Lucas safeguard
 

So been seeing this stuff at work, just wondering if it's safe to use in our engines when you're already pre mixing with idmitsu or if that's to many additives?

Safeguard™ Ethanol Fuel Conditioner with Stabilizers : Lucas Oil

No need, don't waste your money.

Correct, no need. Ethanol can cause corrosion problems on metal that isn't equipped to handle it, and E10 is the most you will see at the pump and has been proven not to cause corrosion problems.

The only reason you would ever need something like this is if you are running more ethanol than is in pump gas AND have not properly prepared your fuel system.

Not a concern at all for street cars on pump gas.

I see, thanks for the info guys!!
