New member here. Have already done a search so sorry if I missed something.

Anyone know if there are harmful (or beneficial) effects to using one of the lead substitute products in gas for a 2 cycle engine (Yamaha GP1300R)?

We have a gas tank which supplies gas to older engines (designed for leaded gas) and, hopefully, the GP1300Rs.

Thanks

After more research I found that lead substitutes containing sodium may "have an impact" on 2 stoke gas/oil mixes and fuel systems. Those containing potassium should be OK. I found no information on harmful effects of lead substitutes on engine mechanicals such as reed valves or bearings. As with many other retail chemicals, you may have to request an MSDS (material safety data sheet) from the manufacturer in order to find out what is in the bottle. By law, they have to send or fax it to you.

In short, for 2 stroke engines, lead substitutes do not help and there is no data (that I found) saying those containing potassium doing any harm.
