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.
Ulje mannol 5w30 tdi. Isto ulje ja koristim za svoj audi. Tak da bitan je servisni interval pa mo\u017ee i srednje kvalitete ulje.
Mannol is a legit brand. Although not as critically acclaimed like Liquimoly, Rowe, Fuchs, Addinol, or Ravenol. Probably on par with Voltronic.
Motorban próbáltam, azzal olyan volt a váltó, mint amikor a Motul már cserés volt. Részemről inkább nem.
