Well I am not in the Philippines not until next year. But the oils I like there are the Rottela, Motul, and Mobil Delvac if you can get it.
But I like mine high in zinc if you see CI-4 Plus rating on it snap it up it's getting very rare and is very high in zinc, I was lucky Mobil has stopped making this but on base here it's on deep discount for the Mobil Delvac super 1300, in pesos it would be 225P for 1 gallon

I got a bunch which I will send over when I move there.
But here is some stuff you can look for in a good diesel oil Mobile Delvac super for instance has the API service rating of CJ-4, CI-4 Plus, (new formula does not) CI-4, CH-4, CF/SM/SL plus a bunch of other manufacture ratings.
Here's how to look at these ratings.
SM – 2004 Gasoline Engine Service – For all automotive engines currently in use. Introduced in 2004, SM oils are designed to provide improved oxidation resistance, improved deposit protection, better wear protection, and better low-temperature performance over the life of the oil. Some SM oils may also meet the latest ILSAC specification and/or qualify as Energy conserving.
SL – 2001 Gasoline Engine Service – Category SL was adopted to describe engine oils for use in 2001. It is for use in service typical of gasoline engines in present and earlier passenger cars, sport utility vehicles, vans and light trucks operating under vehicle manufacturers’ recommended maintenance procedures. They may be used where API Service Category SJ and earlier categories are recommended.
CF – Indirect Injected Diesel Engine Service – Service typical of indirect injected diesel engines and other diesel engines that use a broad range of fuel types, including those using fuel with sulfur content above 0.5%. Requirements include control of piston deposits, wear and bearing corrosion. Engines may be naturally aspirated, turbocharged or supercharged. CF rated oils may be used when API CD oils are called for.
CI-4 – 2002 Severe-Duty Diesel Engine Service – The API CI-4 Service category describes oils for use in those high-speed, four-stroke cycle diesel engines designed to meet 2004 exhaust emission standards, to be implemented October 2002. These oils are compounded for use in all applications with diesel fuels ranging in sulfur content up to 0.05% by weight. These oils are especially effective at sustaining engine durability where Exhaust Gas Recirculation (EGR) and other exhaust emission componentry may be used. Optimum protection is provided for control of corrosive wear tendencies, low and high temperature stability, soot handling properties, piston deposit control, valvetrain wear, oxidative thickening, foaming and viscosity loss due to shear. API CI-4 oils can effectively lubricate engines calling for API CH-4, CG-4 and CF-4 Service Categories.
CJ-4 – 2006 Heavy Duty Diesel Engine Service; Exhaust Aftertreatment – Introduced in 2006. For high-speed, four-stroke engines designed to meet 2007 model year on-highway exhaust emission standards. CJ-4 oils are compounded for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). However, use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact exhaust aftertreatment system durability and/or oil drain interval. CJ-4 oils are effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. Optimum protection is provided for control of catalyst poisoning, particulate filter blocking, engine wear, piston deposits, low and high temperature stability, soot handling properties, oxidative thickening, foaming, and viscosity loss due to shear. API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4 PLUS, CI-4, CH-4, CG-4, and CF-4 and can effectively lubricate engines calling for those API Service Categories. When using CJ-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval.
I car more about what's in the oil the what the brand is, I won't use anything without the API rating simply because you don't know what your getting. Now if your using regular car oil in your diesel it's probably just SM rated, but using diesel oil in a gas engine is never a bad thing it offers more protection, better lubrication and have better cleaning and anti corrosion additives as well as anti wear additives.
