2 Years of ownership and 60k later!

We have similar with both of ours -- one issue was fuel pump after 100k. We get amazing tire wear as well. The Gen 3's MPG starts to drop off after 65mph. I ave an employee who regularly got 60mpg with both of ours == he was an older driver and typically drove at 65 -- flat roads in good shape.

 

Add the EGR cleaning to your 100k tune up!

I'm at 94k and averaging 46 too. Great car !

 

Here’s a picture of a 100 k mile egr cooler for reference:


And here’s the after picture which involved 10 minutes and a pressure washer:



Good to go.

 

I get better mileage at 55mph than 65mph, there's also a table that will break down MPG average per MPH driven. Do a search for that table, never mind.

 

Should have said -- really drops off after 65. The OP talked about highway at 75MPH ... you are in the power st that point and it's really not much of a hybrid at that point ..... this starts around 65mph

 

I drive about 30K a year, my commute is far, about 120 miles round-trip. Most of it is highway miles driven at 70 MPH, except for passing through Hartford CT which drops the speed to 50. Despite having 17 inch Prius style wheels on, still getting around 50 MPG.

 

Now you need gunk and oven cleaner to get the stuff on the sides....

 

welcome to priuschat!

 

Meh, it’s just gonna get dirty again.

 

Very true! Still trying to find time to clean my original EGR Cooler. . I have a pressure washer, is this the better way to go?

 

Yes.

Try 10 minutes at 1700 psi and it’ll look like the pic above.

Good luck .

 

Thanks @Raytheeagle!

 

Depends on how clean you want it. Oven cleaner did a great job for me. Then I used gunk to finish it off.
And I used the my pressure washer to rinse the Gunk cleaner out.
Only took about 45 minutes to clean everything.

 

Consider cleaning the complete EGR circuit, and the intake manifold, and installing an oil catch can. Watch @NutzAboutBolts videos, pinned at top of 3rd gen maintenance sub-forum.

For the EGR cooler, what worked for me was Oxi-Clean solution, made with hot tap water and as close to saturated as you can make it: stopper one end, pour the solution in, let it bubble for about an hour, pour out, rinse out, repeat, about 5~6 times. Very effective, ended up like-new clean.

 

Since this has morphed into an EGR thread.....

How often mileage does the EGR need cleaning?

Is this on the Toyota maintenance schedule or something people here have figured out?

 

I did our 2010’s at 120 and 173 k miles.

After the initial round, then the follow up round, I’ll be doing this every 50k miles or so which for us is every 2 years. Our 2010 also burns a quart of oil every 5 k miles or so, which also plays into the equation for our 2010. Each situation will be different and have different circumstances .

Nothing in the maintenance schedule on this egr circuit cleaning.

But that’s how I’ll be proceeding .

 

Toyota has acknowledged there's a possibity it'll clog, but there's no mention of EGR in the maintenance schedule. I got this from Toyota Canada. It was really thanks but no thanks though: I was not going to sit around waiting for a code, and don't trust them to do a good job. There is really no need to replace any parts; you just need to take some time and patience, clean what you have.

In particular in the following, the statement "the majority of vehicles will not experience this condition" grates. I would say the opposite is true, that carbon build-up is normal and inevitable:

 

Sorry if this has been answered before. But in the US, do we have an extended warranty (and secondary warranty) on the EGR?
