Bigger Than Stock Oil Filter
 

ok a buddy of mine uses oil filters that are larger than the stock size but the threads and gasket are the same size I have thought of doing this as well but not sure if there could be any problems with doing this.
dose anyone else use a larger oil filter on their trucks?

I use a larger than stock filter on my 5VZ. I think there are quite a few people here that do.

I tried with my 3.0, but there wasnt enough room to get a larger one in there. I think youd need a relocation unit to do it.

Do a search on oil filters--you'll find plenty of information. What I gather is that you could have a considerably harder start with a larger filter.

for my 5VZ-FE (3.4L), i use a filter for a 1995 3.0L Taurus. yes, for a FORD.

i personally like the NAPA GOLD filters. good stuff, easily found, and affordable.

3.4L Toyota Filter Specs: (according to http://www.napaautoparts.com)
3.0L Ford Filter Specs: (according to http://www.napaautoparts.com)
the ford filter is $0.20 more, but has 50% more filter media...

now check this out! your 3.0 takes the same filter as the 3.4. that means that you can also use the ford filter.

however, you still need to check to see if it will physically fit into the spot for the filter.

another interesting fact is that the 2UZJ engine in my UZJ-100 Land Cruiser (V8) takes the same filter as the 4Runner, which is a prime candidate for the larger Ford filter since it also takes quite a bit more oil. the more media, the better...

the idea is to look at your filter side-by-side with other filters of the same diameter. find on that has the same gasket diameter and same thread diameter/pitch, but with more filter media (overall longer).

a good place to do this is acutally wal-mart.

From what I understand it's not a good idea. Not good on cold start, oil doesn't get up into the valves and cylinders as fast as it would with the standard size filter.

not true with current quality filter designs. most - if not all - will have an anti-drainback feature. they hold oil in the filter when the engine is off. as soon as oil reaches the filter, then oil leaves the filter - by simple displacement - so there is no change in effective time for the oil to reach the most remote passages in the engine.

Not only that but if ford uses them on their cars they are working fine.

It would be pretty funny seeing a group of ford engineers in a room going "wow, these cars keep blowing up on us - that's the 4577th one this week. I wonder what the problem is... "

I've seen several dual filter kits as well as the relocation kits that also add capacity. If it were bad there wouldn't be so many using them.

Thanks for the info... I'll look into using one of these on my 22re...

From what I've seen in the book (even though I don't use them) Fram, recommends the 3614 for every toyota motor I checked including the 22re, 3.4, and the 4.7. If it fits one it should fit all if there's room.

What is the difference(s) between using a stock filter and a bigger one?

Whatever you do, dont use a fram. Sure people use them all the time and done have problems, but they have a very low quality filter media, bad mojo for engine bearings. You already know that but just to reinforce it.

I run a much bigger filter on my 22r. It is a fleetguard LF551A. I could seroiusly fit two or three 3614 in that filter. I'm a mechanic a diesel truck shop and I got the filter from our parts department, but I think you could probably get them elsewhere. Fleetguard makes an excelent filter, the're designed for commercial applications which go much longer between oil changes. Thus, their media can hold much more contamination.

One thing I did notice was that cold startups took a little longer to build oil pressure than usual. Just pumping more oil.
I do have better oil pressure after the filter than with stock, larger filters flow better.

Two benefits:

1. Increased oil capacity. More oil = more life and marginally cooler.
2. Increased filter surface area. Better flow through the filter and takes longer to clog up.

Both serve to increase oil longevity.

One (possible) drawback:

1. Longer time to reach operating pressure if the drainback valve leaks by (and all do to some degree).

FWIW, I run dual NAPA Gold 1773 filters that hold a combined three quarts of oil just in the filters. If mounted properly (open end up) with a remote mount, once they are filled with oil, they cannot drain back regardless of the quality of the drainback valve. Just keep the supply line as short as possible or locate the filter lower than the block fitting since this could very well drain back at every shutdown.

yes all antidrainback valves leak, but the purolator (motorcraft is a rebranded purolator) tend to seal well. Frams do not. I wouldn't go compare filters at walmart because from what ive seen all they carry is a giant wall of fram crap.

A really good, and informative piece on oil filters, where a number of filters are actually disected, and compared.

all i was saying is that i compared them at wal-mart to find the right one, then cross referenced it back to a vehicle that it fit. then when i go to NAPA, i ask for a filter for a 1995 Taurus with a 3.0L engine and i get the correct filter that fits my runner, but with ~50% more media. ;)

wal-mart allows you access to the filters so that you can actually open the boxes and compare them before you buy them.

true, so do a lot of autoparts chains. I know for a fact that advance does.

The numbers from NAPA are:

Stock: NAPA Gold-1348
NAPA Silver- 21348

Higher Capacity: NAPA Gold- 1515
NAPA Silver- 21515

A 1515 is a Ford filter used in V8 trucks, the threads are the same and you will have 1/2 quart more capacity than stock. Stock= 4.5 quarts.

I believe the napa 1515 is the same as the motorcraft fl-1a for people without a local napa. I believe the napa 1515's are a little more expensive, but both filters appear to be well made

I use FL-1A on my 22RE's. The filter itself holds a quart of oil.

I did an oil change on the 4runner today and used the ST16 filter (Supertech from Walmart, made by Champion) and it fit great and added about 3/4 of a quart capacity to the oil.

I feel a lot better about having that on there than I did the 3614. It's so much bigger.

I can't wait to get one on the 22re now. ;)

I use/have used a ford V/8 filter on all my 22R's and 22RE's had 390,000km on my '82 SR5 when I sold it in 1989..filter is a tight fit on my 92 but it does fit. Adds 1 quart additional oil capacity.

I love my toyota oil filters, if i cant get a toy filter free ill buy a napa gold.
