We all know that our 'old time' engines are not compatible with many of the modern fuel additives and that in many cases, such engines need "old time" additives such as lead in the fuel and ZDDP in the oil. A guy could go crazy trying to assemble the correct fuel additives and ignoring the bogus ones.
Therefore, I must ask - has anyone found a good one-stop shop fuel additive which will give an older engine what it needs and counteract the modern fuel additives which it doesn't need?
Thanks!
