How many quarts of oil in a 3.1 V6 do you put in when changing oil. I usually put a little less than 4 quarts in. Just wondering what the EXACT recommanded amount is...

 

I believe its around 4 quarts.. although that is pulling it out of my head... i might take a look at my repair manual after i get back today

 

I put 5 with the big fliter, and its a bit much.


So I'm going to say 4.25 with reg filter.

 

4.5 qts.

Just put 5 in tho... .5 qts won't hurt

 

big filter??? part number please?

Why are you using a bigger filter?

you sure about that many quarts in a 3.1 V6? I was thinking more like 3.75 or something like that... the engine shows its full at less than 4 quarts.

 

just did my 2.8 today, put in 4 quarts with the bigger filter and its full on the dipstick. i plan on checking again before i start it up, cause that doesnt seem like enough oil, but whatever.

edit: gm service manual for an 89 says 4 quarts.

 

alrighty. but whats with the "bigger" filter? You mean longer? Now that i think about it there was a shorter filter on the car before i bought it...

 

PF52 filter is the one they are talking about, longer than the stock filter. Holds almost 1 quart.

I never paid attention to how much I put in, I always get the 5 quart jug, and check the dipstick after dumping half in, then just keep topping it off til full. There is always some left in the jug...

 

oh. i've been using ph3980, i think? The one that was on there before before i bought it was 1/2 the size of that.

So theres a small, medium, and large oil filter. just like mcdonald's fries...

 

The PH3980 and PF52 are the same size, just different brands.

The stock filter is a PH3387A or PF47, much smaller.

 

yah the ph3980 is fram, thats the one ive got, not sure what brand the pf52 is.

 

pf52=acdelco/gm

 

For me, I've always tossed in four quarts.
"Some" leaks out anyway thru gaskets.
Always used the AC Delco PF51 until "they" changed over to the PF52, AC Delco brand.
Never knew there was a "smaller size" filter.

 

maby your gaskets not mine!!

 

I'm redoing my covers & gaskets with Fiero covers shortly.
Adding a bit of oil every now & then is way more simple than changing those gaskets right now.
I already tackled the timing chain, rear main seal, rear cam seal, oil filter housing gasket & distributor gasket.
If ya wanna come on by & do the job for me, tho, no complaints from me!

 

I awalys use 5 qts.
