Changed oil the other day and decided to try some Valvoline straight 50 weight racing oil. I had heard that it made the old evos run a little quieter. It did on my bike. A lot of that annoying ticking is gone. May try straight 60 when we get in to mid 90's Mississippi summer. Only down side I could see would be running this oil in cold weather.

 

I run 60w in summer, quiets the engine and keeps that pesky oil light out.

 

Good to know, gonna try it this summer. It gets some kinda hot up here. I know it gets hot in St. Pete too.

 

Straight 60 will be going in mine next oil change for the summer months. Straight 50 or 60 is almost a requirement for the deep south boys and old evos.

 

Straight grade oils are only suitable for warmer climes! I used them in my shovel, way back when.

 

Oh $hit...........haven't quite recovered from the last oil thread

Straight 50 was our "winter oil" back in Texas in Shovelhead Daze.

 

Anything wrong with Valvoline race oil? It has a higher Zinc compound.??

 

That is what I use.
