i ran all current season on that oil since spring and had oil level reduced by 1 line only. did 3 DE days so far as well. IMHO it is a normal usage for one oil cycle. I was told to change oil after each 5-6 DE events and it looks to be most likely to be exactly as much for me per season in average, so, regular 2 annual oil changes will still fit, perhaps with moving spring oil change more into summer as 5w50 is OK for track as well.

i guess best shot would be if you could use that different brand and post here results - who knows, may be for sure mobil 1 is now a POS oil and really behaves much worse than its competitors. I guess only way to find out is to test it.

I am blowing through my last M1 oil, but allways change after 500 miles or less. Make sure you add a ZDDP additive with your M1 store bought oil. My mechanic has been aware of this topic since 05 and seen multiple scored cams from M1 only filled engines. Store bought and whats going into the flying Lizard are different animals. I understand Motul has product in 5 qrt package, which should also be reasonable in price.

Fine for street cars, not my race cars.
For awhile I used the mobil 1 0w-40 mixed with the Mobil 1 V-twin 20/50 motorcycle oil that has extra zddp in it. Then I decided to abandon it all together for track use.
There is a real good Mobil 1 racing oil (likely what FL is using) but its around $15 a quart I believe
