I’m having the same issues. Thanks to living in the Midwest ? I’m running premium but thinking I need to go back to regular if it’s not helping with winter.
I didn’t know they changed fuels in the winter until a few weeks ago, during the summer I could set my Cruise control and get 41-43 on the highway, on my drive home yesterday I only got 23…
Close up… I have pulled them after a year and had them down to 0.018, I clean and re-gap to 0.030″-0.032″ and pop them back in, then replace them the next year.
Recommendations on a kind of plug. Are they a pain to get out like the dealer says. I ask them to just check them while the car was already in and it’s such and big deal to just check them, thinking maybe that could be adding to my mpg and performance issues but nope they can’t do it without a charge.
@Corey I almost thought this was a Subaru group. The only hassle is the boots possibly tearing. Silicone spray them and you should be fine. A hassle is taking half the car apart to do turbo Subaru plugs.
Have you guys changed to winter fuel? that drops MPG I am told.
I believe so, just think that’s kinda drastic. Not only that I see people saying they getting 40 mpg and I’m bone stock as far as performance
From bnr?
Has to be winter fuel.
My Cruze went from 31 mpg to 26.
Time to trade it in if only I wouldn’t be taking such a hit on it.
I should’ve returned mine to CarMax within that 5 day return period they offer. ?
Just glad I live in a warmer climate, I really don’t notice much difference no matter what season.
I live in California. It might just be an American thing.
Maybe the oil company just makes one mix of fuel and everybody gets it?
@Umar How cold can it get there in California?
It snows in Northern California
45 degrees right now in ny where I am.
In CA, worse I’ve seen recently was around 53°F, @Rini. We’ll see if global warming takes affect.
Is that day or night temperature?

Regular may also take the same hit in MPG. Just remember if it warms up, the MPG loss will happen from 87 fuel map.
Nooo…. You don’t want to switch back to regular
It costs more but non ethanol fuel doesn’t take such a hit.
Can’t find it here and it’s 87 when you do.
There are apps or in google maps you can look them up. Also most truck stops have them.
@Jason I tried that too and didn’t help.
Your engine will also take longer to warm up and thus it runs a richer mixture for longer.

It’s definitely the winter blend. My mpg went to hell when it switched
I’m down to 27 average from 32-34 also.
Mine went from full tank at 500 miles to 380 at full
I haven’t looked at my MPG yet, tire PSI is screaming super cold is upon us.
How many miles? more than 25k replace spark plugs or at least gap and clean… mine seem to close up quite a bit about every year or so.
Close or open? Mine usually open.

My car is at 27500 and I checked gap a couple weeks ago and they were at 0.024, set em at 0.027 and put em back in but may change em to a colder plug

They were saying gotta take off a fuel rail and coil packs
We talking diesel? If so then yeah not as simple as gas. I literally just did this to find out I need more “spark” plugs about an hour ago.
Haha I would think so as there’s no spark plugs but no typical 1.4t
Yeah makes sense. The fuel rail for us stays on in 97% of the times we work on the gassers.
So is it typical pull boot, pull plug or is it complicated like they say?
What kind of plug should I put in?
I leave it plugged in, the plug gets brittle and the orange(11-12) or purple (13+) tab sometimes like to break.
The thread you want is “hesitation gone” on the forums as the ideal plug changes due to driving habits.
My diesel has gone from 48 to 42 but I also idle it 15-20 mins a day now where I would start and go before.
It’s because gas stations switched to winter fuel now
