HEY GUYS

I'VE GOT ABOUT 1400 MILES ON THE V-10 NOW AND I AM AVERAGING A SOLID 13MPG RUNNING BACK ROADS AROUND RURAL MISSOURI HERE. 14 ON THE INTERSTATE @75MPH.

I'M LOOKING FOR INPUT ON PROPER BREAK-IN PROCEDURES THAT EVERYONE HAS USED. I'VE HEARD BABY THEM FOR 5000 OR BREAK EM IN LIKE YOUR GOING TO USE EM. I'M PLANNING ON TAKING THE CAMPER (8500#s) UP NORTH FOR A LITTLE HUNTING TRIP AND ALSO JUST TO SEE WHAT SHE'LL DO.

 

Consider it broke-in.
You can expect some fuel mileage and horsepower increases the next 2 or 3 thousand miles.

I changed my oil at 1000 mi.just for good measure.

 

Big Blocks don't break-in 25,000 to 30,000 miles.

At time they stop using oil.

There is a big change 30,000miles m/p/g up 2 or 3.

 

Is the V-10 really considered a big block?

 

Most of your break in happened the first few hundred miles, though things can continue to seat up to around 10K miles from what I have seen. At 1500 I would drive it like you intend to drive it. Keeping the RPMs too low all the time can hurt your ability to get good high end hp later.
