[Spridgets] Fuel & Fuel Additives

[Dean Hedin]

I run lead additive.

The way I look at it is they have put hardened seats and better valve
materials
in modern engines for a reason.

The lead substitute is not very expensive; I think a bottle that treats
20 gallons cost $3.  Two or three of those bottles will do me for a season.

That's not a lot considering what it might avert, valves receding into the
head,
faster wear on the valve guides, etc...

It's not like they are selling the substitute because it doesn't do
anything.

I have seen worn valves out of an old 948 engine.  Valve faces do wear and
valve
guides wear faster.  If the additive can help reduce that then I think
it is worth it.

I have run my motor for 7 years with no lead additive.
The guy i bought my car from had it for 10 years - no lead additive.
His dad owned the from 1973 and never ran a lead additive.
I am not sure about the others in the group have experienced.
But my motor is stock and it was just taken apart for a rebuild.
The motor showed no wear on the valves , a little on the mains .
The cylinder walls were so nice they did not need to be bored out.
It was just hit lightly with a hon to clean them up.
I am running stock pistons in the motor again.
So n my opinion the additive is not needed.
If you have a street race motor you may need to harden the seats or run an
additive.
I am not sure it is even need with those motors.
I am curious how many people run a lead additive.
I know most people in my area i have talked to say it is not necessary.
