I switched to Brad Penn shortly after break-in, largely due to Patrick's experience with it and further research I did. Its cheaper than Valvoline (call American Refining and ask for your local dealer), its available in a wider variety of weights and you don't have to worry with an additive. This is what was orginally Kendall GT-1 Racing
Oil. Oh, and if your FE likes pissing on the floor, its easy to spot a leak because its greeeeeen.
