| Must admit that if my Local Honda shop sold Mobil 1 and would do it for the same price as they do me the Silkolene I would use it as I did use it in my IL4 race bikes, but as I get the Silkolene at around 60% of the cost of Mobil 1 and when your racing with regular oil changes that adds up and with 5 years of running Comp4 on both road and track I see no reason to change |
