Jolbaru_LGT Posted January 6, 2023 Share Posted January 6, 2023 So, I typically use Motul XCess 8100 Gen2 5w40. I’m a little ways away from doing an oil change. What oil can I add for just topping off, that’s compatible and readily available at the local big box auto parts store? Someone recommended to me at the autozone Mobil European formula 5w40. So I put that in, now I need to get another quart just to be on the safe side. Should I track down another quart of that? Or doesn’t it matter at this point? Did I screw it up and should I do an oil change with the Motul? sorry, maybe I’m overthinking it. Thanks Link to comment Share on other sites More sharing options...
Max Capacity Posted January 6, 2023 Share Posted January 6, 2023 Yeah, I would just get another qt of the Mobil. Oil is oil, What are you doing for normal oil change intervals ? I just buy Amsoil 5w-40 by the case and their EA15k13 filters 6 at a time. Do the 7-8000 mile oil changes. Blackstone Labs will tell you how good that oil after 7000 miles. If you have the Motul on hand... 1 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

I get a bit worried after 3K because I don’t delete those banjo filters, I replace them. I’m not sure if that worry is justified or not? I’m also not opposed to waiting longer… Link to comment Share on other sites More sharing options...
BoozeRS05 Posted January 6, 2023 Share Posted January 6, 2023 You’re fine to top off with anything decent, doesn’t HAVE to be the same weight even IMO. I’ve done it plenty. Being full is more important. Also the owner previous to me had the banjo bolt replaced instead of discarded on my car, but that was +10yrs ago and almost 90k miles. I wouldn’t worry about the banjo bolt if you’ve replaced it, although I’m strict at 3K-3.5k mile oil change intervals. 1 1 EB's Subaru journal - 2005 LegacyGT Wagon & 2014 Forester FB25 (2008 specB - RIP) IG@legacygtliving Link to comment Share on other sites More sharing options...

Jolbaru_LGT Posted January 17, 2023 Author Share Posted January 17, 2023 I added some high mileage Mobil 1 advanced full synthetic. 10w 40 I believe. Might be psychological but I swear it’s a tad smoother. Link to comment Share on other sites More sharing options...
silverton Posted January 17, 2023 Share Posted January 17, 2023 Depending on how low the oil was, that makes since. AVLS needs oil. Link to comment Share on other sites More sharing options...
