Re: 7,500 Mile Oil Changes?
I do 6,000 mile oil changes on my car. I use Mobile1 and I also change oil filters between oil changes. All of my other rides, I use synthetic blend & change at 3,000 intervals.
There are people that will agree and disagree on 6,000 mile intervals. Using good quaility full synthetic oil & doubling up on filter changes has worked good for me.
Be sure your engine is broke in before switching to full synthetic & always use a good quaility oil filter (no fram)
Also, you might want to research brands. There are a lot of oil's claiming "full synthetic" but are actually petroleum based. Amsoil and Mobile 1 are true synthetic.
