I think I’ll give the 300v a try. It’s like $170 for 8 liters with tax from fcp euro. I only do about 6000 miles a year but usually hit the track 8-10 times a year. Need to get at least 3 oil changes out of the initial $170 purchase to make it worthwhile. Like I said I’m my previous post I had good oil reports from black stone with castrol edge 0w-40 but I also love free oil changes and if I can put a much better oil for the same money as I’d spend at Walmart why not?
