Guest mjames Posted September 7, 2010 Share Posted September 7, 2010 Hello to all, I am the proud new owner of a 52 Chrysler Windsor with the straight 6 and fluid matic trans. My question is, what type of gas should i be putting in it. Should i be putting in an additive to compensate for the absence of lead. Thanks.I am sure this is just the first of many questions i will have and want to thank everybody in advance for the knowledge and expertise that they share.Mike Link to comment Share on other sites More sharing options...

Usually whatever additive your local store carries. read the back of it some additive is concentrated Differently . I think its 1OZ per 10 gallons the good additive.Just read the back. you should be fine Link to comment Share on other sites More sharing options...
mrspeedyt Posted September 7, 2010 Share Posted September 7, 2010 i use the gas 'as is'.... regular unleaded unless it 'knocks'... then premium. once in a while i run carb/fuel injector cleaner thru... 'seafoam' seems to be good. you don't need a lead subsatute (pardon the spelling). Link to comment Share on other sites More sharing options...

Rusty_OToole Posted September 8, 2010 Share Posted September 8, 2010 (edited) Your engine was built to run on unleaded gas of under 80 octane. Today's regular 87 octane gas is plenty good enough. High compression overhead valve engines needing leaded high octane gas were just coming in when your car was built. It is not one of them.I would suggest, in the interest of longevity, you could add some upper cylinder oil to the gas, such as Redex, Marvel Mystery Oil or similar brand. This will reduce wear on the valves, cylinders and piston rings. Edited September 8, 2010 by Rusty_OToole (see edit history) Link to comment Share on other sites More sharing options...
Guest mjames Posted September 8, 2010 Share Posted September 8, 2010 Thanks rusty, i will do that Link to comment Share on other sites More sharing options...
Spitfire8 Posted September 10, 2010 Share Posted September 10, 2010 In a similar vein, has anyone tried running a small amount of 2-cycle (outboard?) oil in the gas to provide a bit more upper cylinder lube and protection against "dry" starts?

Rusty_OToole Posted September 10, 2010 Share Posted September 10, 2010 Haven't tried it but sounds like a good idea. Link to comment Share on other sites More sharing options...
