ehsnils Posted January 7, 2011 Share Posted January 7, 2011 And maybe you should try to look at the instant consumption indication while driving uphill the same hill on different gears at the same speed and see what the best alternative is.

blongo804 Posted January 7, 2011 Author Share Posted January 7, 2011 My daily drive is about 3 miles to school, then it sits about 8, then another 3 home all uphill. That's actually a good idea to do the instant mph while going uphill and reading off that. The current oil I'm running is just regular oil (not sure if that has weight numbers?). We just put a new shortblock in about 2000 miles ago and now just breaking it in. My next oil change maybe we should use synthetic? Link to comment Share on other sites More sharing options...
Instanced Posted January 7, 2011 Share Posted January 7, 2011 13mpg is definitely still horrible even if that is the true mileage.. From what my father is saying, the injector numbers read correctly. I *think* he said the O2 sensors would be reading off or a CEL would come on if that was the problem. Maybe I have a leak but wouldn't I smell something or no? Thank you to you guys trying to help. I appreciate it highly and we will figure this out! a leak wouldn't necessarly produce a smell... just spend a couple hours looking at all your hoses and tracing them to the motor and to their external connections... I think it's something to do with your injectors. If I were you, I'd probably unplug my battery for a night... let the car relearn how to drive so to speak... maybe it learned how to be an arsehole driver and suck gas down quickly heh first things first... Calculate your MPG and let us know. EDIT: I would use another round of regular oil... then switch to synthetic... personal opinion. Link to comment Share on other sites More sharing options...
blongo804 Posted January 7, 2011 Author Share Posted January 7, 2011 Thanks for the advice there, Instanced! Maybe I can convince my dad on Saturday to examine hoses that could be leaking. (he's the brains here of course haha) Honestly with the life my car seems to have gone through, I wouldn't be suprised if an arsehole owned it before me. I'll stick with regular then for one more change. Not sure what my father even planned. We're definitely going synthetic but I forget when he said. Probably going with Rotella T 5w-40 as it seems everyone on this site loves it! Link to comment Share on other sites More sharing options...
Luchin Posted January 8, 2011 Share Posted January 8, 2011 I also find that if I keep my car in it's powerband I get slightly better gas mileage then if I drive like a granny and let it drop under. Where is the power band on these cars. Link to comment Share on other sites More sharing options...
Guest PeteAWD Posted January 8, 2011 Share Posted January 8, 2011 If you do not run 91 or 93 octane in a 05 LGT, the mileage will get worse. This care craves premium high quality fuel only. Why I don't know. I drove it off the lot with 12 miles and it now has 135k. Also verify your alignment, tire pressure 35F/33R and tire type. BF Goodrich G-forces were horrible. Michelin generously replaced them for me with Pilot Sports. I'm getting 21 highway and I drive it aggressively. Link to comment Share on other sites More sharing options...

I guess cause I went hipermilling like a prius owner til I was able to get to Ft Dix and pump my own damn gas! These cars want a minimum of 91 for safety reasons. Even the n/a cars that don't have turbos that run 91 need special care when 87 is used in emergency situations. The used car dealers were notorious for blowing up cars like the marauder cause they would put 87 in and try to redline it back to the lot. I don't lend my car cause most people needing to borrow it will run 87 and drive it like they seen me drive it. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...

We just put a new shortblock in about 2000 miles ago and now just breaking it in. My next oil change maybe we should use synthetic? In your case I would definitely say that it's the short drive combined with an oil that's thick when it's cold. An oil change to 0W30 or 0W40 would really be an alternative - not 5W30... And then check the consumption again. 3 miles is a very short distance and the car won't really even get warm, which explains the bad figures. I did change from a 10W to a 5W a long time ago on a car I had and at that time my driving distance was about the same. I did experience a noticeable change in consumption.

blongo804 Posted January 8, 2011 Author Share Posted January 8, 2011 Thanks for the advice. I'll probably be changing to synthetic in two more oil changes..unless i'm broke by then with buying gas for this thing. I do also use an auto-start each morning. I let it run before school for no more than 5 minutes (believe me, I pay attention..don't want to waste too much gas). Even before the auto-start though, I was never averaging more than 14mpg, so I can't blame it. Link to comment Share on other sites More sharing options...
ehsnils Posted January 8, 2011 Share Posted January 8, 2011 If you switch to the synthetic 0W30 right away and skip the 5 minute warmup (aside for the time it takes to remove any ice from the windows) you will certainly save a lot. As long as you drive it soft and nice while it's cold there is no need for it to stand idling for five minutes. Many places around here has a law that says it's illegal to idle a car for more than a minute too. If you really want to improve and if you have the possibility (electrical outlet at least at home) - install a block heater. Link to comment Share on other sites More sharing options...

You can always do the same by getting a AVO AWGA and extend the arm too far. Might have a slight pulsating metallic rattle and carbon deposits falling out of your exhaust if you have a high flow cat. Most scariest sound ever. The blown turbo popcorn sound didn't even sound as scary as the WG rattle. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...
notthesnail Posted January 11, 2011 Share Posted January 11, 2011 Seriously, change to 0w30. You're not getting the car hot enough to run 5w40, especially in the winter. If you're not going to be taking it to the track or autocrossing it, you can safely run 0w30 synthetic all year round, and you'll get better milage than 5w30 or 5w40. At 2000 miles your engine is broken in enough to switch to synthetic at any time. Extended break-ins are a thing of the past. When it's cold, the trans fluid can benefit from a short warm up, maybe a minute or so while you clear the windows, but more than that is a waste. My trans won't shift into 5th for at least a mile, depending on how cold it is, but a short warm up shortens that. If you have a laptop, get a VAG-COM or used Tactrix cable and find a stage 1 tune for your car. You'll get a little more pep and slightly better milage, maybe up to 10%, since they usually don't run as rich as stock. You can log to verify, but the ones I've seen are pretty well tested and logged, and pretty conservative. Actually, when you do this and log, you can post the logs in the tuning forum, here and on other sites, and get some experienced opinions about your state of tune. If there's a problem, this might help pinpoint it. Link to comment Share on other sites More sharing options...

In all seriousness if you barely ever boost or drive fast a 2.5i with leather and sunroof is not a bad choice. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...

All depends on the circumstance. For example the 2.3 mazda 6 manual was almost as fast as the 3.0 automatic and due to the 3.0 weight on the nose of the car the 2.5 was more nimble in AutoX. the V6 had to have straights to balance it out or they always had lower times. I test drove both cars and a WRX. None were exactly the same to me. Had the 2.5gt on a cobb eco tune was slow but it didn't feel like it lacked response or oomph. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...
fishbone Posted January 14, 2011 Share Posted January 14, 2011 When my t-line blew a vacuum hose I was still boosting at around 11 PSI which I think is quite enough to pull away from a 2.5i At Stage 2, the car is peppy even when not in boost.

Merc6 Posted January 14, 2011 Share Posted January 14, 2011 I wish. once the needle 0 on the boost gauge when it was just a small leak and didn't separate, the GFB GT 50/50 opened and stayed open. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...
Luchin Posted January 15, 2011 Share Posted January 15, 2011 Well I'm getting crap mileage as well. I just filled up today after having only driven 203 miles. My car took 13.9 gal of fuel. If you do the math I'm getting 14mpg. I drive in sport mode most of the time and I don't drive hard at all. If I kick the shit out of my 09 TSX in city driving the worst mileage I ever see is 21 mpg and that's accelerating hard and shifting at ~4500, If I drive it like I've been driving my OB I get 26 mpg in the city. I put some injector cleaner in this tank so we'll see what happens. I will use some break cleaner on the MAF sensor tomorrow. Link to comment Share on other sites More sharing options...
