[QUOTE="UnleashedBeast, post: 12814989, member: 112023"] Thank you for the UOA. Horizon is another blanket name for Polaris Labs. Yep, seems you forgot to tell them "ATM 10W-30" so they knew exactly which formulation you were using. Wear metals are in check, despite your "rough" use of the car. This lubricant held up like a champ. Only 26 ppm of iron after your driving style is impressive. I'd sure love to know how Motorcraft 5W-20 would have responded to the same situation. Not as well I'd bet. Viscosity didn't shear at all. This is why I love the durability of Amsoil ATM 10W-30. You can't wear this stuff down easily. TBN is a bit lower than expected for the mileage. I would have expected it to be in the 5 range. No alarm here, as the lubricant still had active additives remaining when you changed it. Overall a great looking UOA. Your engine likes this lube.
