12,000 mile oil change interval success

Sounds good, I'm sure BlackStone also tested residuals and metals.

FYI, you can request Blackstone to send you a rtf file. Then you can edit out the personal info. Use any free PDF converter (Google for one) to produce a PDF file and post here.

 

Nice report - I'm glad that M1 EP is good for at least that long. Currently I have Mobile 1 *regular* 5W30 in my Prius and at the 5000 mile interval I'm going to switch it out to Amsoil and try and get 15,000 or 20,000 mile intervals. I will test the M1 I have and the Amsoil at at every 5,000 initially to make sure all is well.

Good to see a syntetic oil doing what it was designed to do.

were you 100% city driving? how many cold starts? EBH? average tempearture? oil weight?

your leaving a lot of details here, i remember my m1 0w-20 had visible metal particles, but i had only around 12000 km i had to guess, nothing as crazy as you guys.

 

Great report, thanks. Going to 10,000 - 15,000 mile oil change intervals will help keep oil out of the waste stream. The first rule of conservation is that it is even better to not use something in the first place, even with a recycling program.

I am currently running ordinary Mobil 1 5W30 in my 2007 Prius. I'm planning on switching it out at 5,000 miles and going to Amsoil 0W20 for what I hope will be 15,000 mile intervals. I'll sample it at 5,000 and 10,000 miles to insure that everything looks good with running the oil that long.

Interesting....I have M1 0w20 synthetic with 8400 miles on the oil. I am amazed at how the oil appearance is still as clear as the day I put it in!! I haven't tested it but it still looks new!! My other vehicles' oil turns dark brown/black at @ 3k. Is this what most everyone else notices with their PRI ??? Is it the synthetic??? or is it just the Hybrid characteristics??? Going by the oil appearance , I definitely feel 15k is easily obtainable.....if not further...

 

Wow! Excellent report. Great viscosity, insolubles, flashpoint, fuel. Hard to believe that the oil was in there for 12k miles.

What kind of oil filter did you use?

 

at 10K I have the "maint req'd " light now on. I checked my oil and everything's great there. I'm almot positive it is the oil light as it started blinking at start up for a week before it stayed on.... just as it did at my first oil change. Does the computer use a mileage calculator to determine when to suggest the oil change or something more complicated. Also, why at 10k? Is that what Toyota recommends via the car as the oil change interval? Oil still looks perfectly clear. I'd hate to change it for nothing. I figured to be able to go at least 12-15k with how it looks. Any help or advise please??????????????????

 

The light comes on initially at 5K and after every 5K after the last time it was reset. I too am going for the 15K mark but may bump up to closer to 20K as my engine is probably off nearly as much or maybe even more than it is on.

 

the maintainence light just comes on as a suggestion you can reset it anytime, its just a reminder light.

so i just keep some of the oil and then send it to this company? or somewhere in canada i can drop off the oil, what do you guys usually catch the oil with?

How much does it cost? I'd really love to see if my 195,000 km car has some bad wear with 0w20 oil

 

Changing Prius oil at 5,000 miles doesn't make much sense, especially with Mobil1. Afterall, the Prius engine is not running nearly as frequently as a normal vehicle. Since all my other vehicles were fine with 7500+ miles using Mobil1, it seems likely that the Prius would be good for at least 50% more than them. Hmmm...since I had the 1000 mile initial change done, I think I'll go ahead and wait for 7,500 (total) for the first normal change, and 7,500 throughout the powertrain warranty period assuming the oil looks good. When that expires I might try 10,000 miles.

 

In Canada, I use Toromont Caterpillar SOS labs.

Toromont CAT : Oil Analysis Services S·O·S

However, the Toromont operating territory is Manitoba and Ontario. For BC, you would use Finning

Finning (Canada)

They have a sample pump for their sample bottles, and I highly recommend you invest the $20 in this pump. It is much easier to draw a sample through plastic tubing you can supply yourself, then to monkey with trying to catch a sample with oil draining out

Toromont charges me $20 to perform an analysis. It appears the cost can vary from $20-$30, depending on what region you are in

Hope this helps!
