oil changing device

cas206 · May 24, 2012

I just bought that pump last month and it did a good job on my 2 cylinder 13 hp Volvo Penta. Quick and Painless. So my one experience with it so far is a positive one.

If the pump looks like this: http://www.amazon.com/Mityvac-7400-...JM14/ref=sr_1_2?ie=UTF8&qid=1337911604&sr=8-2 it is the best I have used in 40 years of doing oil changes.

I would not use 3 months as a gudie to change oil. Up north we do it every season. Your engine manufacturer will give you a guide on when to change by hours of engine time. I would stick to that or every 6 months or so.

Those pumps are great. They have couple of different tubes that make oil removal very easy. It is best of the oil is warm. The tubes are made out of a flexible but rigid plastic so the hot oil does not soften them.

They come in different sizes so a smaller one will normally work well on most sailboats (you need to think about storing it).

Simliar products are marketed by Mityvac, Moeller, West Marine and others. Moeller had a 4 liter one that was about the right size for most of us. The ONLY negative thing I have heard about one of these units is the vessel cracked (probably a mfg defect).

I seriously doubt that you need to change your oil every 3 months. I believe that every 75-100 hrs. or once a year is adequate.

I have been using the four quart version of that same pump (previously sold under the Tempo label) for about 8 or 10 years. We change oil at the end of each season. Works great - especially since our Universal diesel holds four quarts....

Greta Pump!! I've been using mine for a couple of years now and it works great on the Engine oil (25HP Universal) and my transmission. Also works great for sucking the small bit of oil out of the outboard.
BTW... Changing oil once per year is probably enough...

One vote for mityvac, nice and clean.

Wow, You guys use a mityvac to change just four quarts of oil !?! I have a Tempo vac that I use for many different uses, but never for used Diesel oil. Once you use it for that application you will never get it clean. I use Jabsco's Handy Pump and a One Gallon milk jug. It is easy to break down and clean.

Mine remains pretty darn clean. In this video it probably had over 30 oil changes, all diesel oil..

Have used them all, but most happy with the Pela oil extractor (mytivac type). Just give the pump a few strokes and the created vacum will pull the oil out of the crankcase. Transfering the oil into a container for disposal can be done outside the boat to avoid any mess. Considering the use the pump and pickup tube clean well and easy enough for storage.

I have a Tempo (mityvac) that I got for my Yanmar 3GM, and I think it was money well spent. I don't clean it, just empty it, and store it in the garage with the tube straight up. Eventually it drains virtually dry. I store the other tubes bent into a slight U so any residual oil just sits in the bottom.

I'm going to try it on my Honda outboard, only because the drain chute makes a huge mess when the oil comes out too fast for it to contain. Maybe if I pull most of the oil out first, it won't make a mess when I pull the drain plug.

If your engine has a lot of angle

If your engine is angled much, you will always leave a substancial amount of oil in the pan if you use any kind of pump through the dipstick tube. And it is very easy to make a hell of a mess. I finally got tired of all the hassles. Pulled the oil pan, drilled and tapped an "L" fitting into the very back of it. Hose and ball valve complete the arrangement. Now I simply put a pan down, open the valve and drain ALL the oil out of it. Will never go back to the other way.

The biggest issue I have is that even after all (or most) of the oil is pumped out, removal of the filter seems impossible to achieve without making a giant mess. Some suggest piercing the filter and draining it that way, but still, it seems inevitable that some (okay a lot) will spill... Not my favorite job. Glad it's only once per season...

You can contain the oil that spills out of the filter by pulling a Ziploc freezer bag up around the filter before you unscrew it from the boss. After the oil is mostly done dripping, zip the bag up and deal with the bag full of oil and filter somewhere else (i.e. off the boat).

There are a few tricks..

1- Poke a hole in it with an awl and drain it into a can with an oil absorbing pad..

2- Wrap/surround the filter in a one gallon zip lock bag with an oil absorbing pad in the bag. Now carefully crack the filters gasket open and let it drain into the pad in the bag, works darn well.. Once drained remove bag and zip it closed.

3- Install a remote oil filter..

I chose the latter...

Big benefit here is more sq in of filter, I used a larger one than the engine had originally, and I added nearly a quart of capacity to the oil system. More surface are and more oil never hurts an engine...

The little pump that could including right out of a dipstick

My motor is installed at a 15 degree incline SO a new hole to remove ALL the oil hass worked out well

sailaway78 · May 25, 2012

I'm with mainszil

A remote filter is next on the list. Even with poking a hole in the filter, I always manage to make a little mess at best, a major one at worst.

JoyRide28 · May 25, 2012

Good idea on the remote filter! In my tiny engine compartment there's just no room to maneuver a ziplock bag. I am going to give that one some serious consideration. Thanks!

Transdapt filter relocation kits

I found transdapt remote filters on Amazon. For the Universal M-25, it matches with a 2004 chrysler sebring. (20mm x 1.5 thread size). I mounted it to the bulkead (similar to MS's location). Makes the filter change a breeze. Using that and the mytivac, I hook up the vacuum pump to a hose off the sump, pump it a few times...have a beer...when it gurgles, I loosen the filter, and then bag and remove it. Reinstall, re-fill, run motor, check the levels then go sailing!

(The beer time is key...no fuss, no worries, no stress!)
