Oil Additives Solid Cam??

most cam manufacturers will tell you to NOT use synthetic oil on a flat cam, while it is recommended for a roller cam. i use vr-1 without a problem. i have read you only need it as a breaking oil,(probably depends on your spring pressure) but i continue to run it after the first oil change...small price to pay for peace of mind. BTW, i think it was around $5 a quart.
