We've repeatedly noticed about 10-15% lower MPG for the 1000 miles right after an oil change. No change in oil brand or viscosity. Any idea why?
California has passed some new laws in recent years regarding allowing certain low-emissions vehicles in the HOV lanes with a single driver. For...
I would try to find out if it is consuming oil. Many Toyota Prius cars of that age have this issue. Hopefully there will be a class action...
Thanks! Does this work when the leather has already gotten rough / cracking?
The top section of the steering wheel on our 2010 Prius is getting all dried out and rough. It's probably mostly from sun exposure, and maybe a...
Our thoughts are very similar to yours. We are going to work with Toyota to try to get something accurate in the documentation before the Prius...
Thanks, Mendel for the document and for your ideas! We appreciate it very much! :)
A balance is needed. Parts require energy to build, use precious metals such as platinum (catalytic converter), and hit the pocketbook real hard....
The print is small, but it sure looks like -7 degrees Celsius is what they are claiming for the lower limit for 20W-50. See: Excessive oil...
@Mendel Leisk Maybe we should really warm up the engine by taking a drive to Northern Northern California. Or as you call it, Vancouver....
Yes, parts almost certainly has quarts. Don't know about service. Not sure which they actually used, as service is likely more familiar with...
Ya, if we're reading that chart correctly, the cutoff for 20W-50 is -7 degrees Celsius, which is not too far below zero.
It was about an hour drive, mostly going 70-75mph. Not sure how the oil was dispensed. They didn't do it in front of us. Just speculating that...
Thanks so much Mendel, and for posting the photos. (y)(y)(y) Not sure whether or not 8km is sufficient to really heat up the oil all the way. We...
Assuming they were joking (hopefully).
Thank you for that reference! Is that from Australia (or Austria?)? Is it the same exact engine and other components that could be affected by...
That's what we've heard. Do you have reliable references for standard oils used by Toyota in other countries that use an identical engine and...
Thanks. Why did you switch to 0W-40 if no oil consumption?
Did you have oil consumption issues using 0W-20 or 5W-20? What about with 0W-30?
I wonder when Toyota says to fill with 4.4qt of oil, if they take into account that it will expand when it is hot.
