If you want to extend your time between oil changes, running a great full synthetic oil such as Pennzoil Platinum or Ultra, Mobil 1, Valvoline SynPower, German Castrol, etc. is not enough, you still have that wimpy little oil filter than doesn't have the capacity to go 12 or 15K miles! - Even if you are very conservative in your oil change frequency and change it every 3000 or 5000, a larger and better made oil filter is never a bad thing!

So here is a list of the most premium oil filters that work great on all LS models from 1990-2006 and give you ~60% more volume as well as premium features on the inside of the filter such as a silicon anti-drainback valve and high quality bypass valve of the same PSI setting as the stock Toyota filter.


here is the list of the world's most premium oil filters, in oversize, which I can expand if I have missed your favorite brand:

Motorcraft --- FL-400S
WIX XP --- 51516XP
Fram Ultra --- XG3600
K&N --- HP-2009
Mobil 1 --- M1-209
Bosch Premium --- D3422
Purolator PureONE --- PL20195
NAPA Platinum --- PFL 41516
Amsoil --- EAO34
Royal Purple --- 20-400
Toyota (NipponDenso) --- 90915-20004 (made in Japan) - this is the filter than came on your car when new, hard to find now
TRD (Toyota Racing Design) --- PTR43-00080 .....Note: this is not an oversize filter


PS - the K&N and Mobil 1 filters are the same filter internally, and with minute differences the Royal Purple and Toyota Racing Design (TRD) are as well, all 4 made on the same assembly line by Fram subsidiary FRAM Filtration (aka Champion) although the filter media on these 4 is not identical.

the Amsoil and NAPA platinum are essentially the same internally as the Wix XP who manufacturers them, although Amsoil is transitioning to Champion (FRAM Filtration) for their manufacturing.

I am running a mobile 1 m1-209 now. I always research what bigger oil filters will fit with any car i buy.

I'm not. But I think I will start. I've been running full synthetic since I bought the car, but didn't think about a bigger filter. Thanks for the post!

diamondave

I've been using the bosch distance plus filter from walmart and mobil 1. One stop.. for oil and filter. I've put on nearly 30k since last march. used mobil 1 0w-20 a twice. The car has been on normal mobil 1 all its life.

It would be good if installed after filling the engine oil before start to use. Also it should have a valve which prevents the draining.

The empty oil filter needs to be filled with oil when start to use. The engine runs without the oil while this. The bigger capacity needs additional time to be filled and the engine is thirsty while this.

The genuine Porsche oil filter has a valve inside to keep the oil not to drain while engine is off. I always was in use of the genuine oil filters for my Porsche. I am doing the same for my Celsior.

but are you using the oversize filters that I mentioned or standard size?

LScowboyLS

all of the filters I listed have an anti-drainback valve

the orientation of the filter (upside down like RX-7 or rightside up as some other cars are, or sideways) determines whether it can prefilled, most cars can't - on a car with a filter oriented with the hole upwards, it is easy and probably not a bad idea!

dengman

standard size. If walmart carries the oversized filter i might give it a try. If not I wont go out of my way to use a larger filter.

another advantage of using a larger filter is you will have more oil in the system which means more lubrication and oil also acts as a coolant which means your engine will run a few degrees cooler

Walmart carries my favorite oversize LS400 filter, the Fram XG3600 ($8), which the crazy oil geeks at the world's largest oil & oil filter forum, Bob is the Oil Guy, seem to feel is the best oil filter money can buy.

I think Walmart may also carry a couple of the others on my list, I will check next time I am there.

you engine internal temp is controlled by the thermostat, the ECU, the engine coolant temperature sensor, etc. - it will not run cooler, nor should it.

i Run Mobil 1 full synthetic in everything i own. It is the #1 rated oil in the world. Amsoil use to be the best but Mobil 1 passed them a few years back. LS i usually agree with everything you say. I follow your posts like they are scripture but i have to disagree with you on this one. I personally cant stand fram anything. I have done alot of research on fram and they have had several lawsuits due to their faulty filters.

As well, do an oil analysis. If this isn't done the discussion is academic, then you can determine the results on your own car. $35/per with TBN from Blackstone but if you do a pre-pay on 6+, you get a nice price break.
