Worst Model Year: 2010; Worst Complaint: excessive oil use

Great, I have a 2010. But oil use seems 0 at 80k

 

Zero oil consumption @93,000 miles. Just for the record.
Too many variables to fixate on a cause. 43 complaints (reported on one web site) out of X number of 2010's on the road doesn't lend itself to an accurate statistical analysis. More anecdotal than anything else.

 

Add mine to the list of complaints. I still love my Prius, but it started using oil around the 95,000 mark. It has 150,000 now and uses just over 2 quarts per 10,000 miles. Need to do the IM/EGR cleaning and replace the PCV valve and hope that helps.

 

Call me old fashioned, but that sounds good for a car with over 100k miles. Modern cars generally consume less oil per mile than cars made 20+ years ago, but with longer oil change intervals it's more common to have to add between changes.

When I owned cars from the 80s, I'd have to add before the 3,000 mile oil change was due.

With cars from the 90s, I might have to add before the 5,000 mile oil change, particularly past 100k total miles.

My '00s lose a little oil between changes (longer than 5k miles), but they're still under 100k miles.

 

Excessive oil use? That's the worst complaint? That's like complaining that my tires with 20,000 miles don't grip as well when it rains. Oil use happens to all engines that get old. My PiP is starting to use some at 90k miles. It isn't enough where I would top up during my 10k OCI. The dipstick is lower than where I filled it is all.

Makes sense. If you only lose say a pint or so every 3000 miles or so, you may not notice. You will notice when you lose a quart by 10000 miles and that's a big deal.

 

In a similar vein, SOME year had to be the worst year Prius, that does not mean that it was a bad year.

 

Given those numbers, and those complaints, specifically and for Prius across the board?
I'm not worried at all.

 

Try our Insight, 2012 (and some newer) had TONS of oil consumption, ours was drinking almost 1"L"/1,000 miles at around 55K miles until the chamber got so gummed up with oil the engine died on us bending some of the rods. Luckily Honda took care of the $5,000 repair bill and hopefully the updated piston seals cure the oil consumption problem....

 

Just editorial: can't understand "IK", and the zero's got away from you? Did you mean "1 quart per 1000 miles"?

 

lol, yes, my mistake, 1l per 1000 miles (or 1k miles )

 

Meh....

Average repair cost: $428???
Yeah......right.

 

Can chime in on this. When the car was scraped it was burning 1quart / 450 miles or so. It was really bad. Mileage was mid-high 30s, no engine knock or codes, just drank oil. Started burning around 100K a bit and then progressively got worse, obviously.

 

108,000 miles and zero oil consumption.

5,000 mile oil change interval with Toyota 0W20 oil and filter.

Original owner.

 

Isn't ICE same on 2010 and 2011-2015? Why would 2010 be any better or worse?

 

It's the oldest year of the generation, now going on for 5+ years so they probably have the most miles. ICE is a bit different on 2012+, they replaced the intake manifold (problem with knocking sound on start that is ICE not wanting to start for few seconds) and probably a few other little things. 2010 also had the most recalls (brake pump, etc.), so it could be possible that they messed up something with the ICE too, or better said didn't realise the problem and fixed it on next years. It could also be that those problematic cars were from the first batch (produced end of 2009) which would fall under buy year 2010.

 

for comparison, it would be nice to know if people with oil consumption are original owners, and how they drove and maintained their cars. same for people with little to no consumption.
