It's all dino oil, just how much refinement it has. synthetic is a marketing term.

 

You go 7500 miles between engine oil changes? Man you really trust your synthetic oil.

 

Pfffft, I know a guy who goes that much on Dino oil. Bike still runs.

 

Thanks I just about spit coffee onto my keyboard.

Hahaha that was awesome.

 

Is it true that synthetic can handle the higher heat?

 

I've used synthetic for a while now and I do run it 5000 miles. It seemed at first to show up leaks, but because it was thinner. The potential for leaks was already there. As far as the heat thing, an oil cooler doesn't help much when you're not moving fast.(think stopped traffic or downtown Chicago). I have had my bike shut itself down from heat on dino oil, but never on synthetic. The other thing I noticed is with the thinner synthetic, the trans seems louder than with the heavier oil. Just my 2 cents...

 

Get one with a fan. Problem resolved.

 

Sure before we were married my wife once ran her Chevy Cavalier 29,000 miles without changing the oil, just added some when the idiot light came on. It ran but I wouldn't recommend it. (same car was junked by 89,000 miles).

 

You are mistaken. A group 3 basestock is a refined conventional. Group 4 and 5 are man made. They are a synthetic molecule which is why they will exaggerate leaks because every molecule is uniform and identical. Amsoil,red-line and royal purple are all group 4 and 5 basestocks. Mobil 1's EP Line is a group 4 basestock but all the rest are a group 3. So is castrol syntec. A simple google search would make this information available to you.

 

This is a lot to read, but it is worth taking the time to do so. It is a page I found for a DR650, but it's a page on oil, and its ratings. This will also explain why some of you have had bad experiences with their clutch slipping. You used the wrong spec oil.

Scroll down past the first few pages which are only about the DR650 and get to the specifics of all different oils. I learned that some people use Diesel synthetic oil in their Harley's!!
