Styx189,
Bro, I just remembered, Jun promised to post the fuel consumption computation (formula) to help us compare savings in the long term. We all compute naman pero we agreed that it will help "standardize" computation and aid with comparisons.
Pa-remind na lang. Thanks!

By Donnabelle L. Gatdula
The Philippine Star 03/07/2006
The Philippine Biodiesel Association (TPBA) is disputing Chevron Philippines Inc.’s claim that coco-biodiesel has not been properly tested for commercial use.
"Biodiesels, which have been tested and accepted in many countries in Europe and in North America, were sourced from vegetable oil of even lesser stability than coconut oil," the TPBA said.
According to TPBA, these biodiesels, which are now being used extensively in those countries, have not caused widespread problems.
"There is, therefore, no reason to believe that the use of coco-ester in the same engine at only one percent will be of serious concern and does not deserve endorsement. Furthermore, ester from coconut fraction are already in use and sold by oil companies worldwide in more sensitive engines like jet engines," it said.
It added that "for many decades, polyol/di ester of C8/C10 cut had been the main ingredient of aviation lubricants. C8/C10 comes only from coconut and some from palm kernel as no other plant oil contains such a component. This alone indicates that the technical excellence of coco-ester had been tried, tested, and used for the past many decades."
While countering Chevron’s claims, the TPBA nevertheless welcomed the oil firm’s arguments, saying that this will open a venue for the association to answer the oil industry’s concerns.
"One thing about Chevron (formerly Caltex) is that they have been consistent in their position against any biofuel initiative from Day One – unlike those who say they support the CME program but do the opposite," it said.
"Much of the issues they present are echoes of the problems associated with rapeseed and soybean biodiesel which are quite different from coco-biodiesel. Such problems as bacterial growth, rust formation, corrosion, are results of high unsaturates of rapeseed and soybean (above 80 percent). These problems are non-existent in coco-biodiesel because CME is highly saturated (91 percent) and is therefore stable against oxidation, not prone to bacterial growth, and corrosion," the group said.
The group said "it is in fact more stable than conventional diesel. The fact that they are using the issues on rapeseed and soybean against coco-biodiesel simply indicate that they probably think all biodiesels are alike."
With this, the TPBA has urged the oil companies to join hands in pushing for the Biofuels Bill which will not only adhere to cheaper alternative fuels but also help clean the air.
"The Biofuels Bill is undoubtedly in the right direction since oil companies will never move into the development of green gold unless they have a commercial interest in it. This is evident in bioethanol which did not receive much obstruction from oil companies even at a five percent blend - because one of them is investing on a bioethanol plant," it said.
On the matter of government subsidy, the TPBA said this has never been a part of the national program and it is not the intention of government nor will it be favorable for government to put up a subsidy simply to ensure the success of the CME program.

More from inq7
LIKE the country's two other big oil companies, Chevron Philippines Inc. (formerly Caltex Philippines Inc.) is not keen on selling pre-blended coco-biodiesel directly from its pumps.
In a position paper submitted to the House of Representatives, the company expressed regret that it cannot support pending legislative bills that aim to make mandatory the sale and use of pre-blended coco-biodiesel.
Chevron said more tests had to be done on the fuel to make sure that it would not cause damage to storage tanks and vehicle engines.
It said coco methyl ester (CME) needs special handling procedures to ensure against bacterial growth in tanks.
"No tests have been conducted on the long-term effects of CME-blended diesel ... on our storage tanks, particularly whether [CME] will increase the rust and corrosion rate of the tanks," Chevron said. "Moreover, we are apprehensive that offering CME, a relatively untested product in Philippine conditions, [may] unduly exposes both our retailers and the company to consumer complaints and, worse, legal liability."
The company noted that the long-term effects of CME-blended diesel on vehicles' fuel injectors had yet to be determined. It said that in case of any malfunctions, it had not been made clear who would take the blame: the government, the oil companies or the retailers.
Chevron also said all the products it sells at its stations had undergone "a battery of tests the world over," but CME has yet to undergo enough tests to merit its endorsement.
"In view of all the foregoing ... we regret we cannot support the passage of these measures until our concerns have been addressed," Chevron said.
In an earlier interview, Petron Corp. president and chief executive Khalid Al-Faddagh said the oil refiner and distributor still had a lot of "technical concerns" on CME-blended diesel, especially if this would be sold directly from its dispensing pumps.
The country's other refiner, Pilipinas Shell Petroleum Corp., said that it wanted more tests to be done on CME.
One of Shell's concerns on selling CME has to do with the stability of the product, a company official said.Last edited by dx8976; March 7th, 2006 at 12:09 PM.

mas mataas yata ang standards ng Philippine oil companies kesa US and Europe who have been using biodiesel for a while now.
