I will still be using full synthetic and I will not leave the same filter on for more than one oci. Does anyone know the efficiency of premium guard or eco guard?

With the products you are using, you should easily be able to go 6k-7.5k miles between oil changes.
 
My problem with leaving the filter on is not getting all the old oil out of it. I'm the kind of guy that pulls the plug and comes back and hour later. Why would you want to purposefully leave old oil in there?

Also, nobody asked the op what kind of driving he does, short trips, long trips, just automatically recommended longer changes. If it takes him a year to do 3k and it's doing short trips then he should definitely change it at that point.

How much oil is it using? Half a qt? 2 qts?

Spending more to get higher efficiency isn't the same as spending it to have a longer life oil filter. I buy the higher efficiency filters because my engines are 42 and 36 years old and I want them to keep going for many more years. It should have more to do with how long you are hoping or expecting to get out of the vehicle.

With the service you are doing I would run Supertech HM synthetic with a ST Filter - all at Walmart and would cost you under $20. Its a good oil and the filters are not bad either.
 
So I have two that hold 8 quarts but I know pulling the filter takes a quart. If I'm like lots of conservative folks here and run 5k OCI … leaving that quart would not bother me as far as oxidation or TBN every other OCI with a better filter.
Different things worry different folks. I think of DI dilution, so will use a good low cost filter as a means to spill and fill a quart, top up with thicker oil, and get another 50% from the oil for $7. I feel better going down near 0 on the OLM that way. Doubt I'd do that if it were not easy, but it's very easy on my 4WD's.

It burns close to a quart in about 2,700 mileswith synthetic blend. With full synthetic it gets about 3,500 before it burns a quart. It is my secondary vehicle that doesn't get driven as much. I would say 3k in about 4 monthish.

I guess if it was me I would probably top up to full at 3k miles and run it to 4-5k or 6 months roughly with synthetic and a decent filter.

With my own truck I'm getting a lot of short trips from site to site, some longer trips. It uses about the same amount of oil as yours, 200k on the truck. Last time I went to 12% oil life which was 6 months 3k miles. That was including the winter which drops the oil life way faster. I just switched to qs synthetic high mileage and a fram ultra and I'm going to likely run it closer to 0% next time, depending on how long that takes and if it's almost getting to be too cold out for enjoyable oil changes.
 
Are you going to decide this on facts or feelings?

Facts indicate what you're doing is overkill, but doing less makes you feel like you're not doing everything you can.

End result?
The filter doesn't ever get close to being plugged - - **IF** you do regular oil changes. ...
That's consistent with what I've seen---with the further stipulation that I, like apparently Linctex, was not doing many very short trips.

Because the residual oil in the filter (especially if you drain it) is not as significant you imagine, and some old oil is trapped in other places in the engine anyway. You can compensate for the resulting slightly older "average" age of the oil by changing slightly earlier the next time.

Honda recommends changing the oil filter ever other OCI ... but what do they know, lol.

I could see worrying about leaving the filter on if there was 10,000+ miles on the oil, but the OP says he changes the oil ever 3,000 miles, so I doubt that oil is anywhere close to worn out since he say he's using full synthetic oil.

3K miles in 4 months isn't barely driven. If it was 3K miles in 1 year then that's what I'd consider barely driven.

I'm just not one to push the oil to the limits. Why use oil until it's on the verge of being bad? I understand 3k is short for full synthetic. But why top of when the oil is 3k miles warm already? I was hoping more for input on if anyone knows any filters that are a little cheaper than the extended performance ones with still the 99% filtration at 25 microns.

Full synthetic oil isn't worn out at 3K miles. Tons of UOAs prove it can go way longer than 3K miles.

Fram orange cans are rated at 95% @ 20u (and rated for 10K miles), so would probably close to same as 99% @ 25u. Regular WIX and NAPA Gold filters are also 95% @ 20u.

Gm said the same thing back in 1983 in my Caprices owners manual. It doesn't mean it's the best thing to do. Did gm really want my car to last 36+ years? No they didn't.

I don't disagree with you that he'd be fine leaving the filter on longer, but FACT is he sounds like he's trying to maintain it as BEST possible and lots of people in this thread FEEL that the oil should be left in much longer and the filter should be left for 2 oil changes. MAYBE it would make no difference in longevity at all, MAYBE it ends up using more oil over time or develops a lifter tick or something. Maybe it lasts until 250k and could have gone until 400k...with more frequent oil changes. Every vehicle is different and you can't say for sure that your way is right every time.

Working in garages over the years for every vehicle you tell me went 10k oil changes and lasted 300k miles, I've probably seen a couple that were treated the same way and had major engine issues.
 
Not to mention synthetic doesn't change how much fuel dilution is in my oil or moisture from short trips in extremely cold weather.

Thank you for taking the time to type what I was too lazy too lol. I have been think and it would probably make more sense to use a 10k rated filter and swap it but after 2 oci. It would still be getting 99% for the 6k miles versus a 95% even with a new filter. Just goes against my nature to leave something on when I can swap it out easily. Still might just swap out for sale of mind.

If the OP wants to feel like he's doing the best he can to keep the vehicle in good shape with oil and filter changes, then he shouldn't worry about the cost of oil or filters. The focus seems to be on the cheapest filter he can find with the highest efficiency for the price.

If I was doing only 3K oil changes, I'd run an Ultra for 3 OCIs and it would be costing me $3.xx per oil change and would only be used for 9K miles which isn't even half of what it's rated for.

OP is driving 3K miles in around 4 months ... doubt it's all short trips. If he's so worried about his oil then he should send in a UOA to see how the oil is holding up in his driving situation.
 
A used oil filter will have higher efficiency of filtering smaller particles than a new filter of the same filter. Once the old filter becomes partially blocked it filters better. If you just have to do an OCI every 3000 I would at least run the same filter for 2 or 3 OCI'S since you are wanting a more efficient filter at a lower price. The Ultra run for 3 OCI'S world cost just over $3.00 per 3000 miles and be about as good as you can get.

There is info out there (from M+H/Purolator) that says that's not necessarily true. It might be more true for air filters, but not so much for oil filters because oil filters experience way more delta-p across them than air filters do. As the delta-p increases on an oil filter, it can dislodge already captured particles and send them down stream which decreases the filter's efficiency.

Best practice is to not run oil filters more than what they are rated for.
 
For 3k runs I wouldn't spend more than fram orange or supertech. Or like others have said run fram ultra multiple OCIs.
