They certainly won’t hurt. Until they fall apart. For a strip only car the time spent at wide open full boost the oilers don’t do much in my opinion. Hell with twins and a hot tune up, your run probably only lasts 8 seconds. Detonation is a much bigger concern. Of course I could be proven wrong. For a half mile car or a road course car I could see a big benefit to having them and would call it a necessity.
