did the tuning shop also recommend the 5000 mile oci?I noticed that there hasn’t been much talk about Motul. My tuning shop swears by it and I’ve been using 8100 X-Clean EFE 5W30 for my last 3 oil changes. Seems to work just fine, operating temperatures for daily driving look about the same. I change every 5000 miles almost on the dot.
I used to use Mobil 1 full synthetic, but after seeing a number of reviews about how it doesn’t play well with TGDI engines I decided to switch. I’ve also stopped using their filters and switched to OEM Subaru filter.
Some people have talked about how Motul isn’t an engine oil that prevents pre-ignition, but when you ask why they normally give an asshole response and don’t really explain anything. If anyone has more info on this I would interested to learn.
