Hi everyone. Can anyone advise me if I should be using an attitive in the fuel that I use for my 1200 sporty. It is a 1989 1200 evo motor. I use unleaded in it but have been also adding about 1 mill per litre of additive, that is the additive used for motors that have not been convertered for ULP. This motor may be suitable for ULP at time of manifacture I am not sure. I have only had it for about three months and have not done a lot of Ks in that time but have used the additive during the time I have had it. The previous owner advised me that he had also used the additive so I continued to use it also. I would greatly appreciate any info that anyone out there may have re this. Thanks RAH002.
