Premium Unleaded in '76 1600?

[ByronRichesMk1]

Just wondering guys whether or not running premium unleaded fuel in my mk1 would cause any problems?
The car itself is a 1976 1600 8V, & is running on regular unleaded fine with no additive.
So, either that.. Or should I be putting a lead additive in my fuel because of the age of the car? If it is any help the car is currently bone stock, so it's running a Solex carburetor.

I am pretty close to 100% sure that all MK1s have hardened seats are are capable of running unleaded without additives. If you use 95 octane all the time, then you should be able to bump the timing a touch if you want, to get a bit of extra go.

some of the mk1's had hardened valve seats but they do still suffer from valves seat recession regardless. For the cost of upper cylinder lubricant (buy it in bulk) it is well worth the $1 a tank rather than a big bill in a few years. I use 98 in my mk1 and have always had 50ml of upper cyl lubricant in every tank and suffer no valve recession for years now. Motor before this when leaded first go phased out ended up stuffed from recession.

Thanks Volksee.Where abouts could I get hold of this lubricant? Standard auto places like super cheap or auto one? Sounds like a very good idea to me, plus for that small amount of money per tank too it seems like no brainer!

You're probably not going to have any benefit from running premium over regular unleaded.
Either way, the lubricant is a good idea as a preventative measure, but as for getting more oomph out of the engine, premium won't do this as the engine isn't tuned for premium.
