Oil resistance isn't too much of an issue, however, fuel (presumably petrol) is. I used a two part laquer years ago made by "Rustins". Not sure whether it's still available, but I'm sure there will be something similar out there.

I tend to oil mine with Osmo PolyX being the usual choice.

Rustin's "Plastic Coating" sounds like what B0'son describes but a bit too glossy for my liking but is more durable than the oil.

After the Rustins coating has completely hardened you can flat off lightly with 1000 grade wet and dry used wet, add a bit of soap liquid to save the paper clogging.
This will quickly leave a matt finish that still has the full protection provided by the product.

A bit late in the day, but I use a home brew furniture polish that resists oil and fuel quite well. It gives a matt sheen when buffed up.

1 part pure turpentine
1 part raw linseed oil
1 part white vinegar
1/4 part methylated spirits

Shake well and apply with a soft cloth to the bare wood. Several coats can be applied in fairly quick succession. I usually aim for a minimum of 4 coats. Keep it sealed in a small honey jar or similar and it will last for ages. Just shake again before using each time.

That sounds like a bit of a witch's brew , I have ordered some Rustins , sounds as if it might be good for my kitchen work tops as well

Try the finest grade of steel wool when reducing the shine, lubricated with furniture polish. It is better able to fit into mouldings etc than wet & dry. And rub in circles wherever you can, rather than to & fro. I use grade 0000 - available off the shelf in the village.

Cheers, Tim

Polyurethane varnish seems to be pretty good for resisting fuels and is tougher than most varnishes.
