Just bought a1962 220seb convertible - What fuel???

I just bought a 1962 220seb convertible (64000km original mileage). I'm not planning on driving it much, and not at all until next spring (I live in the snow belt).

What should I use for fuel? Do I need to find leaded fuel? Do I use unleaded and add lead substitute??

What's the best solution?

Thanks
Matt

I'd go with premium unleaded and add some lead substitute. Also if you're going to store it, but Stabil Fuel additive. Squirt some oil into the cylinders too.

Some people reccommend spraying antifreeze on the block/tranny as well, but I would never do that.

As for fuel, make sure you add some lead substitute.

No need to use a lead substitute. Save your money. Mercedes has used hardenend seats since the 50's. The manual probably calls for premium fuel, but premium fuel in the early 60's is about the equivalent of today's mid-grade. I've been using unleaded in mine since I got it with no issues at all. I did use modern premium for the first few years until I was "educated" about my fuel choice. The car runs fine on mid-grade. MPG is about the same with both and there is no knocking with either one. I have not tried regular unleaded and probably won't, although lots of owners say they have no problems with it either.

There is a retard lever on the distributor for just that purpose.

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant

Hello there

Fuel quality here in Ireland is generally regarded as being below that of the UK and USA. Furthermore - putting low octane unleaded petrol into older engines cant give the same results as the the fuel available when the fuel delivery/ignition system was carefully designed to deliver max performance for that time.

Recently my brother in law - a mechanic and classic enthusiast told me of a product he is fitting to his 1971 Rover P5B 3.5 litre.

http://www.fuelcat.co.uk/mainpage.html


This inline fuel catalyser apparently changes the molecular structure of the fuel enabling it to burn more fully.

He came across it through a friend who has fitted to a large S class Mercedes - his friend has put one into a high performance Subaru - performance in both was dramtically increased.

With it older engines can run on unleaded without adjustment . .

I'm waiting to see before I fit one to my 1973 350 SLC

If it works its hassle free and cheaper than lead substitute etc

Have a look yourself at the website . .

cheers

Pete

i started with low test when i got the car, it did knock and sputter, but i didnt do a tune on the car at the time. now that i have the low test knocks some, so now i moved to mid test or high test. knocks are pretty much gone. i read thru my owners manual when i recieved it from ebay and it did mention octane at 96. i have not added anything other than injector cleaner and z-max. a general aviation mechanic swears by z-max,although its not called that in aviation lingo, sez just using the stuff on his rental airplanes frees the pistons when overhaul comes around, otherwise they are just a B!^(H to get out. also noticed the first 2 oil changes produced alot of carbon and build up in oil and filter after change. oil is clear now. i guess the fuel helped loosen crap in the induction system, valve, intake, etc.

that cat fuel sounds interesting, will bring it up with a few fellow techs at work.
