Hi Everyone,
I have a 2013 Subaru Outback 2.5L that has developed oil burning issue. I purchased this vehicle at 105k miles about 2 years ago. My first low oil warning light came on at 3500miles. The manual suggests 7500 miles; however, this early generation of FB25 engines were notorious for oil burning issue. I had some data from car fax, and noticed the vehicle got oil change roughly around 3.5k miles. I had actually contacted the Subaru and they never followed up with me and I got busy, so I left it at that time.
After my first oil change 2 years ago, I noticed the oil burning has steadily increased. I put Castrol Edge 5w-20 and have changed oil back and forth Kirkland, Pennzoil to see if particular oil reduced the consumption. I have also changed PCV valve about two years ago. The old fun was still functioning (rattling).
Ever since my first oil change at ~108k, I have been trying to address the oil consumption issue one way, or another. I would like to note my vehicle currently burns 1 qt at roughly 1300-1400 miles.
Things I have tried:
Liqui Moly Engine Flush: No impact
Berryman B12: Gas tank. I bet the vehicle needed this as I felt increased power.
BG EPR: No Impact, or marginal as I did feel increased torque due to better compression? Done 3500 miles later than b-12.
Berry Man B12: in Engine: It didn’t do anything. Might have done some cleaning, but oil burn didn’t change.
Currently I am trying yamalube ring free. The instruction call for 1 oz every 10 gallons, but I poured 6 oz for my entire tank. It’s still running on it, so I can’t report anything. The last oil change I had was with Rosella t6, and it didn’t help with oil burn, my low oil light came on at 1400 miles.
I would like to know from the community, is there anything that’s proven to address this issue?
Browsing this forum, it seems HPL engine oil might be worth trying, or BG engine flush kit.
Thanks!!!
