Holy smokes did AC Delco change the size for LS1's again.

The PF46 is almost the same size as the PF47 I use on my Z24.

 

??? The LS1 oil filter has always been small? I run the truck filter to bring the capacity to 6 quarts even...

 

I just thought it was bigger.

What is the larger filter size #?

 

You should have seen the one in my old Honda Insight...My lawn mowers was bigger

 

there is no truck filter.
all ls based motors use the PF46

 

I think he was referring to an oversized filter that happens to fit on the LS1 and raise its capacity. I am not sure what part # it is though.

 

OHHHH yeah... the ***PF59*** I have on my car RIGHT THIS INSTANT is just a figment of my imagination. Silly me!

 

according to GM(close friend) all years and models came with a pf46.
i saw how small the pf46 filter was and wondered. i get them for free, so ill just stick with the 46. its good to know there is a bigger one out there. i was for sure the 4x4 6.0 trucks would come with a bigger filter, but my buddy told me they were all pf46. heck he could be wrong.

silly you.......

ACDelco lists PF59 for 99-02 Trucks with 4.8-6.0s

 

 

 

I use the longer Mobil1, M1-206, and fill it with 6 Qts.

owned? thats funny. i was going off the info i had been given by someone else.
people make mistakes. i should have researched the matter rather than ask someone.
ill still stick with my free pf46, rather than abuy a filter anyday.
i might try and get some 59's if he has any.
