Break-in To Avoid BreakdownsProper nitro engine break-in is critical for long-lasting performance of your RC. Every new nitro engine should undergo a break-in procedure. Breaking in a nitro engine takes anywhere from one to two hours and about 3-5 tanks of nitro fuel. If you do the nitro engine break-in properly, the up-keep on your RC vehicle is less costly than if the procedure is done hastily and incorrectly. Be patient. Even after the initial break-in, it may take running through an additional 5 or more tanks of fuel before the engine reaches its full operating potential.
Each nitro engine manufacturer may offer specific break-in procedures, but this general nitro engine break-in procedure works well if you don't have other instructions.
