My mom's impreza will loose oil between oil changes with 0w-20 and will be fine with 5w-30. It burns the thinner oil.
My wife\u2019s 2012 Impreza is at 195k miles and I switched it to 0w-30 and then 5w-30 due to oil consumption. Was burning a quart every 1K miles on 0w-20, burns half that on 5w-30. I\u2019m actually considering going thicker.
The dealership here itself was using 5w-30 as the default for oil changes even though 0w-20 is stamped on the filler cap. After checking myself that Subaru said that would be OK, I started using it too for my own changes just to avoid flipping back and forth -- though I have no idea if that would be a problem. In any case, the Forester seems happy, even if the mileage may have dipped slightly.
Engine does become a bit quieter with 5w-30.
Doesn\u2019t hurt so why not. I feel like that\u2019s the main answer and what pushes me to do it.
I bought a new limited, last week. I did my first oil change yesterday and the amount of shit in it was crazy. Definitely do it.
I had a 2017 Forester with 175k miles on it and only used factor oil and never had any issues. I did not do any off road stuff and it was only a premium model, not a wilderness model. I don’t think it matters as long as you change it regularly.
Changed ours at 3k and will change again at 6k. After that it’s every 5k. Use Subaru oil and filters.
Do not listen to them. I have a 2015 forester non turbo I used 5w30 and had all kinds of problems id get codes for over advanced timing on one bank and under advanced on the other, I was getting power loss going uphill, weird chattering noise.
I have done all my oil changes myself since I bought my 2019 Subaru outback 2.5l new using 5w-30 and have never had issues! Just hit 120k ????
