I have made an error.
Being new to this I wanted to do an oil change on my XJ600s, but I didnt know which oil to get.
The Haynes Manual suggests 10W30 or 20w40 depending on the temperature. I could not find either at any local suppliers. I didnt go to a bike shop.
I ended up using a 15w40 Castrol Oil. The oil was Castrol GTX Semi-Synthetic High Mileage.
The mistake is that I used CAR oil. I know I should not have done this, and know better for the future, but to remove the oil now means emptying and filling the bike twice to flush the system.
With the GTX Car oil be OK to leave until the next oil change in 6 months? It will have done about 2000 miles by then. I have ridden the bike and the clutch is NOT slipping. In fact it rides very well, and much quieter than before.

These days, I always use bike oil, however, a few years ago I had a Suzuki XN85 Turbo which I ran on cheap comma car oil.
I used to change the oil every 1000 miles and never had any issues.
I doubt there is any difference between bike and car oils these days although I sleep better knowing I have used bike oil in my bike.

I always use bike oil - semi synth from Hein Gericke is cheaper than Halfords semi synth car oil.
I also know that there *is* a lot of difference in the additives between car and bike oils.Two of my clients are oil blending companies that blend oil for a few of the big names out there, and as I was connected to one of the sites to correct some dodgy data, I had a look at the bills of material for some of the different oils they supply.The base oil is the same, but the additives etc. vary wildly.

Agreed there are differences, but I think a low-stressed motor unit like the Divvy 600 will tolerate pretty much anything. Obviously the engine will be quite happy on a car oil, it's the gearbox and clutch that might suffer. But the box is pretty much bomb-proof, and if the clutch isn't showing any signs of slippage I'd be happy.
By the way, I personally would be happy to leave a modern oil in for a year or 6,000 miles, which is what Yamaha now use as their standard service interval for all their road models (not sure about exotica like the WR's). That's unless the bike's being used for short journeys, in which case 6 months is probably wiser. I'd always change the filter at the same time.

Surely they put friction modifiers and anti sludge additives in car oils, which are not put in bike oils, due to bikes generally having a wet clutch, so car oil of the same type must be better, just more likely to promote clutch slip, but as this has never happened to most people using semi synth car oil, then using semi synthetic car oil will be ok |

you get anti sludge additives in bike oils too, along with shear-stabilisers and stuff.
Both types have a lot of different additives - friction modifiers in car oils are usually put in to promote economy, rather than any other perceived benefit.I agree that decent car oil would do the job for most bikes, but it's more expensive than the stuff I use from HG, so no point in using it.
