Re: Do I need LEAD ADDITIVE or not?
You need a TCW-3 oil at 50:1 ratio with 87 or 89 US Octane gasoline. You need to add a fuel stabilizer like Sta-Bil whenever you add fuel. You should add a de-carbon product like seafoam as well.
Besides being bio-degradable

, 100% synthetic TCW-3 oils have a higher flash point and produce less carbon and plug fouling for most users.
