Cost of Cleaning EGR system

Glad it's back to normal.
It's always best to stick with a known brand of fuel. Stay away from the cheap 7-11 type places.
They get any brand as long as it's the cheapest.

You'll have to look at the sticker on the door, but I believe it's 36 front and 32 rear.
The few extra pounds should effect the life of the tires much, if any. Now if you went 10 pounds over...

And an update. The problem was much more simple, so much I have difficulty believing:

Gas quality. Perhaps also the slight increase in PSI.

I used to fill up with Kroger Fuel--they share points with Shell and I thought the quality could not be that different.

The difference is shocking. I now just use Shell. Though the temp is higher now, I went from 36 MPG to 49.8 MPG (which includes a lengthy period of idling with the heating on). This over about 1200 miles. I am not making this up.

I don't think the temp explains more than a few MPG, as I rarely got more than 42 even in the summer. My year-long average over about 10,000 is 39.8, including the latest awesome numbers.

I am floored. My only complaint about the car was due to such a simple thing/mistake.

I am going to return the tire pressure to the recommended 35 (I had it at 38 for the front and 36 for the back, following recommendations on this page). If the good numbers continue, I will keep it that way, as the higher pressure decreases tire life of course.

It's like getting my old car back. Have not seen those numbers since, well, I made the stupid decision to use the silly discount of 5c from Kroger.

Please, no lectures, as in "You should have read the posts." True, but not many talk about it in such terms (though enough for me to try switching gas). Most go on about many technical fixes, hence the above post.

In case you have another non-expert asking about MPG, do make sure to ask them if they are using Shell or not.

I even tried a tank with no ethanol gas--Shell is actually doing better, though here it may be the temps that are making the difference. Anyway, non ethanol does not make sense cost wise, it is 30% more expensive.

I think over the summer I will be hitting over 50. I'm in love with my Prius again!
