just use a normal 10w-30 oil right, then after 500 miles or so change and then run what ever i want? just dont break in with a good full synthetic right.
thanks- Brian

Try and get a single weight break in oil Valvoline do one as do many of the other companies.

In 5 Qts of your 10-30 you would have 4 Qts of Oil and 1 Qt of vicosity index improver which isn't actually Oil not to mention most Oils these days are Friction Moddified a big no no for a new Build.

Yes but VERY important to get one that has minimal additives or friction moddifiers I can't stress this enough as the Block is quite hard and if you use FM's it may never seat the rings.

Very welcome Brian!

I try to post my reasoning why and not just expect people to blindly follow anything I say :)
(been wrong in the past and I'm sure I will be again in the future)

Ian is human you know...

But yes a straight 30 weight would be great for break in.

Also, do not let your Rpms go below 1500 for the first half hour of the engines life.

i think i read somewhere on here that you need to drive it fairly hard for that time to force the rings to seat properly before the they wear the hone off the cylinder then they wont ever seat right... this may be wrong but i vaguely remember something like this...

The factory manual says between 2000 and 4000 never driving at one constant RPM for a long period of time.

Yeah, you're talking about this: http://www.mototuneusa.com/break_in_secrets.htm

That makes sense MDC, but what warming up to idle? Should you just start it and immediately take it to 1500 and just vary above that mark? Would make for abit of a tricky break in for city streets :icon_surp
