excessive oil consumption
I have a 2007 2.5 wagon and from day one there has been about 1-2lt of missing oil at every change. Just wondering what the average was for these cars.

I have to add about a quart (a little more than a liter) per oil change. My change interval is about 5,000 miles give or take.

you should probably specify mileage instead of just oil changes. I run my oil 6k miles if its all normal driving and typically add one qt about 1/4 qt at a time. Where did you get liter anyway? do they package the oil as liters in canada or something? Also, you shouldn't find out how much oil your losing at the oil change, you should find out that its slowly consuming oil when you chk the level at gas fill-ups, like the owners manual says and a good car owner does

I check every fill-up and a liter is about a qt. but I am wondering if I just got a bad one or if 1-2 qt's was normal. I run full synthetic 10w-40. I change it every 3000 miles.

You probably shouldn't be running 10w-40...that might be the cause of the oil consumption. 5w-20 is what the factory recommends, and that's what I use. 5w-30 in July/August

and subaru's are recommended 30 from the factory, and like a thicker oil. long story short: 40 is perfect. |

I seem to be burning a quart of oil every 4,000km or so. Sometimes more, sometimes less. Sucks but it seems alot of these engines burn oil and generally make alot of noise in the winter on cold starts (piston slap?)

I;m about 1.5L between oil changes. I change it every 6000km's and I do 99% highway (150kms a day)mileage so the engine is always running. Engines will burn oil and as oil wears down it will burn off faster. Seems to be a normal thing on Subaru's I've encountered. If you were burning a liter per week I'd be concerned.

I voted twice. Once for "every tank of gas" (my stock engine) and once for "none at all" (the engine I built).
I agree that you shouldn't be running 10w40 for two reasons. First, you want the lowest possible cold viscosity you can get. No matter how warm your climate is, there's no such thing as an oil that's thin enough on startup. You always want to use a 5wXX or 0wXX when it's possible to do so without sacrificing HTHS. Second, 40 weight warm is almost certainly too thick for your engine. Subaru factory engines all seem to come off the line towards the tight end of the tolerance. I've yet to see a modern (GD chassis) NA Subaru without very high oil pressure. You need to build about 10psi per thousand RPM. Most of the ones I've investigated have been making 20-25psi per thousand RPM on 5w30 and even more on 5w40. That's just excessive and undesirably high for a number of reasons. |

My sti burns about a quart every two weeks. I was a BAD CAR MOM till around 60k. I NEVER checked the oil and was not so good about getting it changed. Shame.

as for pressure, i'm unsure as to what kind of oil pump comes on the yank engines but mine tops out @ 70psi. 120+ psi sounds ridiculous, surely you don't get that much? we have also had the wrx since the very first gen and the industry wisdom here is mildly thicker after the first 50,000k's or when you up the power at all. |

Unscrew the PCV valve from the block. Immerse it in something like liquid carb cleaner for a few minutes. Shoot some aerosolized solvent (brake cleaner) through it. Then shake it. If it clicks madly while you shake it, it's good. Screw it back into the block.

Oh, any oil with a high HTHS and a low kinematic viscosity. You can figure that out just by looking at the spec sheets for oil actually sold in your local stores. I use Redline because the HTHS is 50% higher for no increase in kinematic. There's other good ones if you dig.

'06 2.5i M5 purchased new with 0 miles
- 10k mile oil change intervals with Valvoline syn and Pure One filters. - 1liter make up oil per 3k miles since new - blackstone oil analysis at 109k miles suggested longer intervals would be acceptable. (sticking with 10k) |

lots of short trips burns more oil than fewer long trips in my experience. If I do mostly highway mileage in a change, I tend to lose less than if I run a tank strictly city driving. Anywhere from .5-1L of oil consumed between a standard interval is noted. It usually hovers around .75L
I run amsoil 5w-30 year round, just recently switched to amsoil 5w-30xlt which is slightly cheaper than the regular amsoil. |

2008 Subaru Impreza (Stock-Non WRX) excessive oil consumption
I purchased a used Impreza (19K) for my daughter last November. At the moment, it has a little over 22K and is using a quart of oil every 1500 miles.
It is not leaking and I do not see blue smoke coming from the tail pipe. Is this normal for this year? |

How do you know it's not leaking?
Measurable oil loss at 22,000 miles is not normal for any year. |

^^^ I agree!!
Even a subaru with 50-75k miles shouldn't burn more than maybe 1/2 to 1 qrt every 3k - 5k miles. But 1 qrt every 1500 miles is not right. It seems as if these engines ARE NOT being broken in right from the factory. Williaty what do you think? |
