Mineral , semi synthetic or fully synthetic?

[nivraarvin]

Here's another issue for our discussion purposes only. Why not use 5W-40 instead of 5W-30 in Baguio? Based on the above mentioned pixs using 5W-30 is a good starting in cold weather where as a higher viscosity oil is to properly lubricate the engine, meaning better protection.....

A higher SAE grade does not always mean "better" protection.

Higher SAE grades are used for elevated engine temperature, for example, endurance racing.

The car's cooling system maintains a minimum and maximum temperature. It does not matter what oil you use, 5W30 and 5W40 will have the same operating temperature.

Here in the Philippines, including Baguio, the oil's cold flow grade (5W) is not that important.

San kayo naka bili ng mobil delvac mx sa Banawe? Sinuyod ko kanina, wala ako makita, meron man display, out of stock...

May nakita ako 220/liter pero Monograde naman...

mukang sa mall nako bibili ah..

ang mahal naman yan sir. 220 monograde lang? sa ace ka na lang bumili sir pag may sale doon 10% discount.

[ronki]

para sa vios mo? ayaw mo na sa DGU?

Yes sir, try lang delvac

Nakabili nako sa ace, 249.75 isa.

Ngayon problema ko san pwede mag pa change oil / clean brakes na din na labor lang...

[Retz]

^

pwede na sa gas station sir kung un lang papagawa mo.

Okay ba ang Delvac sa Vios?

ok lang yan sir...

kahit anong grade pa pwede gamitin, kasi hindi naman nag wi-winter dito... so kahit 0W/5W/10W/15W ang start it will have the same protection... the difference in flow characteristics is marginal because we never get so cold here...
preference and budget lang mag determine kung anu bibilin para sa auto.

kapag cold weather(winter) 15w40 won't flow even 10W will have a hard time before flowing,

"the difference will be in fuel efficiency, 0W/5W are more fuel efficient compared to higher grades"

tanong ko lang Sir.

yung "cold" viscosity ng 0w40 na Mobil ay 75 cSt, "hot" naman ay 13.5 cSt

yung sa 15w40 na Mobil din ang "cold" niya 109 cSt, "hot" naman ay 14.5 cSt

kung marginal lang ang difference during cold flow, ilang percentage ba ang pinagkaiba ng 75 cSt sa 109 cSt?

base kasi dun sa datasheet, halos same lang sila ng viscosity during operating temperature. 1 cSt lang ang pinagkaiba nila.

sabi din kasi ni pareng Google, 80% ng engine wear nasa initial start up.

salamat.

Lalu na siguro if you use monograde SAE 40, Like they have in Petron.

Kung wala naman fuel or coolant dilution sa motor oil, hindi naman mawala totally ang wear protection additives ng oil sa mga bearing surfaces ng engine. Considering the ambient temperature natin, kahit 15W40 pa ang motor oil use, it will easily flow where it is needed. CS will tell us, mas mabilis siempre flow ang 0W40 or 5W40 dahil mas malabnaw pero viscosity difference at operating temp is really negligible. Best is to warm up the engine at idle for 3 - 5 minutes before you go on your daily grind.

CST reflects the time required for a fixed amount of fluid to flow through a certain sized orifice on the testing device

bro, it may seem technical and overwhelming yung info and numbers, its just says na kapag mas malapot ang oil mas matagal siya makapasok sa butas... lalapot siya kung malamig ang ambient temperature... eh kahit nasa baguio pa tayo eh hindi yan aabot sa freezing temp, so it will still flow sa orifices just a little bit slower if not almost the same to 0W to 5W...

we can never eliminate engine wear during start up, unless meh mainbento na oil na hindi mag settle sa oil pan...
its like us humans, we age we get sick... so ganun din engines, it will get old and will have breakdowns.

kung meh budget ka go for fully synthetics... and dapat dilemma is to go fully synthetics or not,
hindi na dapat pag isipan nang malalim kung 5w/10w/15w... "unless you want fuel efficiency"
