One area seldom touched on is advanced lubricants. Techline Dry Film Lubricant on all rubbing parts is one thing that can be done. Using Prolong Engine Treatment is another. I used Prolong in my race motors and never had an engine failure.
Mixed at 10% of the oil volume then add the oil to the fuel as normal. This is for the first gallon, then at 5% of the oil volume from then on. Oil bath clutch at 5%, other words 1 part Prolong, 19 parts clutch oil.
The bottle comes in two sizes, the smaller bottle labeled "booster" is the same stuff. You need so little the bottle will last a long time and it is quite a bit cheaper, about $8 a bottle.
Prolong uses the natural electric charge that is made from spinning metal to bond with the metal. Did you ever see the Prolong ad that they ran a motor without oil for a very long time without seizing? It's factual. Products like Slick50 were bogus and they settled a suit from the FTC for $10,000,000 for their lies. Prolong has never been sued thus substantiating their claims.
Start using it after the first gallon from break-in, don't use too much in the mix, doesn't help, and I'm sure you'll feel a difference.
