For the longest time my 2002 Toyota Sienna, now with 225k on it, was holding steady at an oil consumption of ~13 .oz per thousand miles. Since this last oil change, about 2,000 miles ago, that has jumped up another 3 oz.
It's smog test time again and I'm having the devil's own time having my catalytic converter monitor set. It's always been a little difficult but never this bad I've driven the two types of Toyota recommended drive cycles three times each and still nothing. Whereas usually doing just the one a couple of times takes care of it.
So I'm wondering if the additional oil im burning could have anything to do with my Cat monitor not setting?
If so, do you think adding a oil thickener, so hopefully less is getting past those piston rings, will help
