By accident..

My dad brought some oil in from work in an old oil bottle labled 10w40, now i thought it was abit left over from the car but no, it full on bloody diesel oil.

Now, I noticed strait away the clutch was fine before this, now I once know why. So, how can I sort this? New plates? Drain it off?

Can i used an engine cleaner addative? The bike has very little pull but can be ridden...

Ta all....

I've put diesel grade 10w40 in my bikes before, no hassle with me.

Just buy some proper oil. Buy extra though so you can flush the old stuff out.

Sorted.

10w - 40 Oil is pretty much the same, porbably some extra crap additvives for diesels.

To me its all a marketing hype. if its 10w - 40 for sure your be fine

Stop. Just stop it. If you want help, explain the problem. Take the time to read what you've written, it's gibberish.

Exactly what kind of diesel oil? For all we know "diesel oil" could mean DERV.

How do you know what kind of oil it is?

What exactly is the symptom on your bike? You haven't even said!

Have you touched anything else on it, or did you just change the oil?

But FFS, just drain it, replace it with cheap 10W40, run the engine, drain that into a clean container, put it back in the bike, repeat a few times, drain and replace with clean oil, then take it from there, it's not bloody rocket science.

Wow, this must be how Tef feels all the time. Shocked

I was just thinking about oil. Im doing a clutch change next week and was wondering if I should go for the expensive bike oil or the cheap car oil.
Im skin but don't want to save on the pennies and end up spending the pounds to fix things.

I've used nothing else but diesel engine oil in my bikes for the past five years or more. Your slipping clutch might simply be that you put too much in.

If you want some peace of mind just drain it out and put different oil in. You don't need to change the clutch plates or anything like that.

I have also run my bike on 10W40 for diesel engines for years. Supposedly a higher detergent content, and better at holding crap in suspension than a 10W40 for petrol engines. This is useful in a bike engine with a wet clutch, which will generate more particulates.

Check your clutch adjustment first, coincidences like that do happen. If you need to change it, don't use a flush or worry too much about flushing with new oil. Get it good and hot to drain the oil, move the bike around a bit when it has almost finished draining so anything caught in a nook or cranny will drain down, then refill with normal oil and ride. Allow a few miles for any of the dodgy oil to get mixed in/diluted by the new oil.

Job done.

It suspends them in the oil until it gets to the filter, where they are captured.

Vans usually use a car-derived engine and often use a light duty diesel oil, which is the same as a car diesel engine oil, which will also be suitable for use in a petrol engine.

Trucks use a totally different specification system and hence have different oils that have limited or no petrol engine coverage.

There's little chance that a 10W-40 will be full of friction modifiers since this isn't really a fuel economy viscosity grade.
