Interesting I didn't see that. So as you are using grade 30 did it affect your mileage. I know it's irrelevant to you as you are tuned and driving it pretty hardWell mostly because I live in hot climate and I prefer the heavier weight over the water thin 0-20. Plus @k20z3allmotor who works on these motors all the time recommended it for people who are doing more than just daily driving. Im tuned and I run my car pretty hard. And lastly,0-20 is literally for EPA CAFE standards and MPGs. If you read the owners manuals for Euro cars, it specifically says if 0-20 isnt available 5-30 is fine. Now I'm not making any recommendations to anyone or saying one is better than the other but I believe my Oil Analysis, whether you agree with how fuel dilution is tested or not, still shows my engine to be in great shape
