Have I fucked up?

[Wafer_Thin_Ham]

By putting fully synth into my hornet because it's all they had. I usually run semi-synth?

They didn't have any semi in the right weight so I just picked up the fully synth. I figured it would be fine, but someone off another forum said you shouldn't swap between semi and fully synth, so it's got me doubting myself.

What's the opinion on here?

Thanks

BH

I think your fine, dont know of anyone having problems switching between the two so long as they are the same weights

I've swapped between the two many times with no problems.

Phew, thanks for confirming what I thought!

No harm will have been done.

Similarly, mixing semi- and fully-synth causing it to "congeal and thicken" is a load of codswallop.

I think this comes from a while back back when mixing Mineral 2t oil and Synthetic 2t oil, would congeal. Not a problem nowadays with modern oils but certainly something to be aware off then and would result in having to flush the crankcases for ages or split the motor to sort out.

Hi

Synthetic oil is basically processed mineral oil. Shouldn't cause a problem (only know of one person who had a problem, and that was my father with gearbox oil in his car).

Stuff you should not ever mix with mineral oil (of the synthetic or non synthetic varieties) is castor based oils.

All the best

i dunno where i get this idea... but i thought semi wasn't as good... and that you were ideally meant to run full but if you ever ran with semi then from then on your meant to run semi? i have no idea wheres thats from but remember being told it, maybe a classic car owner?

I did the same with my Hornet a few weeks back, it's not a problem.

It will be fine, although I did that once with my FMX, it didnt help my gears at all (seemed to jump more often, not catching or something). Changed back a day later and my bike is still fine 1 year on.

Agreed with Keith, there is so much crap written about oils its untrue. I've been guilty of oil paranoia myself several times on here without a doubt.

Yes there is some complex technology involved, but people get way to hung up on things.

Best advice is to do some of your own research on oil (non forum based) and understand what all the codes and descriptions actually mean. Then make your own choices.

Agree that synth wont affect the engine, but what about it causing clutch slip, or is that a thing of the past these days?

My mate and his cbr wont go anywhere near synth for this reason alone.

Synthetic oil doesn't cause clutch slip. The only oil I've heard of (and experienced) causing trouble is castrol magnatec.

For the record I've been exclusively using car oil for the last 4 years or so, a mix of fully sun 5W40, mineral 10W40, mineral 15W40. Some for petrol engines and some for diesel engines. The stuff for diesel engines seems to be best. I presume this is because diesel oil is better at holding particulates (general crap) in suspension, and in a bike engine where the oil is in contact with the engine, clutch, and gearbox, there is a lot more scope for crap to get into it.

Last time we bought some oil,
we were told that diesel oil is very thick,
as we bought the thicket petrol oil, pretty close to the diesel consistancy. Cars obviously
