Best Evo Mineral Oil Around

Best Evo mineral oil available. My oil temp runs from 150f to 200f so I need oil I can count on 365 days a year. You want my hard earned money? Be reliable...these guys do just that.

70 weight blues.

I normally use PENNGRADE NITRO 70, you can not beat it down here in the 100 degree Fl heat but JP was out of stock. So this was my next choice. We will see how the old shovel likes it!

A good quality motor oil for my Harley Davidson Sportster 48. I have used this oil many times and the quality is good for my engine. The price is compatible with the Harley Davidson motor oil.
