As stated, the breakin should be done ai diff. rpms if possible, but break it in hard not soft. Also do NOT use synthetics while breaking in, they will not let the motor break in because of its extra lubricity abilities.

 

I know I waited until after the break in to use the ams.

 

It is my personal preference and I use synthetic oil stariting on the 1st oil change. I don't believe in the "waiting for rings to seat" - it is a myth to me. What I am saying is that "waiting" makes a sense but it is not proven in my experience. I've been using synthetic oil on many of my new cars and bikes since day 1 for last 25 years and I've never had any problems. My old '86 Toyota Cressida ran good for 300,000 miles without burning oil or smoking and I used the synthetic oil right out of factory from day 1. Then I sold it for $2500 about 20 years later. The engine still ran like when new. Some expensive cars already come with syn oil from the factory like vettes and all MBs. I just use syn oil as soon as I can and everywhere I can including my B&S lawn mower. I use Mobil 1 because of their long history and known reputation.

 

i am on my second brute force and it doesnt take abuse to break the tie rod it takes miles both of my brutes broke around 1100 mi and what happens is all of a sudden the tierod end just comes apart

 

Too much air on the track blew out the front shocks then bent the floorboard mounts. The new shocks $200.00, fixing the floorboards a little adjutsment whith a sledge hammer, the look on the kids face when he couldn't outrun a ute with his 700 Raptor priceless!!!
