Used oil analysis 11/1/2016

Used oil analysis'.


I'm still waiting on my new engine to arrive at my local Subaru dealership for installation. I wish I could be driving it right now and racking up more proudly-driven miles like you and many other members have.

Sorry for the delay but I was waiting on the latest. Just got the latest oil analysis back from Blackstone labs and the results are, drum roll please. EXCELLENT! After 201,000 miles she has almost the same results as the first analysis. I did change the oil a little earlier this time just as a matter of convenience but as you can see, it made no difference. If you are curious, I am still using Mobile1, OW/20 extended service oil and the Fram synthetic filter.
Still have the very intermittent TPS sensor but other than that, no issues.
Just put on new shoes. Gonna try Goodyear Assurance UltraTour this time because I couldn't find Pirelli P4 or P7 anywhere in stock. At 4k miles a week, I don't have the luxury of waiting for an order.

For the miles you've been piling on, you've got quite a bit less iron per miles than my old 2014's engine.

The worst I've gotten was 15 ppm of iron in a 8,110 mile oil change interval (excluding break-in oil change), which I know for a fact I really beat on the engine. I've almost religiously run the Subaru/Idemitsu 0W-20 w/ API SN and still impressed my results aren't too bad for beating on my engine heavily.

However, the oil consumption, although within spec for all oil changes except the recent one, would be something a typical vehicle user would deem unacceptable.


Here's my numbers crunching on the iron correlation to OCI mileage

So with mileage to iron content found in the samples, the recent city driving type commute has significantly more iron wear per mileage. The freeway commutes are clearly easier on the engine.

Not suprised at your numbers. City driving is definitely harder on an engine. I've noticed that during a windy time of year, I use more oil. Granted it's not a significant amount but it shows that the harder you push these engines, the higher your oil consumption, thus more wear.
For comparison, I inspected my brakes this weekend and they still look new. You won't get that in city driving.

A couple more inches

Well, mama said I could use a couple more inches (?) so, I bought a lift kit and finally installed it. This is;
http://andersondesign-fab.com/xv-crosstrek.html
Excellent quality kit. It raised the car 2" without any noticeable change in handling and I only seem to have lost about 3/10th mpg. Definitely clears badgers better!

The lift looks great. I could have used that about 2weeks ago. On my drive from Rhode Island to Kansas I crested a hill at about 75mph and right at the top was a deer carcass.. Nothing I could do but go over it. I heard it graze the bottom of the car and thought for sure I'd ripped something off. Pulled over and inspected and didn't have anything at all. I'd love to have a few more inches of ground clearance.
I'm now up to 12k miles on my Crosstrek, probably will put another 4k in the next 2weeks.

Great thread, look forward to seeing and hearing more.

Thanks Zero,
I just put it on last weekend so after 4,000 miles, I'm very happy with the outcome. Ready for the snow now.

 

[AWDfreak]

That lift looks so awesome!

I don't have the guts to try such a lift (I actually enjoy the stock ride height), but I look forward to some off-road shots and videos with the lift.

Thanks. This is an excellent kit because it is the only proper way to lift. There is no strain or distortion of components like the rubber spacers that many people use. This way you retain the handling and ride. The suggestion that anyone can install this in 3-4 hours is probably a little off. I am my own mechanic and have replaced many engines, transmissions and countless brake jobs. took my time and I have all the tools necessary, including a transmission jack that made it much easier to lower the rear end and it still took me 5-1/2 hours to finish.
If you are planning on a lift, I highly recommend this kit because of the quality of the steel used, quality of the welding and the cost. Just be aware that this should be professionally installed and although there has been an offset included to allow for alignment differences, you should still count on having an alignment done immediately afterwards.

1/4th of the way there!

15 months and 1/4th of the way there. She may not be the prettiest thing in this picture but the she's still running great. No new issues.

This makes me all sorts of happy. I'm pretty sure you're the only one on the forums that drives more than me, so it's really nice knowing about potential issues (or lack thereof) and things to look out for. So I sincerely thank you for taking the time to document everything.

Wow.. Seems like most everything has held up well with the amount of miles.

Whats your MPGs been like being majority freeway driving?

I will as they come. I know I always like to know about potential issues ahead of time.

Well, I keep the crossbars on the rack, I have a 2" Anderson Fabrication lift kit, I switched tires to a more aggressive Champiro Ice Pro tire and I average 70mph highway driving which includes about 10% city, 5% mountain and 85% highway driving. That being said I'm averaging 28.8mpg (actual). With all season tires I average 29.4 (actual). Not complaining at all with those figures.

Nope that all makes sense.

I plan on picking up a Crosstrek this summer. I have a 30 mile each way commute (90 % freeway). Plan on having bars and the 2 inch lift. So seeing/hearing real world numbers is always nice.

My STi, on the stock motor and driving as easy as I could, would get 24 MPG - spending $100 a week on gas. So I bought an older civic just as a DD. 35-40 mpg depending on how I drove and $25 a week in gas. I think ill be selling the civc to get the Xtrek.

Definitely a different car but lots of fun and it'll go anywhere.

I plan on it being the complete opposite of my other Subaru - tall and slow lol

Well it'll definitely deliver on that. Haha.

Alternator

260,000 miles and my alternator gave up the ghost. Pretty good considering my 16 hour commute consists of 8 hours of night driving so DRL's on 8 hours and high/low beams on 8 hours 5 days a week. That puppy's working hard!
Not cheap but the easiest change over ever. Hood up to hood down, 10 minutes.

 

[AWDfreak]

How did you find out the alternator was going bad?

I notice sometimes the voltmeter on my Ultragauge goes down to the 12's but so far I'm presuming that's a feature of the so-called "fuel saving" charging system.
