Running a classic car on unleaded petrol

Recommended Posts

Hello Forumers, it's Mr Bloke here. Well...

 

...I have searched previous threads for this but have only been able to find some really old ones that do not really answer my questions.

 

I am currently in the very early stages of preparing a (don't really know if this is regarded as a classic in these circles) to be road-worthy. It has been garaged since and has never been run on petrol.

 

My questions are:

 

Is it worthwhile considering having toughened valve seats fitted in order to run on unleaded petrol bearing in mind the car will cover less than 1,000 miles a year, and if so any ideas how much this will cost?

 

Alternatively, what fuel additives would you recommend and where are these available?

 

Thanks

Just shove millers or similar in it. Or shell do their own brand of fuel additive. Not worth the effort to convert considering the mileage you will be doing.

Thanks for help. Do these fuel cats really work? I've heard that they don't do all they claim! Anyone have first hand experience of them?

be cheaper in the long run to have the head done.

 

For a 1000 miles a year it won't. 30,000 miles a year maybe.

Personally I've been using the Castrol version for years with no ill effects, and certainly no signs of valve seat problems.

In my case a Ducati and a Rover V8. Also used the Octane booster version when I had a higher compression ratio and found it cured my pinking problem; the engine was designed to run on 5 star.

Use the Castrol product, with octane booster in my Pinto Escort and had no problrms at all.
