im looking at doing a service just changing oil, oil filter and fuel filter.
in the workshop manual advises 7.6l 5w30 cf-4 so i go in to auto shop and when the guy looked up in his manual for d40 yd25 it advises magnatec 5w40
prev mechanic used caltex delo 500 (not sure what W it was..i tink its 10w30)
also was adivsed that once using fully synthetic u cant go back to thinner oil. is this true?
