read yr experience with caltex,
infact i had the same feeling after switch from mobil 95(using for 2yr plus) to mobil 98(3 mnths) then to caltex 98 (2mths till now). Feel the car more responsive, quieter and no-more engine pinging.
Guess i will using with caltex 98 for a while longer.....

My Latio does not have pinging or knocking sound on Esso 95.
Your car may have some faults. Send it to tan Chong for a check.
Latio can accept even 92RON.

is ur mileage on caltex consistent? i wana try.. cos my mileage on esso same as yours. hv u tried esso 98 and caltex 98 as well?

Hi gunner, yes, my mileage on caltex is constant.
I actually begin Caltex.
Then i switch to Esso/Mobil, use Citibank Dividend to accumulate up to $50 rebate to get the cheque. That is the time when i notice mileage deteriorates.
After i accumulated the $50 for my dividend card, i switch back to caltex and got back my prev FC....

yup, they are all about the same. used to work at Caltex and my colleagues told me these:
from Mr A (retail): of course on a personal basis, else he will loose his job... hahahaha :D
RON92 = RON92, RON95 = RON95, RON98 = RON98
differences are in the additives (e.g. cleaning agents to clear the injectors and piston head, aid combustion, etc) and color dyes (that's why some red, some green, some yellow in color) added to support marketing claims of "cleaner greener" gasoline.
we’re basically paying a lot more for a little bit differential gain :bleh:
from Mr B (oil trading): much more technical
although RON levels may be the same, geographical source of the crude makes a difference. crude extracted from different regions have different compositions of hydrocarbon and thus affects the “quality” and pricing of gasoline derived.
the petroleum industry generally classifies crude oil by the geographic source (e.g. saudi, russia, malaysia, etc.), its API gravity (density), and by its sulfur content. crude is considered light if it has low density (heavy if high density) and categorized as sweet if it contains relatively little sulfur, or sour if it contains substantial amounts of sulfur.
light crude is more desirable as it produces a higher yield of gasoline, sweet crude requires less refining to reduce sulfur contents (there are controls to max sulfur levels allowable to meet environmental standards).
problem is, we won't get to know where the gasoline is from which crude source unless we are “insiders” :crying:

currently using esso out of convenience and 5%+5% discount... nearest kiosk is only about 200+m away from my house. with esso-dbs mastercard + speedpass, i get 10% discount and lots of convenience.
tried synergy 2000, 5000 and 8000 but settled down with 5000 as it gave best value on response, FC and price. used to pump platinum and sometimes v-power but they're way toooo expensive in Sg... MY no issue :D

Wondering is SG Esso 5000 the same as JB Esso 5000.
Will they be any damage if we pump slightly more petrol after the pump has triggered full.
