OIL
Fuji-Imvac engines has developed a special oil, Super Lube Oil (FJIP9910 – 250cc),
to work with their engines. This oil is of extremely high quality and it has exceptional
lubricating properties. This oil can be mixed with gasoline at much higher ratios than
other engine oils which allows the engine to develop more horsepower and last longer.
It is recommended that you use Fuji-Imvac Engine oil with all your Fuji-Imvac engines.
Break-in procedures are slightly different than those when using standard oils. Please
refer to the table below for oil contents. Fuji-Imvac Oil is available from your Fuji-Imvac
distributor or hobby shop.
·
Break-in (Stage 1): 1 gallon of gasoline with 50:1 (2%) oil content.
·
Break-in (Stage 2): 1 gallon of gasoline with 100:1 (1%) oil content.
·
Normal running: In un-cowled or well-cooled installations 150:1 (0.65%) oil
content.
·
In-cowled or not-so-good cooling installations 100:1 (1%) oil content.
·
Do not try to use these engine oil ratios with any other brand of oil other than
the Fuji-Imvac oil.
·
Do not use the Fuji-Imvac oil with any other brand of engines.
·
If you have been running the engine on other oil and wish to switch to Fuji-Imvac
oil, follow the break-in procedure for Fuji-Imvac oil.
If Fuji-Imvac oil is not available, or if you prefer to use a different brand of oil, use
the standard fuel/oil ratios as shown below. Never experiment with cheap oil or
with obscure brand names. Be certain to select only high-quality oil that is
intended for use in gasoline R/C model airplane engines.
