Lumakas ang FC after change oil

**radz15** · January 31st, 2014 09:12 PM

Guys ask ko lang normal lang ba na tumaas ang FC kada change oil especially fully synthetic? Dating mineral oil gamit ko (shell rimula) nung nagpalit ako ng Royal purple synthetic oil pansin ko tumaas yung FC ko. Kada full tank kasi average ko 550KM pero nag drop sya sa 450KM then after 3 full tank bumalik na uli sa normal FC ko. Tas ngayon nag change oil uli ako from RP, S-Oil fully synthetic na gamit ko. From the usual 550KM nag drop uli around 440-450KM. Normal lang ba talaga to? Btw 2011 adventure auto ko. Thanks!

Nagbawas ba ng langis?

Kung luma na ang sasakyan at mataas ang mileage, stick to mineral then change oil every 5k kms.

Nagkakaroon ng sealing probs at leakage kapag synthetic ginamit sa lumang makina dahil mas maliit ang molecules.

Pag sinabing lumang makina mga ilan mileage pinag uusapan natin? 50k up considered luma na ba?

Pag lumampas na ng warrenty, consider the car as luma na. 100k kms.. Kung nasimulan sa mineral oil, as much as possible stick to mineral oil. Kung walang sealing problems, then proceed using synth.

Just sayin based from experience running a fleet.

Imo nababawasan ang viscosity ng langis o nagiging manipis habang tumatagal. Pag nipis nito ang epekto kadalasan ang pag ganda ng fc. Ilan po ba viscosity ng langis na nilagay nyo? Sa experience ko naman sa royal purple mas naging matipid dahil mas naging responsive makina sa pakiramdam ko.

Afaik pag synthetic gamit mas consistent ang viscosity ng langis over time compared to mineral.

Had the same experience also running RP on my Altis. Gumanda ang hatak pero bumagsak ang FC. From my average of 9.2km/l to 9.8km/l bumaba sa 8.4~9.0km/l na lang. Pero in fairness sa RP, ganundin naging FC ko sa Idemitsu. Back to the Toyota 5W40 fully synthetic and balik din sa dati ang FC ko.

Sir anong viscosity ang gamit mo before sa Idemitsu 5W 30 or 5W 40? TIA

I think 5W-30 yata. Me Unioil kasi dito sa Marikina so doon ako nagpa-change oil with Idemitsu. Sinubukan ko mas malabnaw kesa sa 5W-40 ng Toyota. 5W-30 din yung RP before kaya taka nga rin ako bakit mas worse ang FC ko. Balik ulit ako sa Toyota 5W-40 FS at nakakaabot na ulit ng mga 9.6-9.8km/lit.

Pansin ko rin nga pala kapag medyo luma/matagal na yung oil parang mas nagiging consistent na mas maganda ang FC figure.

Sir 40k ko sya sinimulang gawing synthetic. 50k na yung auto ko ngayon. Wala naman syang sealing problem
