Hi BITOGers,

I have been touring this forum for a while now and registered just a while ago.

Since this is my first post, I thought it would be a good idea to start with a dumb question

.

I read in several posts something I have a hard time to understand: Changing the oil filters during an OCI.

How do you do that? will the oil flood when you remove the oil filter?

The only way I see that is to remove the oil, change the filter, and put the used oil in the engine.

Thanks for help me know more about engine and oil, this forum is great.

PS: I have other questions but, I promise, there are more useful (I think).
 
Very little oil will be lost, mostly what is in the filter. The oil is down in the sump and there is no pressure pumping it into the filter. The oil does not drain out when the filter is removed. You just add back what little is lost and are good to go.
 
I always drain the oil pan first,then slowly remove the filter (sometimes I have to use a pair of channel locks to get it off depending on how hard I tightened it when I put it on). When I`m removing the filter,I always loosen it slowly until the oil starts to run down the sides of it and let it all drip into the oil catch pan before I totally unscrew it.

Be sure to have some of those blue paper shop towels handy.
 
On most vehicles the only oil lost is in the filter itself. If you use a plastic bag to cover the filter as you remove it (upside down or side mounted), little oil with cause a mess. I do not change filters without changing the oil. If I was going to go for extended oil changes (> 7,500 miles), I would use a super premium filter like an Amsoil. Any good brand name filter will easly go the 7,500 most manufactures recomend. Yes, I know, some monitors go out [censored], but that assumes very light duty oil service and that would include the filter.

Easy pie. Unscrew the old filter screw the new filter on. No oil flood, no excitement. I used to do it on many cars. At rest the oil is in the pan, not the top side of the engine.
 
There is one engine, a GM iirc, where the filter is REALLY in the pan..that would be the only instance that I can think of where the two are mated in the changing.

There's no reason why you can't do this. It's just more convenient to do it either every time or every other time you change your oil.

WaooH, didn't have time to ask my second question and already 5 answers.

Thank you guys (and thank you for the welcome).

I knew that I learned something today: I thought that the filter was at the bottom, at sump level, that is why I did not see how to do that.

As Gary says, I will not do it anyway (just curious), but the other way around, yes probably, with Amsoil nanofiber filters.

I learned something today (told you I am newbie in oil :) )

Thank you a lot.
 
You need to be careful. For example, when I remove the filter on my Tacoma, about a 1/4 of a quart of oil will seep out around the oil filter as I am unscrewing it. It sucks.

What I do is use a good plastic bag like a giant freezer ziplock bag and put it under and around the filter after I just loosen it a bit. That way, all the oil goes right into the bag. No mess and no hassle...that is unless I drop it and the whole [censored] thing falls onto my chest. (Like that never happened.

Most vehicles I have owned had horizontal filters equipped with anti-drainback valves that always seem to work just fine so even when the oil is drained from the pan they retain enough oil to make a fair mess. I have been known to puncture the filter with an awl and let it drip into the drain pan over night.

The only times I change a filter without changing the oil is upon startup of a freshly rebuilt engine; I like to put a fresh filter on after cam break-in, probably doesn't do any good but it makes me feel better.

Another option is to grab the cordless and drill a small hole into the bottom of the filter. That narrows the mess to a narrow, small stream of oil until contents emptied. Then unscrew the old filter.

Beside at most 1/4 qt of oil between the filter and oil pump, and in the oil pump outlet, the most oil that could additionally drain is in the filter. Depending on the whether the filter is sideways, upright, or upside down will determine if oil in the filter will drain when removing the filter.

Why are you looking to change the filter without changing the oil? If you are not running an engine cleaner (ARx, etc.) that could loosen sludge and other deposits which could clog the filter, a good oil filter under normal use will last at least 2 OCI's. I believe Honda even recommends this filter change cycle. The only reason why I change the filter on each OCI is because my cars are still under warranty and they are not Honda's.

Hope this helps.

I have a 2005 Ford 3.0L Duratec engine.

AFTER I drain the pan...I get ~3/4qt oil coming out of the engine upon filter removal. Filter is mounted horizontal. This not the oil in the filter, it drains out in a stream maybe 10 sec.

Someday I find a schematic of the oil system...
