Engine Oil - All About It


Recommended Posts

well said sir. as a former shell guy you are right on the API rating. many oils in the market have both S ( for spark or gasoline ) and C ( for compression or diesel ) A{I ratings.

 

what do these letters mean ? an SB rated oil is better than and SA oil and a CB oil is better than a CA oil. right now we're pretty much advanced as we are now in CH / SL territories as oil companies like shell continue to develop higher quality engine oils to meet the standards of engine manufacturers.

 

but just a bit of clarification ... rimula was developed primarily as a diesel engine oil which can also be used for SL rated gas engines.helix ( the gas version) is primarily a gasoline engine oil which can also be used for diesel engines.The diff is that lies diesel engine oils have more detergents ( you read that right) that clean your engines as diesel is a "dirtier"fuel and produces more engine deposits than gasoline.

 

with that said ... will using rimula in a gas engine be harmful ? no . will it be better to use a gas engine oil like helix in a gas engine car ? yes. just my two cents.

 

diesel oil won't damage your engine but it will damage your catalytic converter.

Basta sa engine oil, important ang ilagay ang recommended oils sa car manual. Sundin rin ang recommended oil change interval. Pagkaka mineral, every 3-5k, pag semi-synthetic, every 7.5k at pagka fully synth every 10k ang standard rule at may differ among manufacturers. Basahin din ang label sa oil can. Ang fully synthetic usually namamatay 100% fully synthetic. Semi-synthetic at synthetic blend parehas lang. Sundin rin ang recommended grade ng oil as recommended sa car manual. Kung yung oil nakalagay sa label synthetic pero ubod ng mura, malamang hindi fully synthetic yun. Lastly, kung yung auto mo luma na at laging mineral ang nilalagay nyo, wag kayo mag synthetic, malamang tumagas yun.
