Oil Question- .3qt Too Much!

Sinister Subaru · 09-04-2005, 01:50 PM

I got my oil changed yesterday (didn't have time to do it myself and dispose of materials) so I decided to hit "The Lube Shop" here in Frederick, MD where Matt, (another member) works, and I had spoken to him in this forum, so stopped up to meet in person.

Someone else changed the oil, not Matt. On my invoice, it has listed that they filled up 4.5qts, and when I woke up this morning, I checked my owner manual and it said that the motor takes around 4.2qts, I believe. Am I going to damage anything with the extra .3qt of oil? It's not enough to cause valve float or anything, is it?

I know this is probably a stupid question, but I figured I'd ask, just because I'm paranoid.

Can anyone help me out?

Thanks!

It's fine. An extra quart too much might be cause for concern, but you don't need to worry about that little bit. Drive on.

lol i usually fill up with like 4.7quarts of oil, which reaches the max fill line on my dipstick.

Cool! Thanks, guys!

i think it should be 4.7qrts, there is a post around somewhere from a email from subaru that said the 04 manual is a misprint it should be 4.7 not 4.2

You're right-the correct oil capacity for the 05 is 5.1 qts for oil and filter change as per Subaru. The owners manual wasn't updated for 05-don't know about 06.

boostin04 · 09-06-2005, 01:12 PM

What about for the 05s ? The manual still says 4.2 qts. Is that a misprint as well ?

Did you check your dipstick to see what the level was?

The shop that changed my oil stated on the invoice they filled with 4.5 qt. It looked a little bit high. Maybe the 4.2 qt recommendation is correct? I think you're best going with the Subaru recommendation in the owner manual. That way, if anything were to happen, they can't say that you didn't follow the recommended oil levels.....

I have taken it upon myself to contact Subaru and find out for sure what the correct recommended oil capacity is for the 2005 STi.

i change my own oil and have gone through 3 of them so far.

at about 4.5 quarts with out starting the engine to fill the turbo lines & oil filter, it "appears" full.

once you crank the engine a few times and let the oil flow through the engine and re-check I always have to add the last of the 5th quart. at 5.0 quarts im right at the full marker.

I let my oil drain from the pan and the filter until it starts to form droplets.

If I'm not mistaken that's 4.2 quarts not including the capacity of the oil filter....every oil change I've done on my 05 has taken right at the 5 quart level including filter

I have 4.5 qts in right now with a filter and it too reads just a tad high. not bad though and nothing to be worried about.

I do wonder though how Subaru could make a 300 hp 4 cyl, with variable tq setting differentinal, a trans that handles twice the out put of stock BUT can't seem to make a dipstick that reads correct half the time. Go figure...

lol....I had to ask my tuner on how to correctly read the dipstick...the oil level seems to be lower on one side of the dipstick plus you have a notch in it as well...and the owners manual tells you how to "read" the dipstick correctly...
