Hi. Petron Rev-X Trekker is a very good diesel engine oil. I have been using it for the past 8 years on my aging 10 year old Strada. So far no problems. I once forgot to change my oil for 10,000 still my 4D56 engine ran smoothly. Mas maitim lang nga ang oil ng mag-palit ako. I have trusted this API-CI4 oil for the past 8 years and would gladly use it on my new Montero Sport 4D56 engine. The oil is not at fault. Probably baradong oil filter in the mentioned engine or something else.
