What Grade of Gasoline do you use

I'll second that. Kerosene does not have enough lubrication for the injection pumps. Maybe on some older diesels, like the Cummings B5.9 used in the early Dodge trucks (90-98), but you will risk voiding the warranty if it is discovered you are using anything but what the Owner's manual recommends. Kerosene is inbetween Diesel and Gasoline in the refining process. Some Diesels will run great on JP4 or AV1 (Jet fuel, basically Diesel with winterizing agents for the cold air at altitude).

In addition, Kerosene is considered Off-Road only and the fines can be stiff if it is found in your vehicle....

i didnt mean kero in personel trk .it is for my hot unit .

[steve r]

i thought this thread was for gas for pressurewasher and hot units

Sorry, I misunderstood.

Sorry Steve, You are right. I am easily sidetracked .

Here in Central Fl, Kerosene is about impossible to find. #2 Diesel is about the only thing available. Some Mom & Pops carry off-road diesel, which is what I run in my tractor and my torpedo heater for my shop. A hot water unit is not in my budget as of now, but maybe in the next few months when I get rolling.

The thread title started off regarding pressure washers, but vehicles were added in by various posters. The point is, we are discussing engines right?

We use diesel in the Hydrotek's burners, just have not tried Kerosene. We use diesel in the Sprinter for obvious reasons. Our other trucks are gas. Our engines on the Hydrotek's, like the gas engines in two of the trucks, get premium fuel.

Hope this is clearer.

Beth, don't forget to add a cap full of soot remover with every fill-up of diesel. It'll keep that Hydrotek running longer (actually it's not a hydrotek but rather a burner thing).

Higher octane in fuel raises it's burning temperature and requires higher compression pressure to burn efficiently. Using higher octane in a normal engine results in incomplete combustion, less power, carbon fouling of the cylinder and, most important, wasted money.

To accomodate the higher octane, it is necessary to adjust the carburetor settings to run less lean and add more air to the mix to acheive better combustion if you are having this problem. The factory preset on Honda, Vanguard and Kohler engines will accomodate premium gas...I own each.

Octane rating is a number relating to the 'anti knock' properties in fuel that is added to it. It is what helps the engine to run smoother because of the oily paraffin hydrocarbons that are added to normal gas (heptane) to produce the anti knock quality we can choose at the pump.

Fuel additives can provide some benefit but I have found in small engines they are unnecessary because of the high heat generated after running a few minutes. These engines do not have the same type of cooling system that vehicles do and become very hot from induction allowing the fuel to burn quite well and without resulting in carbon deposits. These are formed when the engine is only run for short periods of time and are not allowed to reach operating temperature and cannot sufficiently burn off the excess hydrocarbons in the fuel.

This could become a good maintenance discusion in another thread.

I used kerosine in my burner for awhile besause I was told that it burned hotter than diesel,I went back to diesel after I was told by technician that the fuel pump would not last as long with kero because of the less amount of lubricants. As far as gas goes,the owners manuel for my truck says if an enginr is rated for 87 octane it will not perform any better with prem. fuel. If you want to clean your engine valves,plugs etc. just burn a tank of Amoco premium from time to time. Amoco premium is different than other prem fuels because of less additives, if you'll notice it is almost clear in color. This is just my 2 cents

Your tech was right. I ran about 30 gallons of K-1 in my burner because it was cheaper and sure nuff it burned up my fuel pump and fuel solinod. Now I only run Dyed diesel.

I figured id clear a few things up.....will high octain ruin my honda motor? No will it give me inproved performance? no will it help to run cleaner? no

MOst honda motors including some of the major cleaner motors gx610 gx620 gx 670 run @ 8.3:1 compression ratio, high octain fuel requires a longer burn tme as said earlier, and is actually LESS explosive than lower octain fuels. This fuel burns through a longer period of time throughout the stroke. Having these characteristics, higher octain fuel is recommended for compression ratios 9.5:1 or higher or forced induction applications where both air and fuel are pushed into the cylinders creating higher compression. By using a higher octain fuel in a lower compression motor will result in unburned fuel, adjusting the carb jet sizes for more fuel or air mixture will just lean or richen this condition not cuase for a complete burn. So, use whichever fuel you desire, they all will work. Higher octain fuel wont give you any gains nor will it hender so basically its just your extra 10-20 cents a gallon.

took the words right out of my mouth sfla ...
Octane is an alkane with the chemical formula C8H18. It has 18 isomers.
One of the isomers, 2,2,4-trimethylpentane or isooctane, is of major importance, as it has been selected as the 100 point on the octane rating scale, with n-heptane as the zero point. Octane ratings are ratings used to represent the anti-knock performance of petroleum-based fuels (octane is less likely to prematurely combust under pressure than heptane), given as the percentage of 2,2,4-trimethylpentane in an 2,2,4-trimethylpentane / n-heptane mixture that would have the same performance. It is an important constituent of gasoline.

Regular in everything. I read an article that basically disproves the whole Premium thing except for very high performance engines. Since I don't race Formula One I will stick with regular.

[doublejager2000]

the only thing a high octane means is when a fuel will Resist <<sorry im not a speller. Igniting do to the pressure of a piston and the heat of the friction preventing" knock". preignition is knock an makes a pinging sound as you bring your RPMS up as the fule explodes b4 it is wanted . this wastes fules unless the engine is made for it .yes the fuel burns hotter but you have to have the right engine for it to. i grew up building motors go to any shop and ask 8.5 or lower compression only needs 87 octane. every air cooled i have ever seen is much less than 8.5 mostly 7.6..... ......" if it cost more does not mean its better"
