about 2 mpg.

 

[mydart13]

i may be asking a q that may have been answered, but can u run e10 in the dart on 87 octane?

Calculating mpg

I've had my Dart 1.4 turbo, DDCT for 4 months, have used all three grades, 87, 89, 93, No noticeable difference in performance. On one tank full of 93 I actually dropped 1 mpg from the tank of 87 that I had filled up with prior. 30 mpg to 29 mpg around town.
The most noticeable was when I started using the A/C, I dropped about 2 mpg.

The only accurate way to calculate mpg is to use one of the Trip history calculators in the EIC to measure miles between fills to full tank. Then divide those miles by the actual number of gallons used to fill the tank.

That calculated mpg will be far less than the EIC display of mpg since the latter only measures moving mpg. Stationery mpg is always ZERO and is only reflected in the calculated mpg - NOT the EIC mpg.

I'm curious to know how your EIC mpg for a full fuel cycle compares to your calculated mpg for that same cycle.

I use 87 most of the time. seems to not be an issue. I ran 91 for my long drive though just to help out with mileage.

 

[chizzle1]

the only time the octane rating will come into play is under acceleration (boost). The higher the octane rating the compression the fuel with withstand before detonating without spark (aka spark knock).
Modern engines have knock sensors, which will retard timing to eliminate said knock, preventing engine damage.

hi guys im a recent dart buyer (awesome car) i try to find excuses just to drive it. kinda like the commercials "need milk, ill go get it"! im trying to find out what gas i need though, before the gas is needed lol. i have a 2013 dodge dart limited multiair turbo. from what i see that model has many models. is there a way to determine which one i have? the manual is a generic one, it mentions multiple models.

For the 1.4 L engine:

" This engine is designed to meet all emission regulations and provide satisfactory fuel economy and performance when using high quality unleaded regular gasoline having an octane rating of 87. For optimum performance and fuel economy the use of 91 octane or higher is recommended."
