Thank you for the info! Unfortunately the only NAPA we had closed a couple years ago. Next closest is about 90 miles away. Kind of surprising that it closed since we have 3 Advanced Auto's, 3 O'Reilly's and 2 Autozone's among other smaller parts stores. Not that a population of 130k-ish is big, but certainly not a small town.
With Euro oils not having API SN/SN+ or ISLAC GF6A ratings, is there a cross ref between their ACEA ratings that are equivalents or any reason for concern? I know Euro requirements are generally more strict and I don't really have any real concerns, its more out of curiosity.
I really don't have any qualms with using a 5w30 for the most part. But in my area we can range anywhere from -20F to 100F and I prefer a 0wXX for cold starts and so I'm not changing oil for seasons. I know it's an irrational thought, just the way I am. haha To my knowledge 0wXX oils tend to be more shear resistant than 5wXX oils from my research. I could be completely wrong, I am all ears if I am.
I suppose if I don't find an oil that I am comfortable with going 5k on, I will likely just shorten the OCI to 4k or even 3k. We normally don't as much as we did last year, usually it's about 10k a yr. So shorter OCI's wouldn't be a deal breaker. It still surprises me how hard this engine is on an oil like M1 EP compared to others that have run that oil to 10k OCI's in other cars without the same amount of shearing.
