Fuel type ///mpg

Recommended Posts

Hi everyone!

 

Since i first bought my Journey RT few months ago, i always used 87 Ethanol. The MPG was really bad, i read a lot online and found out that 89 and 91 will have a better MPG. Not a performance, since the pentastar is tuned to run 87. So staring today I started to put 89.

 

What are your thoughts? What do you advice? 

 

Thank you in advance for your help.

Personally a waste of money on an engine designed to run on 87. What mileage do you consider "bad"? We average maybe 19-20 around town, up to 26-28 on trips. That is very acceptable to me.

Yes 20L/100km is rotten mileage.

It depends on several factors such as geography,temperature,vehicle weight and

least but not last your driving style in any given traffic situation.

AWD does worse than FWD as a rule.

I don't know. I only know MPG's.

Sorry, in MPG it is  : 14-15.

 

After a full day driving, i noticed a better performance... how is that possible? 

 

Thanks.

Its a brand new vehicle that needs to be broken in. Give it some time and dont waste your money on a higher octane

AWD makes a difference also

Hi mfeel

 

We have two 12 R/T AWD Jouneys with the 3.6L pentastar .  We average about 12.5L/100KM city and about 9.8L/100KM on highway - over the last 5,000kms.

One has 78,000 kms and the other has 36,000 kms on the clock - both are about the same.

 

bigtsr and larryl are both correct.  New vehicles take time to break in and the mileage should improve - but it really depends on your particular driving style and how much time is spent sitting in traffic - stop and go driving, hilly terrain, etc...

 

I would reset my mileage clock at every fill up - but then if I spent the first half a tank of gas in city mode only with little or no highway trips my gauge would tell me I was at 18.5L/100kms - Yikes.... all city - stop and go , etc... but over 10-tanks of gas you should get a pretty good feel for the mileage that you are going to get.  On the highway - you can expect to get down to 9.5L - 10L / 100 kms - so longer trips it will do pretty well for its size and power (283HP after all).... speed plus the AWD will be negative factors.

 

My two - cents - for what it is worth.....

I'm averaging circa 10.5L/100k.

 

on the highway it's usually around 8L/100k though. Using 91RON unleaded which is standard fuel here.

Ahh yes! On the highway it is amazing. I went to new york in the summer, it was down to 6.5l/100km! Anyways, thanks everyone. I really appreciate

is it bad to run 85 octaine in these engines?  im on my 2nd tank of gas.  the day i bought the car the sales guy put in 85.  i put 85 in the second tank as well. 

 

 

i ask because is it REALLY a bad thing to run 85?  i mean is running 87 a scare tactic?

I would put what the manufacture recommends, they built the engine and know what it needs to be healthy. Octane is resistance to detonation. Higher compression needs higher octane because when you slam all the air and fuel into a smaller space (higher compression) it results in hotter temperatures. Gasoline will self detonate when it reaches a certain temperature based on the octane rating. If octane is too low you risk detonating and causing engine damage. So i would put 87 or 88 depenging on what you get where you live.

 

Where i live the pumps have 86, 88, and 90 or 91. so since 86 is lower than required i use the 88, no reason to go any higher as it will have zero effects on mpg or performance unless tuned for it. But definitely dont want to go lower than 87.

do it yourself for $20.

 

the journey is the easiest vehicle Ive ever owned when it comes to oil change. dont even need a jack. takes 10 minutes. and all you need is a single wrench..... if oil filter was put on properly it will come off by hand.

lol that was supposed to be on another thread, i had two tabs open and thought i was on the other one.

 

and also i meant around $30. 25 for oil and a few bucks for filter.

 

this was supposed to be a response to someone that had paid a dealer $140 for an oil change

no regular 85 octane.  here in Colorado we have 85,87,91 octanes.  in some rural areas we have 89 octane

 

ive never used E85.  our grand caravan allows it too but ive heard good and bad about it so ive never tried it LOL.  and ive always used regular 85 in it too.  i guess since its the same engine i should use 87.

 

as for the journey, i guess ill be using 87 then.  ill be filling it up with its 3rd tank fill tomorrow too!

I agree with jkeaton 19-20 is my average 3.6l v6. (Heavy on the foot too traffic isn’t heavy though). And I get the full 500mile claim going to Vegas. (Reg 87 fuel ⛽️)

It's the same in Utah and Idaho, 85 is the lowest, then 15-20 cents more for 87.  I have 130k miles on my DJ, always running 85 octane for 5 years.  Never had an issue so far!  I figure over the years I've saved probably over $1k in the difference of fuel costs...
