W85 is a type of diesel fuel that is made up of 85% waste motor oil (WMO) and 15% gasoline. It is a cheaper alternative to pump diesel and is known to work well in Ford and Dodge diesel trucks. W85 has a higher octane rating than regular gasoline, which means it can be used in higher-compression engines that produce more power. However, it can cause issues with fuel pumps and injectors, leading to smoking problems.

What You'll Learn
W85 is an 85/15 blend of diesel and gas
W85 users have reported issues with stock lift pumps not being able to pull W85 through their fuel filters. To address this, it is recommended to use a slow positive displacement pump, such as the Walbro FRB-5. Additionally, modifying the fuel system with larger lines from the tanks to the pump can improve performance.
W85 can help solve smoking problems in diesel engines caused by worn injectors. By using W85, users have reported reduced white smoke and improved mid-range torque.
W85 is a cost-effective alternative to regular diesel fuel, with some users reporting savings of over $600 per month. It is a popular choice for those interested in alternative fuels and home-brewed fuel blends.

W85 is a high-performance, non-gelling fuel
W85 is particularly suitable for Ford idi and Dodge Cummins trucks, as well as Ford idi pickup trucks. These vehicles have swirl prechamber designs, which prevent clogging when using W85. The swirl prechamber design also suits WMO well. W85 has also been used in a 1990 Toyota Corolla 1C diesel engine, a Toyota Corona Diesel 2C, and a Mitsubishi Pajero Diesel 4D56-T.
W85 users have reported issues with fuel pumps, as the stock lift pump may not work with W85. A suggested solution is to use a slow positive displacement pump, such as the Walbro FRB-5, which is a reciprocating piston pump. Additionally, modifying the truck to have a gravity-fed pump can improve performance.
W85 users have also encountered smoking issues, which can be caused by worn injectors. Replacing the injectors with new or near-new ones can help resolve this problem. Overall, W85 is a viable alternative fuel option for certain vehicles, offering high performance and cost savings.

W85 is a home brew that doesn't need to be heated
W85 is a popular choice for those seeking an alternative to regular diesel fuel. It is suitable for Ford IDI and Dodge Cummins trucks, as well as some older models such as the 1983 Chevy 6.2L diesel. It is also possible to run W85 in a 1990 Toyota Corolla 1C diesel engine, although this may require some modifications.
One advantage of W85 is its ability to work in cold temperatures without the need for pre-heating. This is due to the blend's high ethanol content, which has a higher octane rating than regular gasoline. The higher octane rating allows W85 to be used in higher-compression engines, resulting in increased power and performance.
However, there are some challenges associated with using W85. One issue is the need for a specific type of fuel pump, as the standard stock lift pump may not be sufficient. Additionally, carbon build-up can be a problem, especially with worn injectors. It is recommended to use near-new injectors to avoid this issue.
Overall, W85 is a viable alternative fuel option for those seeking to save money and increase performance, particularly in older vehicles. Its ability to work without heating makes it a convenient choice, although some modifications and mechanical knowledge may be required for optimal use.

W85 is a fuel blend that can exacerbate pre-existing mechanical problems
W85 is a fuel blend consisting of 85% waste motor oil (WMO) and 15% gasoline. It is a cheaper alternative to diesel fuel, and can be used in some diesel engines, such as Ford IDI and Dodge Cummins trucks, as well as certain Toyota and Mercedes models.
While W85 can be a viable option for some vehicles, it is important to note that it may not be suitable for all engines. Running fuel blends like W85 in old vehicles that are not properly serviced can exacerbate pre-existing mechanical problems. This is because W85, being a blend of waste motor oil and gasoline, has different properties than regular diesel fuel.
One issue that has been reported with the use of W85 is the potential for carbon build-up in the engine, particularly in the injector heat shields and pre-combustion chambers. This can lead to reduced engine performance and increased smoke emissions. In one case, a user reported that their Toyota Corona Diesel 2C had a white smoke haze while running on W85, which was attributed to worn injectors.
Another consideration when using W85 is the type of fuel pump required. Some users have reported that their stock lift pumps were unable to pull W85 through the fuel system, and they had to switch to a different type of pump, such as a gravity-fed pump or a slow positive displacement pump.
Additionally, W85 may not be suitable for use in cold climates. Ethanol-blended fuels like W85 can be difficult to start in cold temperatures due to their lower heating value. This is why, in some regions, ethanol fuel is blended with gasoline or pre-heated to facilitate engine starting.
In summary, while W85 can be a cost-effective alternative to diesel fuel for certain vehicles, it is important to be aware of its potential drawbacks. It may exacerbate pre-existing mechanical issues, particularly in older vehicles that are not well-maintained. Additionally, it can contribute to carbon build-up and may require modifications to the fuel pump and fuel system. Finally, its suitability for cold climates is limited due to its lower heating value. As such, it is important for vehicle owners to carefully consider the benefits and drawbacks of using W85 before making the switch from diesel fuel.

W85 is not compatible with all fuel pumps
W85 is a blend of 85% waste motor oil (WMO) and 15% regular diesel fuel (D2) or gasoline. It is a cheaper alternative to diesel fuel and can be used in some diesel engines, such as Ford and Dodge Cummins trucks, and certain Mercedes Benz and Toyota Corolla models. However, it is important to note that W85 is not compatible with all fuel pumps.
Some users have reported issues with their fuel pumps after switching to W85. In particular, the stock lift pump, which works fine with D2, may not be able to pull W85 through the micron filter on the WMO aux tank. This can cause the pump to stop working altogether. This issue does not seem to be widespread, as some users have reported no problems with their fuel pumps after several thousand miles of driving on W85.
It is recommended to use a slow positive displacement pump for W85. A Walbro FRB-5 reciprocating piston pump is suggested as it only cycles when fuel is demanded, which can extend filter life. Additionally, modifying the truck to have a gravity-fed pump can improve the performance of the pump. It is important to follow the directions that come with the pump, as some pumps, like the HOLLEY pump, specifically state that they need to be gravity-fed.
It is worth noting that running W85 in older vehicles with pre-existing mechanical problems may exacerbate these issues. Therefore, it is important to properly service and maintain vehicles before considering alternative fuels like W85. Additionally, W85 may not be suitable for use in very cold climates, as it may be difficult to start engines due to the lower heating value of ethanol.
