black oil already?

[Kwazrollinz28]

Isn't royal purple synthetic?

yep, but the oil i took out was cheap shit just for starting the motor for 200miles, It was advance auto brand for like 2 dollars a quart.

Eh, I thought you're suppose to wait like 1500-3000 miles before using synthetic?

[98blackbeauty]

I always heard you should change oil 200 then 500-600 miles then 1500 miles before going to synthetic. some people recomend 3000 before synthetic.

Eh i suppose, Doesn't matter to me.
not really a rebuild its just a new pump and cam.

Good point. It's funny when you think about the differences between hobby cars and the way it's done at the factory.

I was under the impression that all engines are broken in (to a point) somewhere along the assembly line.

Negative...I got to take a tour of the 3800 plant in Buick City some years ago, and they only even start roughly 1 in 20 of them.

They're all hanging on a rack slowly traversing down the line, and they'd randomly pick one at a station, hook up fuel/power/computer, start it up (open headers), rap it a few times, disconnect it and box it.

Now I'm sure some engines are exceptions to the rule (LS9).

FYI, I don't think royal purple even meets new oil standards. I would use a SM or better rated oil from pennzoil or valvoline and save yourself some cash and motor problems. I would not use RP in a old lawnmower.
