Default Lead Additive - Will it clog a fuel filter?

I had been using lead additive, 1 can per tank of gas when I filled up.
Can this stuff clog up the fuel filter? I put a new fuel filter on in the fall
And a few weeks ago the car started running like crap (you can read all about it in other posts under my name.) I by passed the filter and the car was back to normal. I cut
the can in half to look at the filter and did not see anything of interest. The only thing
I can think of is that the additive I was using caused the problem. Any comments or experiences to share?

Why would you want to use it? No reason for it. These cars run great on unleaded. Change the filter and run unleaded and enjoy yor car!

Otherwise the PICA BALLOON will be following your Vette around.

Speak for yourself. Mine likes the lead this time of year. A little real tertraethyl lead and the hot weather knocking goes bye-bye.

JB, where do you get real tetraethyl lead these days. I thought it had been banned by the EPA and unavalible for years. I know there are a lot of octane boosters around, but none that contain real lead.

Thanks, Ralph. l

I have an all original 69 that has 46K miles on it. I assume it has not had any head work done to it thus the lead additive.

I actually bought a case of Real Lead from a forum member, and I've been using that, but it's readily available online. Here's one place: http://www.kemcooil.com/product_info.php?pId=61

I've also used leaded blue avgas in the past, but that's technically illegal, though all it takes to get the stuff is to show up at your local commuter airport with gascans and tell them you use it in the kit plane you built.

Well, if it's a small block, chances are very good you don't actually need it. Unless you're getting pre-ignition (knocking, pinging, valve clatter), it's probably a wast of money. A lot of the engine rebuilder types here on the forum will tell you that the regular old factory valve seats they've seen over the years have held up just fine with unleaded.

Adding lead to gas should only mess up the O2 sensor and the Cat converter, if you have them.

Av gas is 100 low lead.

I ran my 66 327/350 with a lead additive for 10 years and no problems. These cars originally had lead in the fuel so it must be gas soluble.

I ran unleaded Amoco in all my Chevys in the late 50's and 60's without any damage. Supposedly the valves and head sealing surfaces for the valves were not hard enough to use unleaded. From my experience, it is a myth. Even my Triumph TR-3 and TR-6 all ran fine on unleaded with no engine problems.

The only time our older motors run into problems without the hardened exhaust seat is if you do alot of towing. I assume you do not so adding lead is unnecessary.
