Last minute rush!!! Is 20W40 oil ok?

Duh,like every oil has additives,I don't think you'd want oil without additives in your motor! ''performance enhancing additives'' - where do you read friction modified there?

True. I read "performance additives". If they refer to friction modified or not, I don't know. Just erring on the side of caution, in that if I would hesitate to use it then I would not recommend it to anyone else.

Deja Vu Velox? Haven't we been here before?

I hope you enjoyed the ride,with some good oil in the bike.The Duckhams would of been fine,20/40 is ok and I doubt it's friction modified,plus you confirmed that.There is a far greater improvement in power and ecconomy by going to a 10/30 or 5/30 than by making a 20/40 more slippery,so you won't find the thicker oils friction modified....the small amount you were going to use would have no effect anyway.

Hmmm - me doing a last-minute, oil changing, SOS post? I'm not sure but I wouldn't put it past me. Cheers for the history lesson mate! Read, noted and stored in cerebral receptical.
Yeah - the bike survived the ride fine - didn't spontaneously combust or drop 3 gears by mistake or vomit oil out the headlight or anything. It's really due for an oil change though so I'll sort it properly this week anyway!

Don't all SF oils have friction modifiers?
They do according to 'the oil guy'.
