Anyone get their oil analyzed?

[cliffish]

I just sent my first one to Amsoil-Oil analyzer. It was from my 2016 Subaru Outback with 158,000 on it. I have a problem when I push my oil change interval to 6,000 miles or so. The oil light will come on and it is down about 3 quarts. It has happened a few times in the last few years. I think fuel is getting into the oil and combusts? Today I changed it at 5,000 miles and it was right where it should be on the dipstick. I don't see or smell any indications of it burning oil.

Anyone have possible thoughts on this? or sent their oil out for analysis? what did it reveal?

thx

Losing 3 quarts is extremely significant. How many does the engine hold? 5 or 6 is typical. I thought fuel leakage made the dipstick level higher, not lower.

Hard to believe you can lose 3 quarts in 1,000 miles. You sure you had it all in there to start with?

Antone??

I know, that is what has me perplexed. I do all my own oil changes, add 5 quarts every time and check after I complete the oil change. Bought the car in 2018 with 52K on the clock, so don't know previous records. This has happened on at least 3 occasions since I have owned. I have never had to add oil with 5000 or less miles since the last oil change.

Is this a turbocharged engine? If so, could be the turbo seals are worn.

Nope the normal 2.5 4 cyl. Have 3 of these engines in the family and this is the only one doing this. Other than that it runs great and gets great mileage.

Clearly you've never owned a Subaru, or if you did probably not one near or over 100k miles.

Yeah, not my style.

I had a car (Fiat) that lost 1 quart in 100 miles, but the bolts that held on the valve cover were missing.

The only car brand worse than Subaru!

At a 158,000 the only thing I have replaced other than brakes and tires is both front ball joints. A boring car that just does what it is supposed to do.

Did you already forget about all that oil you had to replace?

only went short 3-4 times, so not massive. I try to keep it to no more than 5000 miles
