hi. when a fuel waxed ,how to solve ? in china the fuel have different index number ,for example ,# 0 and # -35,#0 is used in summer,the temperature above 0 'C,# -35 is in the winter about -30'C.,and have # -50.how about in Canada?is there different index number to indicate the wax temperature? what is the # 1D and # 2D fuel waxed temperature ? and when the fuel waxed ,can i add some alcohol to dissolve the wax ? in a textbook ,it said :" Never add gasoline, gasohol, kerosene, or alcohol to diesel fuel. This can cause fire hazards, engine performance problems, and costly fuel system damage." if don't add alcohol ,how to solve this problem?

i know John will answer me ,so pre thank John. : ) hehe

We don't deal with waxing much here in my part of the world, because it doesn't get very cold at all here, but I have heard that fleets in colder parts of the states use diesel fuel additives to prevent waxing and gelling in cold weather. Here is a link I found for some additive that they sell :


I don't know what particular fuel index they use here in the states, but my cousin works at the Tesoro refinery and says they do produce a "winter" and a "Summer" blend of fuel to deal with the different temperatures.

thank you so much Christopher,additive is a good way.

In Canada, almost every fuel distributed pumps winter fuel form late sept to early may depending on were in Canada you are. There are still guys adding anti gel stuff to there tanks although unless your using poor grade fuel or summer fuel in the dead of winter I can see no benifit. The fuels are of such good quality now gelling i should not be an issue.

Hey Xiaobo. Like the previous post mentions, the refineries are switching the grades for us, so we don't have a lot of those waxing/ gelling issues. However, when it does happen, like when you come across a machine that's been sitting for awhile, there is one product we come across that works wonders. It's called 'Diesel 911' by Power Service Diesel Additives. It won't prevent gelling but will liquify already gelled fuel.

One thing that's saved a lot of headaches over the cold months is to drain the water from the tank. I'd drain off 5 gallons from every tank then we'd have lots of fuel on hand to start our bonfire over the winter. Problem solved.

Thanks for the recommendation mrbigwrench, I brought up the issue of gelling with my shop manager last night, and he said it's possible with some of our equipment now because we picked up longer runs into Oklahoma and Texas. I will bring up the 'Diesel 911' to him tonight.

Thank you Ron and mrbigwrench。

Glad to be able to pass it on. Don't forget to keep the product warm. Adding cold additive to cold fuel won't work.

It's surprising to read you need the stuff for Texas. It got a little cold down there this year but never THAT cold! Whatever works for ya!

Each of our units carry the 911 on board just in case. First sign of gelling the drivers know to dump it in, works great as long as engine is running to pull it through the system. I have suppliers telling us that they are seeing some of the worse issues this year because of the fuel grades that are now out there. The suppliers can add a certain amount of bio fuels with out having to disclose it to the consumers. I was surprised to hear that, has any one else heard that?

It's been law in Canada for awhile now that regular gas must be diluted with 10% ethanol. I believe it's the same for diesel now too.

So the biofuel was supposed to be the greatest thing for the environment since electric cars came into being, but what about all the issues around biofuel? Around 2008/09, there was panic when we realized the crops needed to produce biofuel was taking food away from the starving masses around the world.

One point almost as critical as that was the fact there is a large drop in horsepower the engine produces when fed biofuel. So if it's going to take more fuel (therefore more emissions) to do the same job, where is the benefit to society?

There is always a give and take isn't there? The world needs to be fed and protected from global warming at the same time It's going to take a lot of research and testing to design the perfect emission free vehicle that does not take anything away from anyone or anything. Our Hybrid electric bus from 2008 is back to a regular diesel engine because the hybrid manufacturer couldn't find a battery pack that worked.

The puppets that are our government leaders are falling all over themselves to be seen as 'eco-friendly' and rushing legislation through before the technology is ready for market.

Speaking of which, I wonder how the fuel cell busses are doing? They make a big deal when the municipality buys them but we haven't heard much about it. I heard most of them are in Vancouver, but if anyone can update us on it, it would be appreciated, thanks.
