Best cetane booster???

I just wiki-ed cetane and octane. Always good to learn something.

cetane is a rating used for lighter fuels so my for 30W question the answer is a different rating scale would be used, one for residual fuels. I know 30W has plenty of BTUs compared to no2 fuel oil just by how long a puddle of each in the yard will burn (my weed eradication program at home), the motor oil will burn and burn long after the diesel went out.

Anyways "The higher the cetane number, the easier the fuel ignites; the higher the octane number, the more resistant the fuel is to ignition."

Cetane rating doesn't affect BTU rating, all it means is how soon the mixture starts combusting, which today's electronic diesels can alter the injection timing to compensate for. A low cetane fuel might prompt the ECM to advance the fuel injection to keep cylinder pressure steady or high cetane fuel might be cause to ###### timing. Therefore adding expensive adulterants to your fuel in hopes of tinkering with the cetane rating likely has no performance effect on a modern computer engine.

I would love to get full tanks of the 52+ Cetane diesel fuel they use in Europe. It would probably be alot more power along with alot better fuel mileage. That is one reason they can get 10+ mpg with a cab over truck......well that along with a governed maximum speed of around 52 mph kind of helps out too.

Let me add that I am a believer in the Walmart 2 cycle oil after trying all the others. Hard to beat $12 per gallon compared to Lucas costing around $30 per gallon.

 

2 cycle oil will not get your cetane up. Cetane boost and any oil are two different things...

 

Bio does more for increasing lubricity than any of the off the shelf products ever could. A simple 2-5% bio blend will raise lubricity to pre-LSD levels for no increase in pump price. That's what I said... pre-LSD levels, not just pre-ULSD levels. Also bio does increase the cetane a little, but not that big of a change. maybe a couple of points. I will concede, bio has its own set of problems, but that is another issue. Now it is a good idea to use some form of additive that has a detergent property to keep things cleaned up. And, of course, handle water and gelling issues. But if lubricity is your main goal, it is a waste of money.

 

Doesn't bio act as its own detergent?

i know that soy bio diesel is a sponsor of the NTPA and a few other tractor pulling groups, most of which have limits on cetane, I have heard that a few times this year that the bio has tested higher than what is allowed straight out of the pump. Seems to me that it is quite a bit higher than straight #2.

 

The only problem I see with bio-diesel is the quality is not the same across the country. I will not put bio-diesel in my truck in the Southern USA and in fact the TA in Duncan, SC quit selling it due to so many complaints. I would not be afraid to use the bio-diesel in the Midwestern states that have had it around alot longer, but it is still not my first choice. Bought some at TA in Hudson, WI last week that did not run as good and fuel mileage may have been a little worse with it in my truck.

 

with bio from the loves in n. AL. I have to change my fuel filt every 200- 2000 miles, otherwise 25,000 is common before needing changing, davco sys.

 

Yeah, bio does have a cleaning quality about it for the fuel system, but I am not so sure about the injectors themselves. And true, the quality varies around the country. I run primarily in the Upper Midwest, so it is a little more consistent. I have only gotten a bad batch at the Sapp Bros in Peru, IL. But I have fueled there a few times before and since with no issues. I guess until everyone gets on the same sheet of music, we will have this "hit or miss" situation with bio. And the EPA has just come out and raised the threshold on how much biodiesel they want produced and out at the pumps. This probably would go a lot smoother, like most things, if the EPA would jump the gun on some of this stuff. They remind me of a little kid.... they want what they want, and they want it right now, and the consequences don't mean a thing.
