With the sticker shock that's hit Blackstone and SpeedDiagnostic I've decided to try out Hot Shot's Oil analysis. For four kits my total bill I believe was $93. You can google a discount code and it took 15% off. Worth a look if you don't feel like paying $50-$60 a pop. I'll can't attest to their quality but we'll see. Going to do a VOA here in a few days then monitor my usage of Redline 5w30 in my B58. The only negative I've heard of Redline is the pricing. So I went with FCPEuro and just going to do it for the price of shipping.
