Title: Omega Oil Consumption
Post by: amba on 14 September 2012, 09:42:53
Never really paid much attention to data in back of manual for Omega from VX but last night wasting time between jobs and was rading through manual.

It states that oil consumption per 1000 miles is 2.12 pints ,,so in round terms just over a litre.

Now if an Omega hold 5.75 litres of oil from empty sump/oil filter if you didn,t check or top up oil within 5000 miles which is there recognised service interval for oil changes ..the car would be out of oil  ;D

Does an Omega really use that much oil...I tend to get low oil check normally twice between my standard 3000 mile oil changes and when I inspect dipstick it has dropped by only 1 increment on metal markings so that is less than 0.2 of a litre assuming markings from top ..full  to bottom /low is 1 litre as book states.

I cant imagine my car is really much different from all the other engines so why the wild exaggeration on oil consumption by VX then ?

I think it's the extreme worst case scenario and marks the point where they'd consider fixing it under warranty. ;)

1 litre of oil every 1000 miles is quite excessive and think you would have a car belching out some serious smoke let alone state of engine bay,

Good old VX  ;D

Although not common for a modern engine, it's within what many manufacturers consider acceptable. It doesn't include leaks! It's pretty typical on twinspark Alfas, and they have tiny sumps. I've picked up several with knackered engines where the driver has sheepishly admitted to not checking the oil. Most of those conversations also included the phrase "I should have known better."

I suspect that it's due to the really thin oil used in modern engines. After all, 5w30 used in V6 engines is pretty thin, and 0w30 is hardly uncommon.

It's a get out clause IMO. Which they do use to their benefit. That being not accepting a warranty claim due to excess oil loss, as they can point to a rediculously high consumption spec. and wash hands of the whole thing.

Although it should encourage owners to check their oil regularly I suppose.

My beloved MV6, if I rev it hard, needs a top-up halfway through its 3000 mile oil service inteval. So it always gets half a litre about 2000 miles after its service ::).

But no blue smoke ;)

VW PD engines do use this much oil, especially if they've been a bit neglected ::) Not really surprising then that the camshafts wear out after about 150k :-\

I dont remember ever having to top mine up between services. Same with my old p/fl 2.5 until it started leaking between the bottom of the block and the top of the alloy sandwich between the bottom of the block and the top of the sump.

I tend to stick about 1ltr in mine every 1000 miles or so.

As TheBoy says, it all depends on how much playtime it gets  :-X

Starting to get a little blue smoke when its been idleing for a while then you pull away.
Seems worse when the oil has been in there for a few thousand miles. Give it a oil change and it settles down for a couple of thousand miles.

The engines done around 140,000 miles  :-\

Amba,

Are you sure it's 1,000 and not 10,000?  :P  ;D

He was right. None do use that much though.

All data was from the car manual,as I had time on my hands and nothing better to read..sad I know ;D

Just struck me as excessive for even the manufacturer to state such high oil consumptions were what appeared to be the norm

I recon I put in less than 0.5 ltr between oil changes of 3k..manula recons I should or could ?? which ever whay you read it ..be adding 3 ltrs :o :o :o

depends on how hard a car is used, if with my 2.2, I did a months worth of commuting (near 1k) of cruise control set at 80mph, did not use a drop of oil.

But do 90+ runs, and it started to use it.

That's just Vx covering themselves for oil lost into spark plug wells and dripping onto exhaust manifolds.  :y See, we thought that it was an error - but it looks like it's a design "feature".

Interestingly - some years back a few chums who had Audi company cars were basically read the riot act on delivery by the leasing company. Along the lines that if engine failure was caused by lack of oil that the customer was liable. The Tdi engines used oil, and they were getting through at least 5L between services. Makes you think twice about buying a used VAG product as the majority of drivers dont check oil from one service to the next ............
