First oil change

pomidor · L Plate Warrior Joined: 25 Mar 2016 Karma :

Hi everyone, I just bought a budget Skyjet (;
Its brand new apart from 85 miles on the clock and 9 years in the shed.

So, after how many miles do I need to change olil for the first time?
Can I do it on my own or it is better to take it to garage?

Do I need to top it up with oil until this first change?

Thank for any advise

I'd do it now. The cheapest generic 10W40 from your local supermarket will exceed what it was designed to run on.

A Skyjet what? SJ125-23? Looks a bit like a CBR125?

If so, at that age it'll likely have the CG125 pushrod copy-engine. Most things that apply to the CG will apply to the Skyjet. It may or may not have a drain plug right under the engine, or it might just have the big drain plug on the side with a mesh filter behind it.

See: https://hondacg125.awardspace.com/oil.htm

Warm up, drain, refill, couldn't be easier.

Sitting in the shed for nine years? I'm not sure what checks you performed prior to handing your money over but I'd get a manual and perform a full service just so that you can then have a recorded list of when everything was last adjusted, lubed or replaced.

Taking the bike to a garage / trusted independent is the easy option but is always going to be far more expensive that the job at hand should ever really be to do since you're paying labour costs. Also taking the bike to a shop never really teaches you anything. I'd advise one of two paths (1) take it a garage to get a full service and do everything on your own from there on out (2) buy the manual and tools you'll need to perform a service and then spend the time checking everything over. The second option is preferable since your knowledge grows alongside your tool collection.

Take whatever route you feel comfortable with and have the money for.

It is exacly SJ125-23 with FM156 engine.

I had have a Honda CG, which was stolen right from my doorstep
Since that I can move my insurance policy to another bike, but it would not be insured for theft, thats the reason I bought this Skyjet bike. (it costed me same money I have been refunded from insurance - 450 pounds for "brand new bike" - it is still not registered with DVLA - I am doing it right now)

I have a Castrol 15W40 engine oil, which I used for my Honda, but it is not even a subject in a manual for this bike, which is imo strange.
Should I buy exacly this 10W40 and just change the oil straight away?

I know that those questions might sound silly but I am still totally new in biking world.

I have seen it running when I came to see it before buying. Bike sounds fresh and clean but I have no other Skyjet to compare with, so I would stay with my sense and trust in people.

Thanks for every type of advice! (;

15W40 will be fine as well. Unless it's fancy car oil with friction reducers, but if it was fine in the CG it should be good in the Skyjet.

I might hesitate to use Magnatec, depending how much snake oil they've actually put in it. Really, for basic engines, the cheaper the better. I've just bought 5L of Lidl's joke brand 10W40 for a whopping £11.99 and it'll be going into both my bikes.
