that's the oil companies marketing strategy claiming that using thick oil = wear engine protection where as thinner oil = improve FC. personally, I've already tried both oil viscosity for quite sometime but the FC difference is negligible.![]()
Exactly my point.
Motor Oil Viscosity Grades Explained in Layman's Terms
Oh ayan stockengine, layman's term na yan ha.
I agree, newer engines maybe better of with W30 oil than W40 when brand new FC wise. Kaso sa post mo kasi nung una parang sinasabi mo na hindi pwede sae40 eh. Eh nasa manual naman. Tska karamihan nang FC test ay sa mga bansa na may winter. Sa pinas na tropical country wala pa comprehensive study dyan. So yung FC gain na sinasabi mo, might just be irrelevant if you consider the cost of a w30 FS oil vs a w40 dino oil.Just saying. I might be wrong of course.
But if the car manual specifically says use only w30, then of course who am I to question that.

viscosity*100c is different between a 5w40 and a 15w40.
shell helix ultra 5w40 is 13.5 much lower than a rotella t6.

heres a link about oil and improved fuel economy...
What you need to know about next-gen engine oil | Farm Vehicles content from Farm Industry News
nakalagay sa manual ng sasakyan ko para daw gumaganda ang fuel consumption use 0w20 oil, kaso gamit ko RP 5w30.
less viscous yung engine oil na gamit, mas di hirap gumalaw yung mga engine parts.

compromise kasi yang fuel efficiency at engine protection... if you want them both, 0W-40 ang option mo. kaso 0W-40 only comes in Fully synthetic form, kaya mahal. pero it would be the best all around viscosity.
we want the first number to be 0W, so it flows without restriction like water during first start / dry starts, regardless kung meh winter o hindi( its not an issue na dapat bangitin),
as we drive around and the engine starts to warm up, we want the last number to be around 40W so that the "oil when hot doesn't behave like water" anymore , so that it provides adequate protection.
the goal is to have an oil that is thin(less viscous) during starting= less wear , more fuel efficient
the goal is to have an oil that is thick(more viscous) during hot normal engine temp =less wear and more protection
answer is 0w-40... problem is mahal nga ito. kaya we settle for other cheaper alternatives like 10w-40/5w-30 etc....

Anybody using idemitsu 5w30 or 5w40. San may stock bukod sa unioil? Thanks.
me before but I switched to casa oil. hirap maghanap halos lahat ng unioil branch ala pero last week napadaan ako sa san juan going to kalendong, madami raw silang stocks gallon & per liter din. try mo...
