Engine oil Motorex or OEM Subaru

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.

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 ????

Getting 30mpgs in my ‘14 and been running 5w30 for years, smoother and quieter

No issues with 5w-30. Switched my 21 Crosstrek to it due to the summer months coming. Little dip in mpg but the engine runs smoother.

Either way I have the impression that the engine has a smoother sound and feel now, can this be possibile or it's just a placebo ?

They sell Subaru branded Idemitsu at the parts counter

It takes a “synthetic blend” of motorex 15W50 oil. And uhh yeah works good I guess, don’t have to change it too often, and as far as performance goes, it doesn’t really matter because I’m on restricted power anyways so yeah ????‍♂️

Honestly Motorex is a good oil, but it is extremely expensive for what you get. I specialize in performing Used Oil Analysis (Worked for Reliability departments for mining outfits) and it’s just a Ho Hum oil.

I avoid the 5 minute drive-thru places. One of them wanted over $100 for full synthetic on my Subaru Forester. Not worth the 5 minutes.
