Motorex oil is red , its the finest of the fine oils too. Penrite is aight , ask 50sbrotherhood1# , he ran penrite in his cases for a year. Bike still went fine.
People get too wound up about their oils my theory is:
Buy the best oil you can afford to throw out. Oil changes should be made more regularly than not , so dumping a 700ml's of oil you paid $25 for and haven't changed in a year isnt going to be as effective as replacing the oil every 3 or 4 rides or so.
I use Mobile oil , works sweet , cheap and never ever had a problem with it.
