Mineral , semi synthetic or fully synthetic?

So a CI-4 rated mineral oil is much better than a CH-4/CF-4 rated synthetic oil sir?

Just my 2c, depende siguro kung anu requirement ng engine mo. Not factoring the price, kung CI4 ang kailangan ( such as those with egr) mas gagamitin ko yung CI4 rated na mineral kesa sa CH4 na synthetic. Same is true sa mga CJ4 rated oils, kung di ULSD gamit ko at wala naman DPF I would prefer a CI4 or CI4 plus rated oil because generally they have higher TBNs than the CJ4s. Pero kung CH4 lng kailangan ng engine ko and I am after better protection I would probably go for the CH4 synthetic than a CI4 mineral (unless cguro kung Delo 400 ;) )
