We just did a six month interim service today on our 2006 3.0 TDi Range Rover Vogue, used the extractor pump to change the oil, wish I had owned one back in the day! Immaculate change absolutely NO oil spillage on the driveway or anywhere else, possibly the best £40 that I have ever spent of vehicle service gizmo's. Of course being an old RR it had to provide some 'entertainment' which it did in the form of one of the hex bolts on the air cleaner cover refusing to be reseated, but apart from that all good. Old oil filter was grim looking as was the air filter, real PITA changing the 'Elephant's tusk'! I use semi synthetic oil on the old girl which seems a happy medium but am amazed at how crap it soon gets to look when checking the oil levels, will probably do a full engine flush next service just to be sure.
