hey guys i just have a quick question at the moment i have an 18rc with the shitty 3 speed auto am i right to assume that because the engine has to rev about 3600-3800 rpm on the freeway that my oil will be breaking down and burning like a mofo? would a simple ra40 4 speed auto fix this i only ask because its really bad like 4l oil every 400ks i dont want to kill the planet. Anyhow jsut so u know its not going manual because i plan on geting another car at christmas
