7.5-8k, with whatever 20w-50 full syn is on sale.

 

watch the oil pressure, never mind what # but where it is on the dial during hot idle and cruise. Take note what mileage you start to notice the pressure lower than where it has been. losing viscosity. Time to change. Interestingly this occurs soon after the recommended 5k for me at least

 

VERY interesting Canuck....I never thought to keep note of this number duing idle and while riding. I will now be mindful of this.

Very appreciative of this board.

 

I like to change my every 5000 miles with Amsoil 20- 50.

 

I guess I'm old school, and wasting money. Change oil and filter every 2,500 miles. Using syn3 right now, going to switch to Mobil One V Twin at 5,000 miles. There is no downside other than cost.

 

5K or two years, whichever comes first.

 

Going to 5k mile intervals will save you money. The Amsoil may cost a 2-3 bucks more a quart, but you'll also be changing it almost half as often. It is hard to change the train of thought that you don't need to change your oil every 3k. Heck, my car recommends between 7,500-10k.

 

Been doing every 2500 miles ever since I owned Harley's. (15 years)

 

Red Line 20w-50 (3) three times a short season NNY, Shock proof in trans and Formula+ in primary.

 

All 3 fluids at 5K.
