Oil pump for oil changes??
 

Any suggestions on oil pumps for oil changes, I once had the drill pump and that was a joke!! Been looking at the ones from overtons that are electric diaphram type with 3.5 gal capacity. I want to buy a nice one! Thanks for any info!

The vacuum pumps work fine. They take 10-15 minutes longer than the electric pumps, but they do a fine job.

Just spend at least $40-50 on one. The $20 jobs don't seem to work well.

This is the one that I use:

It takes about 20 min. per motor, and I have to pump it about 3 separate times to finish the job, but it works well.

i bought one with the 12v electric pump takes 2 or 3 mins to remove oil has a switch to reverse flow for disposal it was around 100 bucks. makes oil changes somewhat enjoyable.

I use this one, http://www.wholesalemarine.com/p/PEL...LAID=662761908 works well, found it works best if you use the dipstick tube as part of the suction line instead of sticking the smaller tube into the dipstick. Sucks out 11 qts in 15min.

Bought a small 12v utilty pump from Harbor Freight for $30 or there abouts, works like a charm. Connected to an oil drain plug hose and can pull the oil out in a min. when warm. Mount it to the lid of 5 gal bucket, with the outlet discharging into the bucket. When full, just remove the lid and pour it out. No mess.

us1 fountain....are you pulling it out the dip stick tube?? do you have to prime this pump?? Overtons had one but it had to be primed or it would just burn up.

I originaly tried that, but it took 10 min or so because I used a small tube to go inside the dipstick, which made for a very small ID. Worked great when tested with water. Pump got really hot trying to pull oil thru that small of a hole. So that setup was scrapped. A buddy had the 5 gal setup and has been using it for yrs with no problem, so I'm coping it. Never have had to prime mine yet, (lack of use?)but my buddy has his a couple times. But if that ever arises, I'll just pour some water or oil in the hose to prime it. Mine has the vanes that move outwards with centrifrigal force, so more likely to stick if not used enough. Hense the cheaper price, but for 1-2 times a yr use, I'm ok with that. The rubber impellor pump type should work no different than your seawater pump and not need primed.

The electric impeller style pumps, in my experience, SUCK. If you run them dry for more than 30 seconds or so the impeller is shot. I was buying decent quality pumps too (pumping water with them). Maybe the ones built for oil or other fluids work better?

Pstorti - If I had high capacity oil pans I would have definitely gotten that system. It's a nice set-up and worth it if you do more than a few oil changes a year, or if you have an oil capacity of more than 8 qts.

Just don't get this style:

Or this style:

Or you'll be pumping till your arms wear out... Kind of like putting drive lube in with the hand pump...

us1 fountain, I just got off of harbor freight site and found a marine utility pump for about 30 bucks, seems to be the same as the other system out there, vane pump, self priming....Even has mounting tabs so i can mount on top of 5 gallon bucket. I'll probably go that route and make my own. Should work just fine for one oil change a year!! Thanks

the other electric pump systems use the same small tube and suck through the dip stick tube...im gonna try that. Pump specs will lift fluid up to 30' surely it should suck hot oil up 3'???

Probably the same one I bought. General Machinery? ?They had 2 pumps on the shelf, both looked exact same, just in different boxes with one labeled as marine pump. Mine says 35' head height, self priming. I just didn't have any luck with the small tube, even with the hot oil and the tube cut as short as possible thinking I had too much resistance at 1st. I could have sucked it out with a straw faster. I installed a switch on the pump handle to turn off/on for ease. As I mentioned, if you could get a hose at the oil pan drain, it'll be so much better, plus it will get all the oil out. I'm afraid you'll be dissapointed trying to use the 'hose down the dipstick' with that pump.

I use one from west marine that is on a bucket and sucks through the dip stick.

12v works fine. Next time I pull the motors I will install a hose from the pan, that is the best way to get all the stuff out.

i bought the pump today, its by pacific hydrostar. Marine utility pump 200gph. I already have the small hose that goes into the dipstick. Gonna try it out. Looks like a nice pump. I don't know why this will not work, its the same principle as all the other suck through the dip stick pumps??? If not i'll just buy the one that is mounted to the bucket, by sur-flow. I wonder if you can buy one of those pumps that are on the "oil change systems"?

Old thread I know but it definitey helped me out and saved some $$ so worth a bump. I just picked up the 12v pump from harbor freight and mounted it to a bucket. Both motors are on stands right now full of dyno oil so I just screwed the hose to the hose adapter on the dip stick tube. See pic. I had to change to a reinforced hose to keep it from collapsing. This method left quite a bit of oil due to the angle of the motors on the stand so I will still connect hoses in place of the drain plug.

I know you said that you wanted a pump. However, what I have and used is the drain hose that connects to the drain plug. I can get the oil as hot as "satin's nards" pull the plug and proceed with a nice long drain. It was a challenge to get the hose connected to the drain port but it was well worth the effort.

I have two motors so to fish the hose down through the drain hole one at a time would be a pain. I'm still going to use the hose method but just to the end of the pump as well.
