What is algae biodiesel?
Propel's B20 is made of 20% SoladieselBD (an algae-derived biodiesel made by Solazyme) and 80% petroleum diesel. Domestically produced from micro algae that efficiently convert sugars into renewable oil, SoladieselBD is a clean-burning, precision quality fuel that is compatible with all diesel vehicles.

For more information about SoladieselBD, please visit Solazyme's Fuels page.

Who can use algae biodiesel?
Like all of Propel's high quality biodiesel blends, Biodiesel B20 featuring SoladieselBD is compatible with all existing diesel engines. SoladieselBD meets or exceeds ASTM quality specifications and has shown performance enhancements including cold temperature operating performance. And of course, Propel's algae biodiesel is backed by our Performance Guarantee.

Learn more about running Biodiesel B20 by visiting our Resources page.

What are the emissions benefits?
Testing undertaken by the National Renewable Energy Laboratory (NREL) shows that, in a 20% blend, SoladieselBD significantly outperforms ultra-low sulfur diesel in total hydrocarbons (THC), carbon monoxide (CO) and particulate matter tailpipe emissions. This includes an approximate 30% reduction in particulates, a 20% reduction in CO and an approximate 10% reduction in THC.

Recently, automatic transmissions have been dropping like flies around our shop.  We have had to rebuild over 10 transmission in the last two months. That is more transmission work then we have done in the previous 5 years combined!  These are not just the 99-2003 ALH 4 speed auto trannys that notorious for failing - we have had to rebuilt the BRM Dual mass tranny, the BEW 5 speed tiptronic,  and two BHW Passat 5 speed tiptronic transmission. One of the Passat tdi wagons that had a transmission failure only had 66,000 miles on it!  

VW tdi owners have been reading on the various forums that these transmissions need to be serviced.  VW has stated that these automatic transmissions do not have a recommended service interval and that the ATF fluid is lifetime.  Tons of VW tdi gearheads particularly on the tdiclub forum are saying that the failures of transmission may be caused by the lack of transmission servicing.  They are recommending transmission fluid changes every 50,000 miles.  I am not going to agree or disagree with them, only offer a word of caution that these services might be having a counterproductive effect.

The Passat tdi that only had 66,000 miles on it with a failed transmission was LOW on fluid when we checked it out, yet there were no fluid leaks on any kind!  My guess is that at some point in the cars life, the previous owner read about the transmission service on the tdi forums and ran to a shop to get this done. Unfortunately, the shop did not follow the rather complicated procedures in refilling the transmission and shorted it a half quart. It probably was driven thousands of miles on low fluid then sold to my unfortunate client who had the transmission fail on him the day after he bought the car!  

So the moral of my long winded story is that IF you are going to get your VW tdi automatic transmission serviced, PLEASE PLEASE take it to a VW dealer or shop who knows exactly how to refill it perfectly.  As for me, my 2004 Jetta tdi wagon is coming up to 150,000 miles - still with original transmission fluid and still going strong.  I might just leave well enough alone.


So you have put a diesel performance exhaust, diesel performance chip and performance intake on your rig, if you had put those diesel performance products on your truck a few years ago you would have been considered a diesel performance connoisseur or someone who was into extreme diesel performance.

The fact of the matter is that in the past few years the diesel performance industry has grown by leaps and bounds and what were considered to be extreme diesel performance modifications back then won't even let you keep up with the big boys nowadays.

Once you have gone beyond the standard diesel performance mods and are ready for extreme diesel performance there are some common diesel performance products that you should be aware of. If extreme diesel performance is your goal, then the most common diesel performance parts to put on your truck after the typical chip, intake and exhaust are larger injectors, a larger turbo and possibly an upgraded injection pump or lift pump.

Larger Injectors
Part of the equation for more horsepower is more fuel. By pouring more fuel into the cylinder you will be able to increase horsepower and torque, the thing that most people don't know about larger injectors is that they also increase diesel fuel mileage. Most of the misunderstanding comes from the terminology itself, of course if people hear "larger injectors" they just naturally think that the holes themselves are going to be bigger when in all actuality injectors get larger in a couple of ways, the size of the holes in the injectors and the number of holes in the injectors. Increasing the size of the holes is usually accomplished in a couple of different ways, first is by laser cutting and second is a process known as extrude honing. There has been some debate as to which method is better but our experience has shown that the extrude hone process allows for smoother holes in the injectors themselves allowing for an increase in diesel fuel mileage. The second way that injectors get "larger" is by increasing the number of holes in the injector nozzles, by increasing the number of holes in the injector nozzles you get a finer mist which allows for a better atomization. The increased diesel fuel mileage is with conservative driving of course.

Pump Upgrades
If you are planning on pumping more fuel in with larger injectors you need to make sure your pump is up to the task. The amount of modification your pump will need as well as the options you have available to you will rely mainly on the year, make and model of your vehicle. For those vehicles that have a rotary style pump such as the Pre-1994 Dodge Cummins, 6.2L and 6.5L Chevy Diesels and even the 99-02 Dodge Cummins VP44 pumps you will be a bit more limited as to the modifications that you will be able to make to your pumps.

The main reason mods are limited on these style pumps is because of the fact that they are lubricated by the fuel, so if you fail to run additive through each tank you may sieze your pump regardless of which mods you have made, with that said, Industrial Injection has made some crazy modifications to the VP44 pump so look for the HOT ROD and DRAGON FLOW versions of that pump. If you are fortunate enough to drive a 94-98 Dodge Cummins with the Bosch Inline p7100 pump then there are a plethera of modifications that you can do, one of the easiest of those being the installation of the Dynomite Diesel Fuel plate. If you have a newer common rail pump your task is all about keeping your rail pressure up so you can do that with a modified pump or by running dual feeder pumps. Now modding your injection pump is only half the battle, you still have to make sure that your lift pump can keep up with the demand as well and there is where systems like the FASS and AirDog come in handy.

Larger Turbo
Once you have plenty of fuel running to through your system it's time to use all that extra exhaust that is being created to turn a bigger turbo. When it comes to upgrading your turbo you have several options including, ball bearing, stainless steel, waste gated or non waste gated, variable vein or not. Picking out just the right turbo charger comes down to your application and personal preference so we won't go into great detail on that topic but do plenty of searching or come to our site for more information. The big names you will see throughout the industry include, Industrial Injection, HTT, Turbonetics, ATS and many more.

2009 VW TDI Performance Upgrades are finally here! If you've been waiting patiently for the chance to modify your 2009 TDI, your wait is over.

True Volkswagen TDI enthusiasts have something to cheer about as new Performance and Upgrade product releases are here for the 2009 VW JETTA 2.0L TDI Sedan and Wagon. After Volkswagen's decision not to manufacture 2007 and 2008 VW TDI'S, many TDI enthusiasts have pounced on the chance to buy a factory fresh 2009 TDI Jetta. With no TDI vehicles coming off the VW assembly line for a few years, manufacturers of VW TDI upgrades had to turn their attention to other product lines. Now, however, with the popularity of Volkswagen's new 2009 TDI Jetta's, upgrade and modification companies have taken note and are again giving car owners the types of Performance products they crave - products that until only recently had been reserved for older model VW TDI'S.

Performance Cold Air Intake Systems and Rapid Power Module's, or "Chips" as they are often called, are two of the easiest, least expensive, and most effective upgrades you can make to your 2009 TDI Jetta. Diesel engines want cold air to breathe and properly atomized fuel to burn, and an upgraded intake and module will give your TDI just what it needs. If you are interested in maximizing the full potential of your VW TDI, read on.

To give your Turbo Diesel more cold air, a high-quality choice comes from Advanced Flow Engineering, or AFE Power as they are commonly known. AFE has recently released a Performance Air Intake System for the 2009 Jetta TDI 2.0L with an impressive list of benefits and performance data. The system is 100% bolt-on, mounts to the lower airbox housing, and no drilling or cutting is required. After a simple 15-30 minute installation, you can expect air flow to increase 56% over stock. Horsepower gains average +10 at 3150 RPM, and expect Torque to increase by 23 lbs. at 3050 RPM. The system comes with a high efficiency, low restriction air filter in your choice of either a Pro Dry S or a Pro 5R. Most people choose the Pro Dry S for ease of use with filter cleaning being a simple wash and air dry.

Performance modules improve TDI fuel economy and provide extra horsepower at the same time by improving the efficiency of the vehicle fuel injection system. Performance market manufacturer and TDI stalwart Bully Dog now markets a "Rapid Power Performance Module" for the 2009 VW TDI Jetta which effectively improves fuel economy and horsepower. This module is a simple inline, between wiring harness, plug-in chip designed for safe and long lasting use. It is adjustable on-the-fly, allowing you to choose between three power levels; Stock, +10% and +15% horsepower via a simple toggle switch that can be left in the engine bay or installed within the interior of the vehicle for easy access. The total horsepower increase from this module on the highest setting according to Bully Dog's Dyno testing is +25HP and a torque increase of 30 ft-lbs. If you can keep your foot of the gas pedal you should even see some impressive fuel economy gains on a car that already gets remarkable mileage.

Combine the Performance Cold Air Intake System with the Rapid Power Module and you'll see tremendous gains in horsepower, torque and economy; perhaps most importantly, though, will be the increased fun you'll have driving your modified 2009 VW Jetta TDI!

A 2009 VW TDI Performance Intake together with the 2009 VW TDI Performance Chip will make both you and your 2009 Jetta very happy.
