2019 Prius Prime, 341K miles, looks like far fewer

If you listen carefully to the commentary you get that the 349k miles was done in 3 years. No wonder ther is no rust. Rust is a time sensitive item. The older the car the more rust.

 

must be a lot of highway miles too. still, you can't complain about 340k with no major work. might be a good sign for egr's head gaskets, brake actuators and etc.

 

Huh, the Prime has a different hybrid fan intake than regular Prius?

 

Makes sense, much bigger battery. More to keep cool

 

341K miles in 3 years would be ~114K/yr. If he drove 5 days a week, it would be 437miles/day. So, that is 412miles/day of HV drive, assuming he bothered to charge the car every day. He has to be one of those 10% gasoline superusers.

It would take me ~42 years to drive that distance on my PP... No, I don't think the car will last that long... or maybe, But I will be dead before the car. LOL

 

Yes, two large intakes to supply the two fans in the back.

 

If your on Reddit, the owner of this car is a Redditor u/hwy_boy. He regularly posts updates on his Prime.

 

Interesting article. We're at the opposite end of the spectrum, using the car once or twice a week, for family related stuff as often as not. Or an appointment. Occasional outing.

But yeah, we have family members who drive to the States to shop at Trader Joes, bring along gas cans, the whole rigamarole.

 

Here is a dedicated thread on that topic. Are you a gas 'superuser'? U.S. state wants to get you to stop | PriusChat

At least this superuser in the OP's video is driving an extremely efficient "gas" car, not like a pickup truck. I wonder, if every superuser drives a gas car as efficiently as Prius (just a hybrid type), what would be the impact on the total gas consumption? I have a feeling that would be a bigger reduction in gas consumption than waiting for a cheaper and longer-range BEV and wider charging infrastructure to come to the market.

 

Maybe. But just curtailing the driving is the dead-simple method, should be considered as well. Multiple approaches. I recall during the initial COVID lockdowns, before complacency returned, and pretty much everyone became an "essential worker", there was reports the air was noticeably clearer.

 

Agreed. If everyone stayed the way they drove during the early 2020 level, we have reduced the CO2 level by now. On a different thread, there was a graph of automobile-driven miles. It is now right back to the pre-pandemic period.

Of course, I don't know what the economy would be like if transportation was restricted and reduced at the level of the early phase of the pandemic.

Personally, we managed to reduce our annual driving miles to roughly half of the pre-pandemic period. I posted this graph from the analysis I run on our driving data for our household of two cars except for one year during 2018 when we managed with a single Prius Prime. Nop, we don't plan to go back to the pre-pandemic style of driving even if the gas price plunges. Note that our predicted gasoline usage for this year (estimated from the first half of this year's usage) is almost 1/5 of the pre-pandemic peak usage.

 

I leave things in my car so that I can handle those matters well on the road handling some other matter and combine trips

 

The owner of this 341k PP recently sent his oil out for analysis. Here's the result.

 

Not too surprising results, if the regular oil change maintenance has been performed (in his case, every 10Kmiles not once a year). I would be interested to find out if he has done transaxle fluid changes, if so how often, and what the oil analysis result would look like.

 

ha, it's these posts that makes me think I'm a sucker for getting a new one...340k+ that's damn impressive...

 

Quite nice....
I've got a question though: I understand that he can move up to a 12k OCI...however @12k intervals, is he seeing any oil consumption or oil loss? Many modern JPN engines I've seen have some Oil Consumption/Burning, which would make 12k intervals in my opinion kinda tough to achieve without topping up at some point...

 

Always found “top up & change” routine is viable on older cars.
Yes all older engines , not just JPN build would have squeaks leaks and hot flushes.

 

Is there collaborative data from people who regularly change their prius's oil at intervals greater than 10,000 mi so that we can determine what the long-term effects might be?
