How MUCH oil?


Recommended Posts

Posted

My mechanic has always put in 5 Litres of Mobil 1 Synthetic every time I've had an oil change done.

 

I recently found that my Owners Manual states:

 

4 qt (US)

Note: Additional oil may be required to bring oil level to full mark when changing oil filter.

 

If 5 Litres = 5.2835 US qt's, does this mean my mechanic has been putting TOO much oil in my 2.8L engine? Or is it really no big deal, and nothing to worry about? I assume it's impossible to predict just what exactly is meant when GM says "Additional oil...", I mean how much is considered too much? Is 1.3 quarts too much?

 

How much do you 2.8-3.1 guys put in when you change your oil?

 

THANKS!:)

If using the shorty filter @ 4.25 quarts - right on with the dipstick

If using the bigger compadable filter @ 4.75 quarts - right on with the dipstick.

Who told you to put 5 quarts in? Surprized it hasn't blow-backed or foamed on you! :shock:

wtf. i have to put in 6 qts. sometimes 6.5 qts.. its freakin expensive i use mobil 1 synthetic. STP oil filter factory specs. 5 qts barly tuches the bottom hole in the dipstick sometimes lower then the hole. its a 95 3.4dohc

i jack up the passanger side so i can slid under and drain the oil. do you think that would have anything to do with it?...

im not stuipd i check the oil after getting the car back to ground level.

nope. i wonder if its the wrong dipstick but it looks the same as all the other 3.4dohc moters i have seen

No but for some reason it seems the 3.4 always takes more then neccesary. Mine takes 5.5-6.0, my friend I know had to put almost 6 in!
