Distilled water that has been ‘DEIONIZED” is extremely active electrically and should NEVER be used in your 

boiler. Often water Will be OZONATED to kill bacteria. Water that has been ozonated is acceptable as long as it 

has also been steam distilled.

* We recommend only the use of STEAM DISTILLEO water in your boiler *

Oil

Since the beginning of the steam age there has been a heated discussion of which oils are best for cylinder lubri-

cation. The development in recent years of a plethora of synthetic oils has only exacerbated this discussion. All 

the major oil companies now produce innumerable synthetics; yet they all still recommend similar, non-synthetic, 

oil and tallow blends for the use in saturated steam cylinders. Although these may carry individualized brand 

names, they are all a compounded ISO 460 heavy oil for use in steam cylinder environments. They have all been 

developed to resist being washed off the metallic surfaces by the action of water and hot steam, and all are de-

signed to be carried to the necessary lubrication points by being entrained in the stream of steam. The oil compa-

nies also occasionally reference these oils as “ AGAMA 7 Compounded” oils, and they also come in weights other 

than ISO ratings of 460.

Oil that meets this specific criteria is available from your Accucraft Dealer and from Sulphur Springs Steam Mod

-

els, as well as from the bulk distributors of the various oil companies. What you need to ask for is “ISO 460 Steam 

Cylinder Oil, AGAMA NO.7 Compounded.” Esso names their brand of oil” CYLESSTIC ,” Conoco calls theirs” Inca 

,” Chevron references theirs as” Cylinder Oils W ,” Mobil uses the name” 600 W Super Cylinder Oil,” and Phillips 

calls their oil” Hector.” Also available is “Green Velvet Steam Cylinder Oil.” We have not tried this oil, and have no 

opinion as to its suitability, but it is being used by various “ride on”, 7.5 inch gauge builders. It can be purchased 

from William L. Petitjean, P.E., Inc. doing business as Steam Engine Lubrication Specialties. Their address is P.O. 

Box 1118, Fall City, Washington 98024, telephone 425  222-6781.

**** We recommend only the use of the ISO 460 oils listed above ****

Excess oil beyond that necessary to lubricate the valves and cylinders is detrimental to the locomotive.

Unlike a butane fired boiler, your K-28 does not have any holes or drain in the bottom of the smoke box. This 

means that excess oil delivery to the cylinders will become mixed with cinder and ash to form a sludge in the 

smoke box, besides forming this sludge, oil soaked cinder and ash can be carried out the stack to be deposited 

as an abrasive on the running gear.

To ensure proper lubrication your K-28 conversion is fitted with an adjustable lubricator and oil piping that is sepa

-

rate from the main steam line. This allows the oil flow to be regulated to optimize lubrication while reducing excess 

oil residue in the smoke box and oil splatter on the exterior of the locomotive. The use of a proper steam cylinder 

oil as listed above, one that has high adhesion and resists being washed away, means a proper adjustment of the 

lubricator can be made. Adequate lubrication of your valves and cylinders results from an oil flow rate of between 

1 and 1 1/2 cc of oil per hour. Oil flows in excess of this are unnecessary, wasteful and can contribute to cleanup 

problems and excess wear and tear on the running gear. Proper adjustment of your lubricator will be covered in 

detail further on in these instructions.
