It would only be a waste if you did not run the oil to zero life which in the case of a synthetic would normally be more than double that of conventional. However, the price difference between the two is not always double and therefore it would not be a waste of money, but instead savings.
I agree wholeheartedly if a person extends the oil change interval otherwise why bother.
There are many factors to consider,first is cost. I haven't paid full price for a jug of oil in years,so in reality I'm buying ultra for the price of PYB.
Now throw in that ultra can run out to 15000 miles pretty easily in most vehicles under most driving conditions but there are exceptions,but I'm not one of them.
Under these conditions using a synthetic is an absolute no brainer. However my bikes are all using conventional rotella and its a cost based choice.
I'm not comfortable running any oil beyond 5000-6000 miles in my Harley. At start up the pistons are very loose so rest assured fuel intrusion is occurring.
Now let's consider that the oil can achieve 300f temps pretty fast in slow moving traffic but once the road opens up the oil cooler drops the temps to 200f,so that extremely quick temp fluctuation coupled with oil getting fuel diluted and evaporated in a short time means the oil is getting worked pretty hard,and I'm just not comfortable with the 10000 miles I'd have to ride if I was going to use a synthetic.
I'm also disgusted with these v-twin oils with tags at 16-20 bucks a quart. I get rotella for less than 5. In fact I'd need to get 15000 miles out of a v-twin oil for it to become cost equivalent,and I've seen used oil analysis where rotella was still serviceable after 5000 miles so I've picked that number as my safe cut off,and the cost doesn't bug me while I'm riding and enjoying myself. If I was still paying 70 an oil change with filter that's all I'd be able to talk,and rant about.
So in conclusion both forms have their place. Different applications as well as cost are factors that need to be considered if one wants to feel as though they've made the best decision they could have.
I'm not going to sacrifice protection because I'm cheap however I will explore every avenue available to me and when I can achieve comparable performance for less money,even if it means more time wrenching as long as my cost per mile is lower than the alternative then I call that winning.
