A question for Amsoil if I may.
I have recently sold my Laguna Initiale, 2.0 petrol engine, because of severe electronic problems, although I still follow this site. I have replaced it with a 2.2 diesel X Type Jaguar. Do the same concerns in respect of fully synthetic oils vis-a-vis other oils apply to other diesel engines, or is it confined specifically to Renault engines? My dealer says they use the
recommended by Jaguar which is 5w-30w, I think.
change intervals be less than the recommended service at 12000 miles? If so , should I be insisting on fully synthetic
, which I would cheerfully pay for if it preserves the integrity of the engine. I have tried posting this question and concerns on the Jaguar Forum but do not seem to be able to get a suitable or knowledgable reply.
I would be grateful for a response and thank the moderators for allowing me to ask a non-Renault question.
