| Says they are all of High Viscosity Index and Light Red in color. No viscosity weights are published however even in SDS. As a matter of fact PJ1 has the same SDS data sheet (for and that includes) 6 different weights although they publish that they have 8 different weights.

| + | Independent testing (not affiliated with Harley Davidson) was done on HD Type E fork oil. ((shanneba of the XLFORUM http://xlforum.net/forums/showpost.php?p=5740911&postcount=1)) \\ | ||
| + | Based on the data from that testing, the chart below was created using the [[https://widman.biz/English/Calculators/Graph.html|Widman "Graph your oils"]] web page. \\ | ||
| + | The chart is a comparison of HD Type E, Red Line Medium, Red Line Heavy and the 75% RL Medium / 25% Red Line Heavy fork oils. \\ | ||
| + | Temperatures from 0C / 32F to ~ 50C / 122F (the data on the web page goes up to 80C). \\ | ||
| + | You can see clearly how the higher (442) viscosity Index of the Red Line Medium fork oil changes viscosity less at colder temp. \\ | ||
| + | This should give a more consistent suspension at lower temps. Again, trust your own results / testing. \\ | ||
