Question oil change after 1000 miles?

This is my first oil change. Is it a good idea to change it after the first 1000 miles? Or could i wait another few hundred miles or even till 3000 miles. any suggestions appreciated.

The 1000 miles change is becuase of the breakin the motor goes through in those first 1000 miles. Added friction and wear on the components becuase everything hasn't been smoothed out yet by rubbing.

A friend of mine said his oil was pretty much near black at the 1000 miles range. I can't say the way he drove the car in those miles but i'd change it at 1000 myself.

After that its supposed to be the normal oil change rate 3000 miles for dino oil and like 4000 for synthetic? (i'm not sure on synthetic for a suby my protege hits the oil change at 5000)

i heard to wait to swtich to synthetic until 7500-10,000 miles. but that is definitely inconclusive and there are swarms of opinions on it on the net

Well the debate is something like the car needs the lubrication properties of the standard oil (shrugs) i don't really pay attention to it. But i do know high speed high horsepower mini motors on RC cars or airplanes. Example, my .46 cubic inch airplane motor turns its crank at a near impossible 18k rpm and produces a whooping 1.0 + hp . So lets do a lil calculation and find out approximately how much hp per liter there is on this engine using blended oil for lube.

well 1/.46 = about 45 hp per inch.

1 cubic inch = approx. .016387 (according to website)

So we divide 45 hp / inch by .016387 and you get about 2748 hp per liter :D

Engine hasn't broken yet even with abuse oil blend probably works ;)

I mean these things basically run nitro mix of 15% or higher,. The benifits i know of on normal motor oil is it lubes better at higher temperatures (thermal breakdown) but leaves a varnish like deposit on the cylinder which harms performance after time. Synthetic doesnt leave a varnish but breaks down a lil faster.

The common solution now is to use a blended oil mix of synthetic and dino to give the lasting benifits of dino at high rpm (which these motors constantly run at) and no varnish on the cylinder :D best of both worlds.

Sugguestion: Use synthetic blend oil until the designated 7500 - 10k range then switch over to full synth. This gives the benifits of longer lasting oil changes but still has the same properties of the dino oil :D

just my .02
