The only thing you are demonstrating here is that you know and use every filthy 4 letter word in the swearers dictionary but are pretty clueless about cars.
For a start you DID NOT buy a NEW car. You bought a USED car from a Holden dealer with 20,000 kms on the clock . So stop raving on about your "new car". You said in your post-
"Currently my SV6 S2 SIDI has used 450mls in 3000k's. I have started an oil consumption test with Holden last Friday 26/10. I bought the car with 20000ks on it from Heartland Holden blacktown, I noticed the oil was low before I paid for it, got them to top it to full. "
If you had half a brain (which from your posts here you clearly don't) you would not have bought the used car in the first place. You saw it was low on oil and should have suspected a problem there and then. At worst there was a significant problem with the car (a good reason to not buy the car) and at best the previous owner was really slack with the maintenance which is also a reason to pass on the car. (Then the dealer was so slack in preparation of the car for sale he never topped up the oil either allowing you to identify the problem).
More than likely the car has been using some oil since new, the previous owner possibly never bothered to keep it topped up and the car may have been virtually untouched until the 15000 km service. Plenty of engine damage can be done running on low oil. You don't know how low the previous owner ran the oil or for how many kms. If the piston rings are abnormally worn for the kms covered due to the engine being run low on oil then the car will burn more oil than it did even when new.
So basically you are a fool for buying that particular USED vehicle in the first place.
I am sure others are also very tired of your rants and now please go with your retarded little brain and promulgate your filthy language somewhere else.
Yeah mate, put in your 2 cents worth. If we all had crystal balls eh?.Pity you don't have anything constructive to add. Like I said, to me, it is like a new car, only I did not lose 8 grand when i drove it out of the showroom.
I started this post because I wanted to know if others experienced oil consumption, there was not much info out there, and also to find out what Holden where doing about it.
If you feel this post has no relevance to you, great, move on mate. I chose this particular car because it had low k's, in excellent condition, log book was filled out correctly and previous owner, well it was a Holden Execs car, had not been registered to the public before, same as the VY I bought. Anyway, if people are OK with their vehicle burning oil, that's great, good on them, but don't come at me with oh its just oil mate, dont be a tight ass etc etc, because I for one do not find it acceptable, and I have every right to get to the bottom of it, who knows, I might even get a fix out of Holden for it. You see, I like to have a reliable vehicle, with no issues, if I find an issue, I fix it, and as the car has warranty up the wazoo, I will get this issue fixed one way or another. Also, as for your comment about my intellect, I think that you have displayed what your intellectual capacity is and YOU don't have a clue, I bet you call roadside assist when you need to change a tyre. Oh and look, I did not even swear :] you are soft sean880. So if you don't have anything relevant to add to this post, you know what you can do.
