Hello fellow hobbiests.
I understand it takes 5 tanks of fuel for the break in period. However IM a little fuzzy on what is the best way to opperate your car during those tanks. I think the first tank you just idle through? Not sure if I should slowly increase speeds each tank, or what.

Personally, I follow the advise of the Fuelman.Β* He's blended fuel for many years and broken inΒ*more engines than any 8 people on this forum.Β*Β*
Preheat engine to at leastΒ*200 degrees.
Run engine at least 200 degrees.Β* Wrap the engine head to keep the temp up.
Do not idle tanks of fuel through engine.Β* Run the vehicle on the ground.
Total break inΒ*usually takesΒ*about a gallon + or -Β*
Running slightly rich is OK, but low temps will stress the rod (tight pinch)Β*and cause premature wear and failure of the rod.
Set piston to BDC during cool down.
''A good proper ABC type engine break in does not run too lean nor too rich. It involves loading the engine, freewheeling does the engine no appreciable good. Parking the needle at some magical temp displayed on a LED screen is 99% useless. Everything assumes we have some common sense so runaways from servo arms disconnected, bad clutch springs and so on should not be argument pursuaders for or against anything.
Guys, stop trying to re-invent the wheel. What is outlined on the break-in link in one of my previous posts is for the most part what the company that invented the ABC metalurgly / technology back in the mid 1960's came up with to achieve maximum power with longevity. Very very little has changed in the metalurgy and fits of the ABC pistons/ sleeves since then.''
