i've heard all kinds of opinions on this one, and i couldn't find a good thread that answered it. so what oil do you use for break in: conventional, synthetic, or a conventional synthetic blend?

honetly it doesn't matter, old school thinkers will tell u conven, but the synth is better overall anyways and u should always use synth if u run hard in th end. I don't think anyone can pull evidence that conventional is any better for break-in.
It doesn't lubricate as well... Which you actually want. If its too slippery you won't seat the rings cause they won't grind away any of the honing pattern.
Switch to synthetic after the first 10 miles at least.
And by the way im not old school.
10 miles and switch to synth................ sry sounds like bull shit to me.
10 miles and ur motor no can use another type of oil.... yeah right, like it really made a difference in 10 miles.
the rings r gonna seat no matter what. if thats the thinking behind it unless someone can pul charts proving conven creates crosshatch (witch comes standered n many kit out of the box btw) then i don't buy it.
btw this argument goes on forever... i will stand by it doesn't matter 4 ever.
*pull charts proving conven creates crosshatch significantly sooner that synth...
typed too fast lolz^^^^
The rings will seat with in the first few rotations. If they didn't there wouldn't be any break in. All there would be is this block of metal with a round thing in that can't hold any type of compression.
Just use conventional than switch to syn. YOu will have to drain you gas tank when you switch. If 2 stroke oil is like 4 stroke SYn and Con will not mix and separate which would lead to some weird shit.
Sorry but all this drive 200 miles to break it in is BS. I let mine warm up rode it soft for a few miles than opened it up and havn't stopped and my piston is fine.
i totally agree with it breaking in within the first couple of miles. i was just curious which type of oil i should use for those first miles. should i just pick up any shitty 2 stroke conventional oil?
use the good stuff (synth)... draining the tank to switch.. WTF... sounds like a heap of extra work and possible lean mix circumstances to even be worth it.. and worth what? no one can prove conven is any better for break it. but synth is obviously better for hard running conditions.
i've nvr used conven ever and my bikes haul ass.
but if ur worried use watever, honestly u should just use the oil u plan on using for the life of the bike always..
just use whatever oil
oil is oil for our purposes.
this arguement only has any weight if you are talking about enduro or dirt bikes
castor is good and smells grrrreat....
ten miles isnt enough? how many times do you think the piston went up and down to get you ten miles away? thousands.
i wouldnt worry about it too much though. just do your best not to seize and just try to be on the safe side. upjet till you fourstroke then come back one or something, and dont let it get too hot.
GL
who cares what oil you use. break in? get it tuned right and WOT =)
it doesnt matter, the mix and jetting is far more important.
the myth is from WAY back when synth oils were new and some thought they had problems sticking to metal.
It doesn't matter.
An observation I've noticed. I took the head off mine after running 300miles on conventional oil, and their weren't any hone marks left in their.
I'm used to tearing down motorcycle engines for one reason or another after thousands of miles, and you still see plenty of crosshatching. I'm thinking 300 miles on a small engine like these like thousands on a larger cc engine. I'm running synthetic now, so i can get some real mileage on this before I wear the cylinder all the way too the cooling fins.
The Castrol web site has this to say:
# MYTH: You need to allow a break-in period for new vehicles before using synthetic motor oil.
FACT: In the past, it was recommended that conventional motor oil be used for your first oil change to allow for some controlled wear to break-in the new engine. However, with current engine technology, a break-in period is not necessary. You can use synthetics immediately.
Now, if you feel your kit was produced with this same "new technology", use synthetic.
Myself, I would prefer to breakin with conventional oil, as I am not savy enough to know if these kit makers are capable of the same degree of manufacturing as a major automobile manufacturer.
i second jensaroo and jonv. I wanted to be super careful and makes sure everything gets honed done nice and easy. conventional oil the first tank or two, then switch to the good shit.
