I am considering using one of these vacuum pumps for oil changes:

inserting the plastic tube into the dipstick tube seems easier then getting under the vehicle, undoing 8 bolts of the protective plate, and then drain plug - anyways, should be easier done from the top in winter months... |

Interesting. I've always been wary of using vaccum pumps when draining oil in case i can't get all the black stuff out. I once saw a car straight from a dealer (not L/R) after oil change using a pump and the dipstick was covered in black streaks. I assume the worst of the oil is at the bottom of the sump.

So.....do a lot of dealers suck the oil out rather than let it drain out then? To be honest, even draining with a flush rarely gets all the sludge out, so actually I can't see the problem with the suck method. You can measure the quantity taken out to know your about there and as said, it's got to be easier when doing it yourself. I suppose, no sump plug washer to buy either. |

Thanks for reply, superspark-what is the oil capacity of your disel engine? my 3.2L takes about 7.5 L of 5W-30, I guess I will have to try the vacuum method to see if I can get most of the oil out, since the 3.2L gas engine is uncommon in Europe... |

Hi m1964, I had sucked out five litres or there about and after removing the sump plug got out about another litre, the book if i remember states 6.5 uk litres but that would be a dry engine. Fuel here is very expensive, where i buy it it is £1.16.9 per litre. |

Ah, I looked yesterday at the reviews/ratings of those Vacuum pumps, and some people reported that the seals in the pump start to leak if using synthetic oils-the pump does not leak on the first use, but after one -two months they leak oil. back to my independent mech next week -oil filter and mobil1 already in the garage. Thanks to all for your help. |

This type of oil change is only effective if the dip stick hole is over the lowest part of the sump. Older in line engines almost always had this configuration but there is no guarantee and this is why you cannot get all the oil out of the FL2. If you can argue the cost vs convenience do the oil change warm as has already been said but do it more often than required by the service intervals. Prog rock is cool!
