2010 Prius Owners - High Mileage and No Oil Issues

Please list your mileage? 135,000
Please list if you change your oil at 5,000 miles or 10,000 miles? I used to service every 10k (up until I reached 90k), but since then it has been every 5k.
Please list if you use 0W-20 weight oil or something else? 0W-20
Please list if you have the dealer change your oil or someone else? DIY
Do you use Toyota Oil? No, usually use Mobil 1 Extended Performance.
Do you drive mostly city or freeway? 2/3 Freeway.
If freeway what is your average speed? 75mph.

 

My car is a 2012 Plug-in.

Please list you mileage? 97,000
Please list if you change your oil at 5,000 miles or 10,000 miles? 10,000
Please list if you use 0W-20 weight oil or something else? 0W20 Mobil 1
Please list if you have the dealer change your oil or someone else? Now that free maintenance is over, I do them.
Do you use Toyota Oil? Mobil 1
Do you drive mostly city or freeway? Suburb/Freeway
If freeway what is your average speed? 70 mph. I am not a hypermiler.

I might change to 5K intervals. I read an article that motor oils have fewer detergents and 10K intervals aren't ideal. I also might change to the next thicker oil grade, to prevent leaks.

echo that ...162000 no oil burning

 

I seriously doubt. But a person who runs an oil change business can boost profit a lot by charging for synthetic and using non-synthetic. Or, use the lowest quality, cheapest synthetic there is.

 

I purchase 5 qt size. mobile1 DIY is the way to go... Or find someone to do it for you besides the Dealership... I try to turn wrenches where I can. My next venture is to remove dash to "wipe" off the "anomally"... Over the right side of the Dash monitor...its cloudy blurred and just a eye soar...anyone done it yet? Where the consumption meters get fogged up beyond recognition!!!
I Just did the throttle butterfly, it was really sooty. included picture. easy to accomplish too. Id really like to get to EGR cleaning ASAP. I Also changed spark plugs. Runs smoother, with higher MPG's!

 

I'm doing DIY, with bulk Toyota 0W20. Well, for one change so far, it was bottled Toyota oil before that. I'd agree DIY'rs tend to be more on it, changing the oil "on time", or more frequently, and checking level frequently, which at least avoids oil starvation.

The mechanics of buying bulk oil, at least at my dealership: it's defined as a "service". I show up at the service counter with my bottles (pair of 4 liter repurposed canola oil containers), which they fill and bill me as a service, parts only ($4.50 per liter), no service charge

The appearance of the bulk Toyota oil was identical to my eye. It's a "known fact" that bulk oil is no good to Ed the Fox, that's about it. It was just getting to me: all the oil contaminated bottles I was putting out.

 

How do you think they fill the bottles versus the bulk drum? It all comes from the same large vessel at the facility it is manufactured. Otherwise think of the scale costs and what cost per bottle would be otherwise.

 

I actually use a dealership near me. Only on Sunday's though ( they take $10 off the fee). I take my own oil and they supply the labor and filter. Their waiting room is across from the oil change bay, so I get to view the work from the comfort of a lounge chair and a warm caffeinated beverage .

So for $45( this includes the cost of Mobil one off of amazon) I get an oil change that I watch and don't have to crawl under the car to do.

Also checking out the new 2016's helps pass the time. I started to take a shine to the Prius Eco, then realized it was time to grab a coffee and watch the oil change

 

I was listening to the CBC radio one time, they were interviewing a recycler, who deals with used oil bottles and oil filters. One plea from him: take the time to really empty the bottles, as well as you can, reduce the oil left in them. But yeah, just like bulk food, if you can buy bulk and bring your own containers, everybody wins.

 

I can honestly say I have never seen the difference between the 2 with regards to engine oil and the process they perform to manufacture.

I have worked in the chemical manufacturing world for 12 years and when we manufactured materials in vessels, we would have various packagings we would fill from the same batch. This would be drums, totes and bulk tank wagons or rail cars all from the same material. Why? It was easier and led to less conversion of the equipment between grade changes.

If changing grades, we had a "cleaning matrix" that would be referenced by the operator to determine what (if any) cleaning would be required for both the mix vessel and packaging.

I view engine oil in the same light and it is probably treated that way. My parents also had a neighbor who worked for a large beverage manufacturer. They do a similar thing for bottling sodas, teas, etc.

While handling liquids and cross contamination can happen (and does from time to time), it is not more rampant than the rouge noob mechanic entrusted with your car and putting the correct oil into your car ( if at all). I use the trust but verify approach at the dealer and found one that I can easily do this.

Other dealership oil change negative factors that might be at play:

1. Chronic overfill.
2. Unchanged (or omitted!) oil filter. These are easy to do, and very hard to detect on third generation.
