Struggle to commit to a 10,000Km oil change interval
- Thread starter TRX200SX

10k km on good XW30 is fine IMO, and that's what I do now. The discount 0W20 the dealer used in our Outback wasn't ideal, and it was varnishing up at those intervals in 60-70k km... 0W16 seems
We accidently did a 16k km OCI this spring and even over that interval, it had burned just under a litre.

I believe that 7500 mile recommended OCIs became the norm around 25 years ago. Why worry about 6200 miles unless your driving qualifes as severe duty? That doesn't appear to be the case from what you've told us.
Be careful following blanket statements, they're a great way to get into trouble. If you plan on extending an OCI or venturing out of your comfort zone get a UOA and use the data to help determine your OCI. What's good for someone sharing info from their vehicle might not be good for you.
10k km is easy and a no brainer for modern oil.

Why are you struggling? Clearly, you're not comfortable with 10k, so why are you trying to do mental gymnastics to rationalize it? With a FUMOTO valve and a top side filter this is the easiest car on the planet to change the oil, most of the that time waiting for it drain, and is $40 for oil and a filter going to break you financially?
Make the decision you clearly want to make to keep it at 5k and move on with life.
You have a good plan. Go for it!
10K km is 6K miles. Here we run that many miles with oils that have lower viscosities and inferior approvals than ESP 0W-30. The oil is rated on paper for 12K miles / 19K km. That oil is definitely good for 10K-12K km for sure. You are good.

Are oil change intervals based on how long an oil can be kept in the sump, or what's the best mileage for engine preservation? I doubt manufacturers recommendations are to ensure your vehicle lasts as long as possible.
I'm not familiar with Subaru oil life monitors, but most manufacturers use an algorithm which takes operating conditions (cold starts, idle time, city vs highway driving cycles, etc.) into account. If yours shows 15% - 25% oil life remaining when you reach 10,000 kms, then that can give you confidence that your maintenance schedule is more than adequate. Especially with a premium oil like the Mobil 1 ESP you're planning to use.

I’m running a 2012 Jeep Liberty with a 3.7L Powertec V6. When I first bought it I just changed the oil when the computer told me to, usually 8K miles at the most convenient quickie lube joint. But as cars got more technology advanced and I became more inclined to keep my older vehicles as long as possible; I started doing my own oil changes with top tier motor oils at 5K miles strictly. On my last OCI I tried to push it an additional 1K. It caused way to much anxiety. Probably unjustified, but I wasn’t sure about the Purolator filter I had installed. All in all 10K seems reasonable.

If it makes you feel better to change the oil sooner (ie at 5000 or 6000km) , do it. It's your car, your time, and your money. You do as you please.
IMO you'll be perfectly fine with 10,000km oil change internals using a good quality oil (like the oil you've stated in your first post).

I read it as 10k miles too lol yeah OP is good on a 6k mile interval for sure. Just keep an eye on the oil level every so often on the dipstick and use a quality filter.
I did 7k or 8k mile changes (7.5k was the manufacturer recommendation) with my 4 cylinder Suby Outback over 100k miles, never a problem. Some heavy use, fully loaded down inside and on top with full size roof rack basket up and down the East Coast interstate on round trips of 2,600 miles a half dozen times.
Traded car in at 100k miles, it still performed well with no engine issues. YMMV
As specified in the manual, with a 2.5 L Forester I go 6000 miles between oil/filter changes. As not specified in the manual, I use Mobil 1 ESP 0w30. At 37,000 miles now. No oil lost between changes as per the dipstick, although I don't know about the possibility of fuel dilution. MPG's in low 30's. I feel no hand-wringing need to change it earlier with this thicker-than-standard good quality oil.
The factory interval is already extremely conservative.
This guy just did a UOA on a 37,500 km interval.

Everyone wanted me to use a different lab that showed oxidation, so this time I used SpeedDiagnostix.
Not trying to put you down, but it was barely broken in, lol. 100k miles is really nothing with today's oil and engines.
Can't agree in all cases.
Turbo/DI vs NA/Port Injected is one case.
Short trip vs highway is another.
Some engine designs are better suited to shorter intervals.
Only a UOA can say for certain if your interval is safe (in the case of a longer interval) or a waste (in the case of a too-short interval) for your engine, your oil, and your driving habits.
That said, 5000 miles/8000km is a good starting point.
Unfortunately, many here may not have noticed, or were not quite able to decipher, that you were asking about a 10k km oci, aka a 6200 mile oci. Unfortunately, our friends up North may have to explain things in simpler terms that will not confuse those on this side of the border, that are SI (metric measurement system) challenged.
