some of the petrols do that, not really a NZ prob as we have pretty much only diesel Isuzu trucks here, but it's been bitched about a lot in this forum. Try

My engine is drinking oil a lot...no leak...need help
How much is it using? The Isuzu 3.2L V6 engine is known to use alot of oil. Typically it will use 1L per 3,000 miles. You need to keep an eye on it and not let it run low. If it uses more than 1L per 1,000 miles then there is a major problem and Isuzu should repair.
The reason it uses alot of oil is because Isuzu designed the engine with short piston skirts. This reduces friction and thus increases horsepower but allows more oil to blow by.
Oil consumption can be reduced by making sure you are using the correct viscosity oil for your climate. I use 10W-30 but live in a rather warm climate. Others have reported less oil consumption with synthetic oils.
My isuzu dealer makes me put 15-40 oil in my '01 Isuzu Rodeo It's thick and mushy in winter but my old isuzu pickup had over 9 years and didn't burn oil, so i guess isuzu delaer is correct.
My 98 Trooper is still using around 1L per 600 miles, even on 15W-40 half synth. The weird part is that there is no oil burn residue on spark plugs, no leaks, no nothing! What I've done so far is cleaning the engine oil system and putting in seal-rejuvenating additive into oil, have yet to see any difference. Last thing to try is piston rings cleaner...
