Hello, im about to do a service on my new rx7 and trying to find oil to put in but everywhere I have checked only stock synthetic or semi synthetic. Heard Castrol GTX is one of the better oils to get but again none seem to be mineral oil. any help would be much appreciated.
Halfrauds has mineral oil on the cheap. What I use always. Yellow bottle I believe.
i can only find a blue halfords branded 15w/40
