The San Francisco Bay Area and Northern California has thousands of restaurants who end up with massive amounts of used fats, cooking oil, and grease (F.O.G.) from their fryers. In the past Restaurateurs paid to remove this FOG from their establishments, but now-a-days, there are many companies competing to collect this valuable commodity and pay the restaurateurs cold hard cash for the privilege.

Used cooking oil is a valuable resource for the BioFuels industry, where it is most often converted to BioDiesel through a chemical process called trans esterfication. Old cooking oil is filtered, dried to remove water, and then heated and combined with a catalyst, separated into glycerine, and BioDiesel, washed and dried, and then used in Diesel Vehicles for fuel. This is perhaps the best use of fats, oils, and grease, since the old cooking oil is removed from the food chain.

Other uses for used restaurant fryer oil is for animal fattening in feed lots just before slaughter. The animals are fed a potent mixer of rendered animals, and fats and corn for increased caloric intake. This feed is actually toxic to the animals if they are fed it for an extended period. Also, you have to wonder about the effects on animal fed food made from it’s own kind, and being fed something no longer considered fit for human consumption. I think used cooking oil is best used locally as biodiesel feed stock.

I have been burning BioDiesel in my 97 Dodge Ram for about a year and a half now. The truck loves the stuff, and I love it because I’m doing something to reduce pollution. BioDiesel is about 70% less polluting than regular diesel, and it’s non-toxic compared to the very toxic dino diesel.

Trying to buy BioDiesel in the San Francisco Bay Area would appear to be not quite so easy. But there is an SFBay producer of BioDiesel called Sirona Fuels, aka Blue Sky BioFuels who also sells locally produced BioDiesel at their Oakland, California location. You can buy biodiesel in sfbay at reasonable prices that often are less expensive than Dino Diesel. Sirona produces Biodiesel that meets and exceeds ASTM Specifications. ASTM Standards insure that BioDiesel is of the highest quality. See ASTM Standards for BioDiesel for more information.

Sirona Fuels is centrally located in Northern California, SFBay, Oakland, and is easily accessible for businesses and individuals in all of the San Francisco Bay Area. So if you live in the bay area and need free Recycling of fats, oil, and grease in San Francisco, then you should contact Sirona for free grease pickup, and if you have grease traps, Sirona can give you a quote on cleaning these.

Sirona Fuels is the only commercial producer of BioFuels in the SF Bay, and in addition to selling Biodiesel to both commercial and retail customers in Northern California, Sirona Fuels also buys and accepts donations of used fats, cooking oil and grease from Bay Area restaurants. Sirona Fuels removes it from the food chain and recycles it into biodiesel. Sirona helps make the greater San Francisco Bay Area a cleaner and healthier environment.

Sirona Fuels has Free collection and recycling of Used Fats, Cooking Oil, and Grease in San Francisco, and throughout the San Francisco Bay Area, and in the Following Northern California Locations:

It’s almost Thanksgiving, and Christmas will soon follow. During this holiday season a lot of folks fry up Turkeys. After the Turkeys get fried, the oil very often gets dumped down the drain, clogging up pipes, or it goes to the land fill or sits outside or in a garage until it festers. Don’t waste this valuable resource. Recycle your used turkey fry oil!.

I have had Fried Turkey, and it’s to die for. Great stuff, crispy on the outside and moist and tender for both the white meat and the dark meat. Most of the time it appears that the cooking oil gets used once and then it get disposed up in a less than environmental way. It’s a shame, since the oil is not at all used up and simple filtering will allow many other Turkeys to get fried.

Once the oil is ready to be recycled, it can be filtered, dried to remove any water, and then converted to Bio Diesel . BioDiesel is as much as 70% less polluting than Dino Diesel, and is non toxic contrary to normal Diesel. It’s a good thing to recycle your used cooking oil that you cooked your Turkey in.

Many times used cooking oil, especially that which comes from Restaurants gets put back into the food chain. Companies that Render the used oil use it to supplement animal feed. Many times this oil is rancid and contaminated by harsh cleaning chemicals by the time the rendering company picks up the used restaurant oil.

I’ve been running BioDiesel over the past year and a half in my 97 Dodge Diesel. The truck loves it, the exhaust has a pleasant frier aroma, and I feel good about driving my big truck all while polluting less. I’ve been getting my BioDiesel from Blue Sky Bio Fuels (aka Blue Sky Bio-Fuels) in Oakland. They are very nice folks, and I always leave with a full tank, and additional cubie containers of B100 for later use.

BlueSky Bio-Fuels, as far as I can tell, is the only commercial Biodiesel producer of B99-B100 in the San Francisco Bay area. BlueSky Bio-Fuels offers free used cooking oil collection for restaurants for all of the San Francisco Bay Area, Northern California, the East Bay, the North Bay and the South Bay, as well as Berkeley, Oakland, San Francisco etc. If you are interested in free used cooking oil collection then giving BlueSky BioFuels a call is a good thing for the environment, and you rest assured that the oil will be converted to biodiesel, and taken out of the food chain. Did you know that a lot of used cooking oil gets added to animal feed?

There are also a number of convenient Bay Area Drop Off Locations for Used Cooking Oil that will be recycled into Bio Fuel.

Marshall Fuel Pressure Gauge
My Dodge truck has had a few fuel related issues over the past year and half I’ve owned the truck. Some of these issues were related to a bad mechanical fuel pump that was putting out less and less fuel pressure, and one of the issues was directly related to a bad batch of BioDiesel, and yet another was related to fungus in the fuel that the previous owner had suffered from. To help diagnose these issues, and determine if and when I was having fuel pressure issues, I decided to install a fuel pressure gauge. I also went to my favorite Diesel Forum to ask for help in getting some answers.

In the cab electronic gauges are very expensive, and I couldn’t see dropping over $200 for the occasional diagnosis of fuel pressure problems. Mechanical gauges are much more affordable, but I would not run fuel inside of the cab of my truck. The answer turned out to be installing a mechanical fuel gauge in the engine compartment and taking an occasional gander at the gauge to make sure it wasn’t past time to change out a filter, or to diagnose another problem.

Looked around and found Marshall made just the gauge I was looking for. And it was pretty cheap at under $30, but looks to be of very nice quality, complete with being filled with silicone to protect the gauge against wild swings in pressure. Folks on several diesel forums recommended the gauges, and so I ordered one up. I hooked it up along with a TorkTek snubber at the Injection Pump, where the fuel enters at a banjo. The snubber is supposed to reduce the pulsing of the fuel from the mechanical pump, and to prevent destroying mechanical fuel gauges. From there I attached a grease gun hose that was about 15″ long, and then to a 1/8″ female pipe thread adapter, and then to the gauge. I hung the gauge from a rubber hose using two zip ties, to reduce any vibration from the engine. This seemed to work although the needle of the gauge swung 5-10 psi on either side of the target pressure. The snubber was obviously not snubbing the pressure quite enough.

Left the gauge on the truck and couple months later the gauge failed. Most of the silicone leaked out of the gauge, and of course the swinging of the needle was even more erratic. Returned this gauge to the place I bought it from and they sent me a new one. Installed this gauge, and in a few more months I trashed this one also, only this time the truck blew out the rubber plug at the gauge, and broke the needle. I think the plug went first, and then the needle just beat itself to death from the wildly fluctuating fuel pressure.

Contacted Marshall and they kindly replaced the gauge. In hindsight I think they went above and beyond the call of customer service on this one. The wildly fluctuating fuel pressure of my Cummins was just too much for any mechanical fuel pressure gauge with my set up. And I also wonder about the effect of Biodiesel on the rubber seals of the gauge. The literature makes no mention of using Biodiesel. Biodiesel is hard on some rubber parts and so I think it’s reasonable to think maybe a gauge directly exposed to Biodiesel will eventually fail due to swelling or softening of the rubber.

This time at the recommendation of Rob at TorkTek, I used a 30″ or so piece of marine grade fuel line instead of the shorter grease gun hose. And I used some parts left over from a Turbo Waste Gate project.

It goes together like this:

1. TorkTek Snubber at the fuel injection pump at the banjo.
2. brass hose barb that has a very tiny pinhole size orifice.
3. 30″ of marine grade hose.
4. a second brass hose barb with tiny pinhole size orifice.
5. 1/8 x 1/8 female to female pipe thread adapter
6. Marshall Fuel Gauge

After installing all of this and sealing all threads with Permatex #2 sealer, I started up the truck, and got a non-fluctuating 20psi. Adjusted the TorkTek OverFlow Valve I have on the Injection Pump so I ended up with a non-fluctuating 35psi. Fantastic! No more gauge getting beat to death from fluctuating fuel pressure.

Life is good!
