Default 06 2.5i oil consumption

just wondering if anyone else is having this problem or do i need to go to the dealer, even though i think they voided my warranty for aftermarket parts


i use mobile 1 5-30 and use about 1.0-1.5 quarts every 3500 miles or so.

i change my oil every 3000, was told i was wasting oil and to wait till 5000 or longer,, just hit 5500 miles on mobile 1 5-30 and wasnt even on the stick about 2.5 quarts low. any help would be great.

Jesus, just search. You'll find eleventy billion people bitching about oil consumption. You'll also find that a lot of them are bitching specifically about Mobil1.

Maybe you should top it off when it gets low?

Lol, you know, about a month ago, there was a thread by a guy who was checking it regularly and noticed it consuming a lot of oil. Tried to figure out why. Never topped off the engine, blew it up.

my EJ253 used a lot of Mobil1 5w-30. About 1.5qt per 3000-4000 miles. i have since changed to AMSOil and the consumption is significantly less. im maybe .5qt low @ 4000miles. And it's better oil, to boot.

Got you all beat. I'm eating a quart of Redline 5w30 every 1200mi.


Race, which Amsoil are you using?

im using their 5w-30 full syn. Here it is im also using their Ea filter, which is supposed to stop 97% of particles down to 13 micron i think. I'm @ just over 4000 miles on my first amsoil change and the oil looks remarkably clean. ill be sending out a sample to blackstone after the holiday vacation to see how the oil is holding up. the AMSOil dist. said i could run it 25,000 miles/1yr between changes with that filter... which i would never do but i thought that was quite the statement when backed by their warranty.

God, that's even more expensive than the Redline I'm using.

yeah, its not cheap at all, but its still only $50 or so per oil change. and if it goes 8000+ miles per change, ill be very happy. I look forward to the oil analysis results.

Yeah, but it has to actually stay in the engine that long to make it worth it

touche. But it is seeming to hold onto the oil better. 1 qt/8000 miles is my guess. thats about the avg for any car, not bad for how I drive her, either.

Just so you know, your warranty isn't voided, but you may have trouble if the affected component is the result of the aft. part. What mods do you have?

And as was said earlier, check your oil level (frequently) for God's sake. I'm pretty sure you drove more than a tankful of gas to be down 2.5 qts.

No noticeable issues with mine, but I just have the dealership do it every 3-3500 miles. Apt living FTL

I'm just using Castrol Syntec 5w-30 and a purolator filter. That one filter you posted, RaceFace, sounds amazing, wow!

It was time for one of these again... I too drank M1, as well as royal purple. GC (0-30W) cured most of my consumption issues and isn't too thick for those cold -20F MN mornings.

Here's a question for group: What else factors into or contributes to oil consumption aside from poor/failing rings and oil viscosity? Have heard alot of high RPM driving, PCV, tuning/modifying can all drastically alter the rate at which an engine consumes oil...

Lateral G's and manifold vacuum are two BIG contributors. Lateral G's sling oil into the valvecovers, which then gets sucked up the breather lines. High vacuum (high revs esp. with the throttle closed) cause both the PCV and valvecover breathers to flow more.
