Well, trying to figure out if I should change my oil now or not.

Short version:
Scion in sig, 3000 miles in 8 months on Auto Zone 0w-20 synthetic/CQ Blue filter. Lots of short trips, but several 50 mile highway trips a month.


Long version:

Yes, I know UOA is the only way to tell for sure, but not going to happen.

This is the 2012 Scion xB in the sig, right at 38,000 miles on the vehicle.
First 5 oil changes were done at the dealer using TGMO 5w-20 and Toyota filters (free).
  • 4,930 miles, 6 months
  • 4,798 miles, 6 months
  • 3,763 miles, 5 months
  • 3,107 miles, 3 months
  • 3,261 miles, 4 months
Now, a 6 month/5,000 mile interval using synthetics (hoping to prevent the clogged piston oil holes/consumption issue the 2AZ-FE has).
The past 3 changes were with Pennzoil Platinum (pre GTL technology oil) 5w-20.
  • 4,988 miles, 6 months
  • 5,152 miles, 5 months
  • 4,976 miles, 6 months
Current fill is Auto Zone 0w-20 Synthetic.
Last oil change was December 2, so I am over 8 months since last change, but only ~3,000 miles into this OCI.
My wife quit working last October and now it is not driven near as much.

I feel like if I change it now with so few miles, I am wasting oil, but at 8 months, it means lots of short trips.
It does make several 50 mile highway trips a month, so not really worried a lot about fuel/moisture dilution.

So should I just go ahead and change it now, or just wait for a full year/5000 miles?

I would think you're fine but this

"Now, a 6 month/5,000 mile interval using synthetics (hoping to prevent the clogged piston oil holes/consumption issue the 2AZ-FE has)."

Says you may just want to go ahead and change it this motor is known to have issues like that.

Just change it at 6000 miles, even if it takes you two years. Even that is conservative - just keep it topped off.

I'll get yelled at for this one, for sure: How does the oil look on an ink blot test on a white paper towel?

Full year / 5,000 miles due to the 50 mile "purge" trips.

Ok, I'll bite. Why? The only diesel I worked on was a 2007 Isuzu NQR with the 5.2L 4HK1-TC engine. Very few miles, less than 30,000.
Whenever I changed the oil in that truck, it would turn BLACK as soon as I restarted it. That quickly. Thus making the blotter test pointless (if going just by color)

That is the main reason I am debating changing it now. Supposedly it was fixed by the 2012 model year, but only way to know is time/miles.
The 2AZ-FE was used in few vehicles for the 2012 MY (I think the xB was the only vehicle using it still), so not a lot of 2012 data out there.

Don't think I could ever make myself go 2 years. Me waiting for 1 years is a huge jump.
So far, there is no consumption.

This is on a coffee filter, the red circled one is a drop of new oil (same brand).

Her highway trips are well over 1/2 the mileage on it, so as I said, fuel dilution/moisture contamination is not a concern.

With so much oil sitting in my stash, I am just getting the itch to change it.
Maybe I will go change my mother in laws oil.

IMO....your under utilizing a good mid-range synthetic. As long as you take those 50 highway miles a few time a month, your short tripping should be negligible.....so 1 year or 6 to 7K should be OK. I would also suggest an 0w20.

I would also suggest getting a good top-tier filter such as the Fram ULTRA.....which can be used for two OC's (up to 15K). Its reasonably priced and can be purchased on-line or in the store, at you local WalMart.

Don't know how much fuel dilution one gets with cold starts in TX. I just dropped the oil in my 2013 Scion after the OCI light went solid and felt guilty as the oil looked very clean.
Not all diesels turn the oil to ink instantly. My third 7.3 now after several thousand miles on the oil change still is a caramel color(74k). Seems the 7.3 can go to 120k+ before its starts carbonizing up the oil.

Run it to the full year. And if you're worried about synthetic oil changed every 3,500-4,000 mi. letting the pistons get stoved up, keep the 5K change interval and run 89 octane in it.
