I mix benol and Klotz Techniplate, make sure you get high grade methonal 99.9 percent pure. The next grade down is 98.5 and apparently terrible for your motor. Also make sure you get good quaility nitro too, we have had issues with poor nitro turning the fuel black when mixing with Nova oils, not the oils it was the nitro.
I think the nitro comes from Grace Chemicals but will need to check on that.
Also Roelof I know you mentioned that you got your last batch of MSSR at a car workshop in the UK? If I can get my hands on Castrol oils I would be mixing with that, I hear its brilliant. Do you change head clearences with diff fuels? I am sticking with 0.7mm which seems to be safe.
