Accidental gear oil in 125 motor?

[FinnishBear]

Hello, I own a 2014 Lexmoto ZSX 125 (carb) and realised the oil was a bit low. Went to Halford's and got some 10W-40 to top up, but realised it said gear oil on the bottle instead of motor oil once I'd poured some in. Below is a link to what I got.

Google is really confusing me as it says that gear oils have some other sort of ratings like 75w90 and that 10w40 should be engine oil, but the bottle says gear oil.

Should I just let this oil burn out (as I read it will since it has something like a lower boiling point) and top up with motor oil?

Thanks for your advice

I’d drain it out and start again myself. I can’t imagine your bike needing lots of litres so it shouldn’t cost a fortune - and what cost / price for your peace of mind?
Ultimately though, your bike, your risk.

How much did you put in?

The data sheet for your oil is interesting. It says it's Comma oil, and use is "automotive engine oil", although that might be an "umbrella" descriotion.

Edit: I *guess* your bike takes a litre of oil. You should be able to buy 4 litres for less than £30. If you're topping the oil up, it's probably not that far from needing an oild change anyway, so it might not cost much to change it now.

Thanks for the replies. To be honest I was considering changing the oil, so far I've added maybe 150mL. I'll check the manual to see how much it needs and maybe change the filter while I'm at it. Just not sure how to collect the oil since i don't have a drain pan but I'll figure it out.

I've also got a week or two where I can't use the bike since I need to return some crappy boots I got for a refund (damn mail being slow) so I'll have time to do it.

Cut a rectangle in the side of an empty 4 or 5l plastic container and use that as a drain pan (I used to use an old oil can, but if you don't have one, all sorts of things come in 5l plastic bottles). Also makes it easy to pour into a different container via the spout so you can take it down to the oil bank.

Or a disposable tinfoil tray for roasting tor roasting turkeys etc.

The only possible snag I can think of is that gear oil may contain
friction modifiers which might cause a bikes clutch to slip.
This is why most car engine oil isn't recommended for most bikes
but you're probably fine.
You only need to catch about a litre of oil so cut a hole in the side of
a used 2ltr milk container if nothing else comes to hand.

Oil is misleading scam-full business.

The only one I trust is snake oil.
You know what is in that.

Surely the product is intended for something like my 2-stroke DT? I have a gearbox that is separate from the cylinder 'cos... like... errm.... 2-stroke You know what I mean But the "gearbox" does contain the clutch on most bikes. Don't think the Chinese have started ripping off Ducati dry clutches lately

Anyhoo, if it was some sort of "car" oil you could maybe panic a bit, but not over 150ml. Actually the "panic" should be what sort of oil was in the bike to start with: ~5 years it's plausible to be the factory mineral (another cynical jab at Chinese 125 owners, soz!)

IMHO it's good practice to keep the same brand of oil going for your bike. Don't know what's in there? There's your cue to dump it and the filter and put known stuff in.
