Orig po ang Mobil1 na ginagamit po namin dati. We buy it from Tireboy Araneta. I have posted something in the MSCP forums yesterday. Let me share it.

My Monty's clocking 28k km already. I'm already nearing my 30k km PMS. Here are the oils I used before.

1. Turbo XP Synthetic Oil 15W-50 (1,000-20,000 km)
2. Royal Purple Synthetic Motor Oil 15W-40 (20,000-present km)

I'm thinking of trying Motul CRDi Specific Synthetic Oil 5W-40 for the 30,000 km PMS. But my dad and mom wants me to clarify if we can use Motul CRDi Specific for the 30k km PMS. They told me to consult the warranty booklet and call Mitsubishi Motors Philippines. Here's what I saw in the warranty booklet:



Also, I called MMPC at 10 am this morning. I talked with Mr. Ron Brosas, one of their technical staff. I asked him if the right SAE Nos. for the Monty and Strada is the one I saw in the warranty booklet. He answered me in the affirmative. He then explained that due to our tropical climate, dapat malapot ang oil na ginagamit natin. I then asked him what if I use an engine oil with a SAE No. lower than 15W-40. He then explained that using an engine oil with SAE Nos. 0W-30, 5W-40, 10W-40 etc., anything lower than 15W-40, is malabnaw. And an engine oil which is malabnaw is bad for our engine running in a tropical climate. The 4M41 and the 4D56 are high performance engines according to him. Using an engine oil that is malabnaw will not properly lubricate the mechanical parts of our engines. Madidikit agad ang mga mechanical parts ng engine if we use an engine oil with an SAE No. lower than 15W-40. It might probably cause the premature knocking of our engines according to him. Due to our tropical climate, MMPC recommends using oils with SAE Nos. depicted in the image above. Also, they have given permission to their dealers that customers can bring their own oil as long as the oil is within their specifications. They also told their dealers to strongly discourage their customers to use engine oils with a SAE No. lower than 15W-40.
