I hate to start a whole new topic for this, but i had to.

Ive always wondered why the 4 cyl. take more oil than our 3.4's?????

And another question. I just bought a drop in K&N Air Filter, does anyone else have this????? if you do, have u noticed a difference in performance?

Thank you to anyone who takes the time out to respond to this.

i had a drop in k&n back in the day. back then i would swear and declare it added performance and what not but hind sight tells me it was a seat of the pants kind of thing. all it really does is improve gas mileage a wee bit.

True that, most mods will but up MPG.

I would think the 4 banger takes more oil since it will rev a bit more and heat up quicker. PLus it most likely have a bigger oil pan

what do the 3400 rev to??? my ecotec revs to 6400 and keeps making power right up to rev line

As far as i know, the fuel cut-off on the 3400 is 6200 RPM. Fuel cut-off is at 6500 on the Ecotec. I know the V6 is mechanically limited to about 7000 rpm before the rods need to be upgraded.

5800 rpm for the 3400

Wow, that sucks... it definitely has much more potential. Mine is limited at 6200.

how much oil does the 3.4 take.? I know the ecotec uses 5 qts.

The 3400 in the Alero is red lines at 6250, but is can rev to around 6300 to 6400.

My mech, and s/c alero (a GM tech in Denver) both said that

The 3400 takes 4.5 quarts.

I was surprised when I first got the Alero. I have never seen a 4cyl take 5 quarts of oil. I have had 3 other 4 cyl cars, and most took 4 qts for the exception of my Mazda Protge, and it only took 3 qts.
