I have been in Nitro RC'ing for about 4 years and keep getting different information on how to ust the after run oil. I just pre-order the new Nitro Rustler and I want to keep the 2.5 in great shape. Let me know when you use after run oil and how you use it. My LHS is a bunch of jerks, who I cream when we race. So they do not like to help me much. Thanks.
