Todd, on their webpage, it was mentioned it won't work on dry sump system (348, 355, and "late" 12-cyl. models).

Saw this on another forum relating to the liquidvac and sludge:
If the oil were cold this would potentially be a problem. I've learned from many that the proper way to change oil using an extractor is to first operate the car until hot. By driving the car and heating the oil your doing two things.
1. Lowering the viscosity of the oil making it easier to remove.
2. Dispersing any settled sludge/solids into the oil so that it can be removed using the extractor.
IMHO any sludge that doesn't disperse from the oil pan during normal driving will be too thick to flow from the drain plug as well.

As an alternative. At kragen, I picked up a siphon pump for $12.00. Came with a hose that you can use to stick in your dipstick slot to siphon oil. Only you've got to provide your own oil container for it to siphon into.
Haven't tried it for oil changes yet.

I just bought one and used it. Seemed to work well. My plan was to do a conventional oil change every couple of changes like Hans suggests. In theory, if the oil is warmed up properly, the "crud" is in the oil, and should come out no matter how you do it. The sludge that is stuck to the oil pan ain't coming out no matter what you do.

Most of the tests done show that it removes pretty much all the oil...even if you leave a quarter of a quart, no big deal....shoot, I put in 9 quarts. It is the possible sediment that might worry me. I know when I removed the oil pan on my old Rabbit many years ago; even though it angled down to the oil plug, there was some sludge along the bottom that I cleaned up. Just seems that it might get worse using the extractor. But, if it just collects a bit at the bottom of the pan, it really shouldn't hurt anything. At least in my un-expert opinion.... |

It's a hose that you snake down the dipstick tube. In theory - and probably true - it sucks out essentially all of the oil. Now, remember, that even with the drain plug out you will probably not get ALL of the oil out, especially if the car is a little off-level.
I was skeptical about how much the hose removed, but adding 9 quarts of oil brought the dipstick right to the same spot as when draining with the pan plug. So....?????
Anyway, I alternate. |

I don't use it. I worry about stuff potentially left behind...but I admit the idea of not having to lift the car and crawl around down there is getting awful tempting...I think Hans is on to something there; but I would drain it the "traditional" way, every third time, as I am one lazy bastard! |

Some - probably with good reason - question LiquidVac for possibly leaving "crud" (techinical term) in the oil pan.
However..........
I do every other oil change with the LiquidVac. Just covering all bases. Filter each time, of course. Only the best that K-Mart offers. OK, just kidding. I use Baldwin. |

Dave (Handa), thanks for the link to the aforementioned (www.expensivecar.com). Wow...
it certainly makes oil changing (and other fluid changes) a breeze and simple, esp. for the "technically uninclined" like me! And I can actually change coolant fluid with it?
Any F-chatters using this? (No offense intended
esp. to Carl Rose who wrote the 328 oil change article); I am just very curious about the product). |
