Guys - I can get 106 an 109 cam 2 race gas here. I have been mixing that out of cans in with the 89 I get at the pump on the water. I have had no issues so far but was told by one person that it is a leaded gas an may not be good to run. It could cause build up on the valves and lifters ? Do that sound right ? I know the race cars runs this stuff I can image they would if it was that bad. Any input ?
