chewing thru oil

[ryan86]

hey guys i got a 99 vs 5L ute and it seems to go thru engine oil, i changed the oil and filter bout a month or so ago and since then till now i have had to top it up and will need to top it up again kinda soon, its not leaking any where or blowing out black smoke so is this normal for a v8 or have i got a problem with the engine, cheers for any help.

anywhere up to 2L per 10,000km is normal

[ryan86]

i would say it probably chews thru more than that over 10,000km

Wow thats a lot. My 5L doesnt even use 250ml over 10000kms.

Worn rings or valves maybe?

The time to be worried about oil consumption is when they blow blue smoke out the tailpipe when you hold the revs at 2500 for about 1 minute on a warm motor......or they leak oil. Otherwise anything up to a litre per 2000km would be OK with me.
Thicker oil will reduce consumption.

You might of used the wrong oil for it????

[ryan86]

nah i doubt i used the wrong oil, i used the castrol GTX3, went thru there booklet thing and thats what they reccomended

GTX3 is 15w40 which is a thin oil - you should be using 20W50 which is what the manufacturer designed the engine to use - that's what the owners handbook says...... Castrol may say to use it but I'd rely on the people who made the car! Use of a thinner oil will increase oil consumption.
