bad fuel?

**philander** · October 27th, 2004 11:16 AM

Ako din, dapat ba talaga 95 Ron (Velocity, Blaze, XCS, Vortex Gold, etc.) ang ikakarga ko sa kotse?

I have Nissan GX 2004. Nakalagay sa manual eh dapat daw unleaded 95Ron, kung sakaling walang available na 95Ron, pwede magkarga ng 93Ron at pag may avaialble na 95ROn, kargahan kagad...

Do those octane booster fuel additives work ? Or are they just snake oil like those oil additives ?

and ang petron XCS and Petron UNLEADED din i think is the same... hehe anu difference sa additives nila?

all the while i thought mga leaded gasoline pa ang XCS and super premium to cater to those older vehicles hehe kahit na alam kong pinagbabawal na peace..

sir chieffy sorry sa OT

no problem...marketing scheme perhaps?

ipakarga nyo lang lang yung mas murang variant with the same RON...unleaded naman lahat iyan...sa probinsya na lang meron pang mga regular gasoline....

If the manual says 95, then i'll use 95

for the rest, siguro feel nyo engine nyo, especially under loaded condtions,,,,, if you detect signs of "pre-ignition ot "ping" (takatakatak..)...then shift to higher octane fuel...

if there's no pinging, then try a lower octane fuel...if it runs ok, even under load, then save your money and use that particular grade ...or go to lower octane until it shows pinging ...then go back to the higher grade. Now you would have identified the right octane for your engine......

my humble contribution po ....

use the lowest octane rating your car can run without pinging.. technically.. walang benefits in running a 98RON on an econocar....you're just burning a hole on your wallet.

ako i switch 95 and 93 RON every full tank.

dapat yata may list tayo ng blacklisted (from experience) gasoline stations...

sir chieffy, baka nga meron halo yung gasolina nila.. or baka talagang tsamba at meron problem sa engine parts..

since bad fuel na rin topic, add ko mga experience ko..

favorite ng parents ko yung Unioil sa A.bonifacio dahil mura kaya doon sila lagi pakarga ng diesel (for revo GL), then paghiramin ko ito ng weekend.. pakiramdam ko eh mahina ang hatak nya, pag pinapalagyan ko ng shell diesel, mararamdaman mo yung difference.. mas responsive ng konti yung revo GL.. laging ganito na-experience ko everytime na hinihiram ko revo nila (mga year 2001-2003)

sa 2.0 gas revo gsx, RON91 ang minimum based sa revo manual, petron unleaded lang lagi lagay ko and okay naman performance at walang tope or knocking sound, pero meron ako napansin, everytime na I step hard on the gas pedal at 3rd gear to reach 4000rpm (max 4800rpm) dahil overtaking, meron instance na parang kinakapos ng hangin for half a second lang or parang pumalya/jerk ng half a second but no decrease on speed.. ni-check ng casa ang timing and oks naman,

so i switched to petron XCS (ron95) and never encountered the half a second jerk.. don't know kung bakit ganon makina ng revo 2.0 ... also, i'm not saying na good fuel ang xcs.. haven't tried caltex gold or shell blaze..

ang pagkakaalam ko yung shell premium, xcs ehh may lead substitute..for oldies. sa mga carburated kunti lang benifits by using high octane..pero pag EFI especially with O2 sensor huge advantage...

Possible kaya na nilalagyan ng mix used oil yung petrol natin kasi nung nag bike ako mga almost a month na 11:30 pm punta ako select para bili ng sun edi manila bullitin, tapuz may nilalagay yung gas boy sa banker na ewan, ehh yung pinag kukunan nya yung drum ng used oil na may funnel twing na pang change oil... medyo mamadali ako kaya di ko na inusisa....sana may regular petrol test yung mga gas station gaya sa abroad...

hehe O/T

diba yung petrol/diesel reserve natin ehh good for almost 90days ata bat twing tataas yung world market after a day or a week taasan din yung oil company satin...Hmmm

negosyante talaga!

"Possible kaya na nilalagyan ng mix used oil yung petrol natin "

This is interesting.....you can do a simple test to check it..... place a few drops of gasoline on a glass plate and allow it to evaporate.........if oil is present , it will be left behind on the glass.......then it's time to complain...
