but what about the engine rattle between 1500-2000rpm you experienced? I ask because I am experiencing a rattle between the rpm range, but on and off experience the oil consumption as well.. currently, the rattle is at its worst, but hard for me to determine if my oil is being consumed due to weird readings with the dipstick (that issue has been brought up in another thread).
also, how did the dealer determine you consumed 2qts in 1200 miles?? the dipstick only measures 1-1.5 qts... it must have been bare metal when you took in for the oil consumption results. Can you verify if the dealer marked the dipstick as the TSB states? i had one dealer fill it past the upper notch (nearl 1/2 inche over) and not mark the notch as expected. of course when i took it back, the claimed "oh its at the full mark level, your rav4 is doing great and not consuming any oil". Since then, i have to redo the oil test, but currently in a relocation process due to work.
