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 www.groups.google.com and google this group for "eats oil" and
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 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...
