I have a 2010 Forester and don't know much about cars. I get my car serviced at a Subaru dealership that's a decent distance away. I wanted to buy some locally, or online, but I don't know exactly which to buy. I looked at my latest service paperwork and the oil they used was listed as Mobil Clean 5000 - 5W30. I tried looking online, but it seems that Mobil Clean 5000 isn't around anymore and I think I read it's just been renamed as Mobil Super 5000? So maybe the dealership just hasn't updated their computer system with the newest name?
I called the dealership and the man I spoke with did not want to help me much, but just wanted me to come in and buy the Subaru branded oil from them, but I said I wasn't close by. All he told me was that I needed semi-synthetic, but wouldn't recommend a brand, marketing name, etc.
Would Mobil Super 5000 be fine to buy? Is that a semi synthetic oil I can use?
Thank you for the help!
You can use any brand of conventional, semi-synthetic, or synthetic oil that meets Subaru's requirements for your engine, as stated in your Owner's Manual. Like my 2010 Forester, your engine was designed to use the American Petroleum Institute (API) Service Category “M” (SM) grade motor oil stating the phrase, “Resource Conserving”, with an Society of Automotive Engineers (SAE) viscosity range of 5W-30, and a International Lubricant Specification Advisory Committee (ILSAC) classification of GF-4.
That same year, 2010, API "SM" oil became obsolescent and was replaced with the backward compatible "SN" classification and ILAC GF-4 was discontinued and replaced with GF-5.
So if you follow Subaru's primary requirement for motor oil you can currently use any brand of conventional, semi-synthetic, or synthetic oil that meets SAE 5W-30, API SN, ILAC GF-5 that states on the bottle the phrase, “Resource Conserving”.
There are actually three variations of API "SN" oil according to the API, with "API SN with Resource Conserving” but one variation.
