Unleaded Gasoline [Merged]

[onewaytrip]

dati palaging blaze or velocity or gold ang gamit ko. pati sa liteace. tapos nabasa ko sa owner's manual 90 lang pala ang kailangang octane. kaya ngayon super premium (93) na lang. sayang lang ba o may benefit pa rin pag gumamit ng 95 octane?

nabasa ko sa isa pang automotive site na may bad effects ang Blaze. mula nun Velocity na ginamit ko sa corona (sabi sa owner's manual 95 octane). imo ramdam ang difference kumpara sa 93 octane.

I think your gas there is over-rated....most jap cars i've seen here only runs using cheap gas (aka 87 octane)....the majority of manufacturers that uses high octane gas (92 or 93) are european cars because they use hi-compression engines....and hi-octane gas is only recommended to avoid engine knock.....i think the philippine government should be more strict with all these gas stations because they could easily cheat with their ratings.....and that is plain stealing from the consumers...

that's because the US & Canada have a different octane rating from the rest of the world.

The US/Canada uses a different Octane rating system at the
gas pumps than most other countries.

They use the U.S. Cost of Living Council (CLC) index
which is the average of the Research Octane Number (RON) and
the Motor Octane Number (MON):


CLC = (RON + MON) / 2

RON = Research Octane number (ROZ in Germany)
MON = Motor Octane Number
CLC = U.S. Cost of Living Council

This translates to (roughly):

91 RON = 87 CLC (Regular)
95 RON = 91 CLC (Premium)
