I have an '09 pontiac vibe AWD with the 2AZ-FE engine and it burns a significant amount of oil. With 162k+ miles. I've been adding some over time but I want to mitigate how much it's burning.
It also gets really bad gas mileage, when my low fuel indicator light came on I was at 203 miles on the trip meter. For an 11 gallon tank that is pitiful gas mileage.
What can I do to somewhat remedy this?
I have the same motor. Not a whole lot you can do aside from rebuilding it.
I've had decent luck switching to synthetic oil and using additives like:
Bar's Leaks Oil Seal Engine Oil Burning 16.9 oz - Walmart.com - Walmart.com
You can put one of these or similar additives in every oil change or every other one. Lucas oil stabilizer can also help slow it down significantly.
To resolve the oil burn issue, you should rebuild the engine which is not worth it, So add oil as it needs.
About the gas mileage, change the air filter, clean the MAF sensor, and change spark plugs. Remember to have correct pressure for your tires.
@yaser
I have already changed the air filter and spark plugs, I already have the spray cleaner for both the MAF sensor and the throttle body, which I plan to use soon.
I have a scan tool that can read some live data and I have not yet seen the short and long term fuel trim...
About $2500 + tax and labor could get you a reman engine with a warranty.
The cast iron cylinder wall sleeves are thin and not supposed to be honed to create crosshatch. That is what the piston rings seal to for compression and prevent oil consumption.
There was a "recall" of sorts for 5 years or 60,000 miles that involved redesigned pistons and rings.
@heyinway
I know it's not a recall otherwise I'd just go to Toyota to get the work done. TSB's don't work the same way I don't think. I could try going with my old carboned up spark plugs as proof that it burns oil, but I think it's way too high mileage for them to do it free, even if I mention Scotty's name, like his customers do.
