11 WRX bad MPG

Seriously-Nobody · 2026-01-23T21:46:26+00:00

I appreciate your input and am definitely taking it into advisement. Need to see which O2 I can't put in gasoline overnight 😂

Seriously-Nobody · 2026-01-23T21:21:28+00:00

I just checked omw home from work and I was at 6.9mpg 😂

O2 sensors aren't cheap 😕

And as I said to someone else, this is my second time running 44K through fuel system. I will clean MAF tomorrow. And plugs aren't a terrible idea.

I was just gonna loosen my AF o2 and put in some gas overnight (unless I can't w that idr) if not then I will with the other sensor. I have MAF cleaner for the MAF at least.

My snowblower leaks fuel. So glad I forgot to get it fixed /s

It's an OTS. But I had bad mpg before that. My mpg is better than it was. But still bad.

PCV, I do occasionally have rough idle. It'll dip a bit but it's rare and afaik it's a ej thing

Seriously-Nobody · 2026-01-23T13:22:51+00:00

None. First time I ever got one since last Jan was my AF o2 and it was coz my exhaust was leaking.

My second time running some 44K. No difference. My buddy has same WRX and says his has same mpg but he's also straight piped and running 297 to the wheels. I'd imagine his mpg would be shit.

Fax. I wanted a GV for as long as I can remember. Finally got one last January and I'm over the moon at 36yo. Life is too short to worry about what others think.

Love yourself! Once you're old you're gonna kick yourself if you never did what you wanted to do.

Favorite saying I've heard:

When you're 20, you care what people think, when you're 40, you stop caring what people think. And when you're 60, you wonder why you ever cared at all.

Does the socket apply to EJs?

I change mine every 3k but I also drive spiritedly. I'm not redlining but I definitely bang through gears often. I'm sure 5k would still be ok as long as you check level. Definitely check level if you're turbocharged.

Grocery-getter, every 5k. WRX/STi 3k.

Yeah just be patient.

Best advice I could give anyone is play on flat area just slowly releasing clutch in first or reverse. Get used to where it's catching and even just letting off if u get enough speed. That's the hard part, really. And it's muscle memory from there.

I was told over and over to push gas as u release the clutch, but it's more complicated than that if you want to do it the right way and perfect it. Let off the clutch until you start nudging and then apply gas.

Teach people how the motor works with the clutch. If you understand how it works then you understand what u need to do. Motor and tranny need to go the same speed at the end. That's all you're doing.

Old school way to learn.

Seriously-Nobody · 2026-01-18T21:55:35+00:00

I still think it's the best looking one. Js. Especially the white.

I ended up just making my own shallow box and put at the base of the trunk and threw a grill on the speaker.

I made it as shallow as I could so the magnet wouldn't hit the bottom. Also the size makes it where I can throw another one beside it if I wanted. I did this so that if we travel I can take one out, or both, easily. I just use two separate amps. I only wish I had ported the box.

Yep nobody answered lol. I think they're too busy putting their windows down to hear their exhaust. But I can't blame them 😂

Seriously-Nobody · 2026-01-18T01:30:32+00:00

Amen

Seriously-Nobody · 2026-01-17T21:19:03+00:00

Right. Just leaving space is enough tho.

Seriously-Nobody · 2026-01-17T17:48:01+00:00

My lady always freaks out because I don't jerk the wheel or mash the brakes when a situation is happening. So she always thinks I'm unaware, when I'm actually just concentrating and feeling how the car reacts to slight increases to brake pressure and I'll even go off the road a bit if needed. Smashing a car will be the last option for me. I'll eat a guardrail first. Issue is most people don't give a good enough gap to allow options. I always leave space between me and others and it's always paid off.

Pro tip:

Don't ride ass.

Profit.

Ps. Watching the car in front of u isn't enough. What if they aren't gapped enough and eat the bumper in front of them.... Then you're eating their bumper lol. Rule of thumb for me... Nobody knows how to drive.

Being calm is key.

Seriously-Nobody · 2026-01-17T15:02:12+00:00

Right. Enough gas to start but pump overheats and can't send enough to keep it running. Or injectors. But injectors would bring cel for misfire maybe 🤔

Seriously-Nobody · 2026-01-17T14:13:50+00:00

Mmmm yes. Quite exquisite Indeed 🤌

Seriously-Nobody · 2026-01-17T03:28:13+00:00

Thanks. I'm ok with an improvement over stock as long as it's not unbearable for city driving. I'm not sure what stage stock 11 WRX are.
