Hey guys, I've recently acquired an early '77 wagon with a 1600 EA71 motor with single carby.
Been searching on the forum but couldn't see anything about what fuel / additives are best for older Subies- anyone got recommendations?
- Is 95 or 98 octane better?
- Is a lead substitute required? e.g. Valvemaster, Nulon, Flashlube- which is best?
Since this model isn't listed on the "official" list of pre-1990 vehicles that don't need lead substitute, it would appear that it is required but I'd rather see what real people think

I'm also thinking of trying a fuel system cleaner- I've noticed the engine spluttering and loosing power sometimes so maybe the carby needs cleaning out. An easy first step would be a fuel additive like Nulon Total Fuel System Cleaner which has good reviews, but not sure if it would be suitable for this type of motor. Anyone have any experience with this?

You don't need lead substitute because you have aluminium heads. Engines with iron heads need it.
If the car has been sitting a long time, it would be a good idea to drain the old fuel from the tank. Also fit a new fuel filter, check for deposits in the float bowl, make sure jets aren't blocked, check for vacuum leaks and do a basic tune on the carb.
I have never used fuel system cleaner, someone else here might know more about it though.
Both 95 and 98 should be fine if everything is set up right and running properly.
