My brother-in-law tells me that because my engine is from 1966 when gas was leaded, I may now have to put in an additive every time I gas up.  Please tell me, is he right?

 He is correct.

I've been doing this for yrs. but I only put the lead additive in about every 3rd. tank [ unless doing a long haul on hwy] but Octane booster goes in every tank, due to compression ratio. Lead additive helps the valves from not "hammering themselves into the seats" on long runs at speed, may not need it if just driving in town??? I also use ZINC additive in the engine oil [LUCAS] as modern day oils don't have it anymore!!!!!

Thank you ground pounder & dualquadpete. I guess I'll look in my local Canadian Tire for those additives?

Thank you again. I took your advice and bought the additives.

All,

I've never had too much luck with any additives you buy off the shelf in Canada. If the additive actually has the stuff you need like lead, they can't sell it to the public. Most of the "octane boosters" are just cleaners for the upper cylinder to eliminate carbon hot spots. The only exception I've seen is Racegas, the really expensive mix. This guy does a reasonable job of explaining the science:

you could buy all the "lead' additive you want but the real fix is to take the heads to the machine shop for a new set of hardened valve seats and a new valve job

upgrade the seats or waste the money buying the additive -- same money but only one way gets a return on the investment

eventually you're going to end up paying the same amount buying additive .. and then you'll go past that amount buying additive ..

I would also window shop the aftermarket heads - look for something simular to what you really need and then you have some revelliant cost info on the brain when you go to the machine shop for a price too

in many cases these days it actually makes more sence to buy new complete heads vs fixing the primitive old junk

(I use "junk" in the kindest sence )

 Yeah...However just drive the dam thing chances are by the time it states to act up or tick you will have built another mill or saved enough for upgrades.

 

DjD check your p/m
