Its an aby engine and wanted some info on what oil to use and when to change it and any other tips on running it in.
Any help would be great.

Liam,

When I did mine I used some decent mineral oil for first 1000 miles then put fully synth in

I agree decent mineral oil for the first 1000-1500 km to get every thing bed in
then fully synthetic

fully synthetic in the begining will avoid enough friction to get nice bed in.

Yes mineral oil for at least the first 1k miles.

I always dump the oil, change the filter, and refill again with mineral oil after the first 50 miles, and again at 500 miles. Probably overkill but I tend to be a bit a.n.a.l about these things.

Thank you all for that.
so what mineral oil do you think is best?
Also what speed, revs do you think is best.
I have not took it passed 3000.

thanks

I would advise that you use a good mineral oil for the first 1k miles or so, then go on to a good semi synthetic oil for another 2-3k miles followed by a decent synthetic oil like Millers 15w60 comp oil

I have always used Castrol GTX to break a new engine in.

Yep, A bog standard mineral 10W-40 grade engine oil should be fine for running in.
