Query: Great oil, good price

You might be able to pick up a few horsepower with this oil in your race car. It has less detergent and more zinc than other oils. The zinc is good for flat tappet cams and extreme-duty wear that race cars get, and the full-synthetic makes it nice and slick. Hopefully you're changing your race oil often, so the less detergent shouldn't be a problem.I use only Valvoline in all my cars, and can't go wrong with it.
