5wXX vs 10wXX vs 15wXX on cold start protection

[Martz1977]

Maybe sir you are right, dapat SAE 40 na lang dito sa Philippines, but this is not what our car manual is telling us especially for new engine, maybe the Car manufacturer is just too conservative in telling us what oil to use here in the philippines, beside they don't even know in which part of the world that our car maybe used or exported. If you want to know how the first number and letter differ from each other in terms of functionality, the link below might help you,

But again, AFAIK, sae40, 0w-40, 5w-40, 10w-40 and 15w-40 oils will just flow in the same manner here in our country considering an ambient temperature of 30 degrees centigrade kahit pa cold start, kasi nga eh nakikita mo naman yung oil condition sa container nya with an ambient temperature here in the philippines, definitely, sa loob ng engine ay ganuon pa rin ang condition nya. Siguro nga ay sa additives na lang nagkakatalo ang different oil brands.

Thanks sir for the video. I could imagine that there wont be much significant difference in lubricating the engine in our condition for 5w vs 15w since both will reach vital parts fast. Maybe it is the fuel economy that would be benificial for lower w rating while warming up, which is just +/-5 min. Im off to get the delo400 then.

Me too sir, I am also eyeing for that Delo 400 for my next oil change, coming from 15w-40 RP Oil....
