Thanks Bikenut !
Just a few years ago I would have agreed with you whole heartedly that oils are much better today that a few years ago.... however.... the dreaded EPA has mandated higher fuel mileage figures for cars to the point that manufacturers are using every edge they can to gain a precious few mpg. One of the things they are doing is having the oil companys reformulate their engine oils to reduce fluid drag. A fancy way of saying the oils are now thinner than they used to be. I thought I would never see the day when there was a 0w30 available but there is now thanks to the EPA.Smeghead said:I must admit to staying to the recommended intervals on my VFR as I use a high quality oil. If a bike is thrashed at track days or whatever it makes sense to change it sooner as it can be the first indication that you could have a problem. It all depends on your circumstances but as engine oil has been continually developed and is better than 5/10/20 years ago, it is a waste of money to change it more than is necessary. Just check it between changes.
