no... and it would be best to convert the WVO to bio-diesel & blended it in 50/50 with regular diesel before using it in your CRDI engine.

The impurities and particulates in waste vegetable oil make it unsuitable for use in CRDi engines, even if you filter it.

It might be possible to strain the oil with a 1-micron filter, but even then, there's no assurance that the contaminants and/or water content will not damage your pump and/or injectors.

Best to convert it to Biodiesel, but I've heard that this may have an unwanted effect on the valves of ordinary diesel engines if you use 100% Biodiesel.

Hence the advise to use a 50/50 blend of bio-diesel with regular diesel.

hello bonjour, i am so sorry for reviving this 10 year old thread...
firstly i am not lucky enough to be a Pilipinoe.. i am Canadiano.. i live in Tacloban city and i have full intentions to buy a 2012 toyota Fortuner next month kasi they dont exist in my malamig country.. and for nearly 20 years ive fantasized about driving a diesel and using waste cooking oil.. moving around your beautiful country at zero cost.. (kasi i grew up a palaboy in Canada).. i believe the best cars (that need zero modification) is Mercees 300D, 240D and finally 200D.. 1984.. however.. if i start egine and cut engine using only WVO will form Caramelization inside the cylinder and on top of the piston so a conversion kit is heavily advised... so.. since i absolutely need a wvo (conversion kit).. i dont REALLY need a 1984 mercedes which uses IDI.. indirect diesel injection..so.. F it.. ill get the 2012 toyota Fortuner here in Leyte.. it has a D4D engine.. which uses CRDI.. common rail diesel Injection.. so finally here is my question.. is there a garage somewhere in i dont know.. Luzon maybe that installs a generic waste cooking oil kit.. beause the kits sold online are buang prices.. 2000$us... .. i am positive there is a mechanic somewhere in this super intelligent country that can do this at a much lower cost... most of the parts are universal. a long hose from engine block to the boot (trunk in my igit country..).. an aluminium secondary tank to store the wvo (waste cooking oil).. a switch to change fuel to engine from wvo to diesel and reverse.. the only part that i imagine would cost anything is the relay for the switch.. do any of you know a mechanic in your brgy that can get all these simple parts and duct tape everything into my first ever SUV ???

salamat and amping

I don't know.... The fact that even if you only use quality straight Diesel fuel from reputable gas stations does not exempt you from running into occasional fuel system issues like carbon buildup and clogged injectors. Much more if you use a fuel source which aren't made specifically for internal combustion engines.

Maybe if I was using an old-school, non-CRDI engine, I'll probably consider WVO as a viable fuel source. However, most modern CRDIs and emissions systems above EURO II are just too unforgiving in terms of fuel quality, IMO. They will run on WVO sure, but long-term engine durability and reliability may not be what one might expect. And if issues arise, the high-pressure fuel system (pump, SCV, injectors) are also very expensive to service, repair, or replace. The penny saved on fuel can quickly translate to a significant repair bill later.

wow thank you for your very informative reply, should i stick with the old 80's Mercedes to have this car last the longest, but im positive if my umm driveshaft ? snaps again like it did it on my probe GT back in Canda.. my entire brgy will hear me screaming and swearing in Quebecois if i try to pull it out of the transmissission... i fully intend to take a few carferry rides from leyte to Cebu... there is a Canadian fast food burger place there called Harveys that i miss so so much.. and during that boat ride. if im permitted, id like to sit in my vehicle with the aircon on.. problem with that is that i am a cheap b4stard... and to run AC the motor nees to be running... but if i have wvo.. i wont care

may i ask.. how long till i actually see engine damage from WVO usage ? 5 years ? 10 years ??? by then i will most likely have that bobo Canadian electric car.. the umm Tesla ???

Marc, is that you who said all those nice things? Really appreciate it. Hope all is well in Milan.

To: Baludoy, yes I am the guy that appeared in the Rock Ed program. Gang Badoy is a friend and is helping me promote this environmentally friendly technology.

To: MBeige, I'm sorry to hear that Lovecraft is causing a lot of havoc and giving SVO a bad name. There are many copy cats that do not know what they are doing. There are certainly a few people here that have tried to copy my technology without really understanding it. For example, when I did my first conversion, Sunshine Motors (a Mercedes Benz shop in QC) copied me without really understanding. So they tried to sell their version at double my price and not teaching you how to filter your own fuel. There are many outfits in the US that are doing this, and offer WVO filtering systems that do not work. I actually bought one (Dieselcraft) which was very expensive and did nothing to filter it which gave me major problems. So I decided to develop my own.

I have been running on WVO fuel for 2.5 years now without problem. My fuel is cleaner than the diesel that is available here. If you are worried, I offer a warranty. I will fix anything that breaks if it is because of Alterenergy's SVO system.

I have converted an MB300D, Mitsubishi Canter, Pajero 1990, 4 Isuzu Elfs, MB300SDL, Toyota Land Cruiser (Subic), 2 MB240D's, Ford Ranger 2005, etc. My fuel is now at P20/liter

Fuel supply is tough as many restaurants offer their oil for sale for a high price. The people who buy at this price re-use the oil for human consumption such as chicharon and hopia production, or sell this carcinogenic oil in the public markets as new cooking oil. Just this morning I saw a Max Fried Chicken store in Magallanes selling their oil. I asked the buyer what he was using it for. He said fish crackers. Though I have enough fuel for individuals, I don't have enough for a fleet of trucks.

If you own a restaurant or a chain of fast food restos, and have delivery trucks, you would be my ideal customer and supplier of oil. Please don't sell your oil to just anybody. You might be giving people cancer by doing so.

Please do call me if you are interested.

I've been advocating this technology to help prevent global warming. I was criticized to be an alarmist, by taking advantage of Typhoon Millenio. Now Typhoon Ondoy and Pepeng came. Should I just keep my mouth shut, when I have a technology that will help?

The country generates 250 million liters of used cooking oil per year. This goes into our food or into our canals which end up in the ocean. We can use this to save the environment. I hope people will care this time.

I as a Canadian environmental list completely view with you and yes your post might have been before or after typhoon yolanda regardless even McDonald's in the Philippines surrenender all their used cooking oil to the police force of the Philippines so they are driving on used cooking oil if you are not aware

worth mentioning.. that diesel is a gasoline production byproduct.. and WVO has alot less emissions than actual diesel... so.. if im ever caught driving wvo.. i expect a sweet postcard from EURO II thanking me for my efforts.. .. furthermore.. all jeepneys in the Philippines were or are diesel since the US occupation... if my wvo is bad in anyway.. it is a tiny drop compared to the black smoke coming from Jeeps i saw on Mcarthur hwy in Caridad Cavite..
