hi bruce
i personely believe that the cause of these vehicles developing hi oil usage and toyota aren't alone is because they dont have any load on them when they are running the motors in causing them to glaze the cylinders and once that happens its the pre-curser to high oil consumption
years ago engines were hardly powerfull enough to propell the vehicle along the rd with your family in it and that in itself would put enough load on the motor to wear it in
but these days they have such high engine power that just driving around empty or with a couple of passengers is whats causing the glazing of the cylinders resulting in oil usage problems just down the track
imho anyone who buys one of these high output engined vehicles whether it be petrol or diesel needs to put a load on /or behind it from
from day one and just drive it steady for the first 2-3 thousand k'
this will insure that the motor wears in and the longivity of the engine will be rewarded
when ever we bought a new truck in our farming days we would buy it before harvest so the engine wore in unload we did on one occassion buy a new truck in the off season which didnt really get run in with much load and it glazed up and started using oil after only 35-40thsn k's
we finished up pulling it down and honing the cylinders and fitting a new set of rings then running it in with loads at harvest time and had no more oil problems which was proof in itself
there are so many owners out there now buying these big engined 4x4 now that dont have any mechanical knowledge and just use them for lite duty short trips and shopping taking kids to school etc
or just go on a trip with no load and in my opinion that has a lot to do with the problem
i expect my opinion to be contradicted as thats par for the course on here but then that's a healthy discussion
cheers
