#109 of 125 Stop using 5w- 20 weight oil
Dec 16, 2012 (7:17 am)
These engines are 1. either set up with piston, ring and cylinder wall clearances too great.
or 2. The valve guide seals are of a faulty design or material and letting oil leak by.
Use 15w-40 motor oil. I have an xB and have been using 15w-40 since it was new. I change every 3000-3500. The oil has never been low.
Just do it one(1) time, see if oil consumption slows or stops. Toyota doesn't own the car, it's
not their responsibility.
Make your life better!
#110 of 125 20 weight oil
Dec 16, 2012 (7:00 pm)
The problem is with the 20 weight oil. This is a trick the manufacturers have thought up to bump up their fleep mpg average to meet CAFE standards. Lighter weight oil gives the cars slightly better mpg due to less friction, but are they really good for the engine? I'd rather put 30 weight oil in my engine from now on.
#111 of 125 2008 scion xb
Dec 19, 2012 (3:22 pm)
I'm getting sick reading this forum. Is it only the 2008 that has the issues ? I just bought a 2008 Scion xb I had it two days and it seemed like the engine was vibrating only while in drive at a stoplight not in park or neutral let foot off brake it stopped. Found it to be carbon in the throttle they cleaned it out and works fine.
Do all the 2008 xb use alot of oil ? I've read a few posts where it said put in heavier oil has that helped? I'm afraid to wait til 5000 miles to change the oil. My problem is due to my disabilities, back etc the scion was the only vehicle i could get in and out of with ease. Funny thing is when i checked on scion on consumers etc nothing was mentioned about any major problems

I haven't heard about it either and I'm considering purchasing one with 95K miles. I also have a newer 2011 picked out as well. So, I would like to know, but in the first post where the guy didn't change his oil regularly, that will cause problems in ANY car and anyone should know better, just common sense. But I would like to know before I buy something I can't afford to replace and will be stuck in a 3 year car payment in.

This is my wifes car. I was driving it one day and heard a tick in the engine that I never heard before. I pulled over and checked the engine oil and it was bone dry. I would have expected the warning light (oil light) to be illuminated when the oil pressure drops below a certain point but it never did. I called in and they had me do the oil consumption test, but unfortunately I don't have the time to take 2-4 hours out of my day to do this and often forgot so it was pretty much useless.
I will never buy another scion, perhaps any toyota product again.
I would understand if the vehicle was from the 70's or 80's that it might burn some oil, but never for a brand new car and never at the rate at which it burns oil. I also don't understand why the oil lamp never came on or no other indicators letting me know something was wrong.
I've come to the realization that I'll need to check the oil every couple weeks and will probably change the oil weight and maybe even install a oil pressure guage.
Then unload this pos as soon as I can.

So far my 08 xb has had no problems when I bought it a mechanic told me to use 10-30 motor oil haveint had any oil loss I change oil every 5000 miles. I have 55000 miles no trans problems nock on wood. ">
#115 of 125 04 xA 128K and 06 xB 144K : both nearly perfect
Jan 25, 2013 (3:29 pm)
Some things are luck of the draw and some are brought on by the caregiver.
Our 04 xA: only maintenance other than oil, wipers and brakes were new shocks at 126K in its entire life. To me this was "elective surgery" as we could have ignored it for a lot longer.
Our 06 xB: at 142,000 miles we replaced the heater/cooler fan motor for under $300.
That is it, both cars, total 270K miles and a single nonelective repair.
Compare to our 2000 Mercedes Benz ML320, which failed in every conceivable way through its 140,000 mile lifetime... this includes a the windshield washer reservoir (cracked at bottom seam), power door lock actuators machine gunning (all 4), "Christmas Tree" dash lights blinking madly,
AC compressor, power winder switch panel, CD deck, then the entire radio, transmission, motor mounts... and many others. If you really want true headaches then buy Mercedes Benz!
Do care for the cars: synthetic oil every 7500 and you're usually golden at 30+ MPG.

I'm loving my 08 xb now I can't believe the problem I had was so simple and toyota couldn't figure it out. I had the vibration like some others were talking about only in drive while idling went to dealer 2x more or less said nothing wrong so have to live with it. But it was so loud sometimes i taped it but before i went back I decided to go to my own mechanic who fixed my old van for years and guess what it was the stupid hood vibrating they turned the rubber pieces and in a minute had it fixed. I sitll haven't been back there yet but i'm goign to call service one day and let them know LOL

Similar problem here. 2005 scion xb sputtering upon acceleration and not effected at high speeds if it will get to speed at all. Seems to be running rich however comes and goes and will not start now. mine has been in the shop for 2 months and they can't fix it. Did you ever find out what was wrong with yours?
