I'm currently restoring the fuel tank (inside). I filled the whole tank with white vinegar and let it sit for 48 hours. The results are quite good. But now I need to treat the aluminium against corrosion. I plan on using WD-40 to coat the inside of the tank (I plan on using a lot of WD-40). After soaking for a bit, I'll fill the tank again with fuel (I think the best fuel for the CB500 Four is E95?).
Is the WD-40 a good protection against corrosion?
Is this the right fuel that I'll be using?
Thanks in advance!

Which bits are aluminium? Whatever you put in the tank will get washed away with the fuel fairly quickly. If it's just for storage, then diesel swished around is better. Those pits in the surface look quite deep. When you have finished cleaning, I would fill it with petrol before any painting, just in case of pin holes appearing.

Did you mean E5? Here in UK we only have E5 and E10

What fuel do you use?
Post by: Orcade-Ian on October 14, 2023, 02:06:25 PM
I think you will be referring to 95 Octane fuel, that is also available here. E5 here is 5% ethanol content, E10 is 10%. We would run a mile - or a few kilometres if we saw E95 on the pumps - that would be 95% ethanol and our old Honda engines would probably dissolve before our eyes!

I’m in the states from next Thursday until late December so going to tackle it when I get back.
I was going to go the vinegar route but this gubbins sounds just the job. Is there a specific recipe for a 550 tank, eg. Can I do it with one tub? Just so I order enough to be here waiting for when I get back?

If the tank is pitted, I'd be tempted to seal with tank sealant.
Send us a postcard!

I’d love to use evaporust but it’s a bit cost prohibitive tbh. This gubbins described earlier has a good right up and I can do the tank from top to bottom for 16 quid so it’s looking favourable. It would cost about £50 to do the same with the evaporust. I do use it but only on bits n bobs. How’s the hand doing, you managing a

I used deox-c in my tank for 24 hours and it came up really clean. 👍What size did you need to use?

Exactly. If I remember right it can make up a 20 litre solution. I didn't have a big enough container to do it in one go, so dissolved half the tub in a large clean bucket, poured it in the tank, then did the second half. Fill the tank to the brim, close the cap and leave it. Just agitate/rock the tank every now and again.
It's worth getting a large container to keep the solution in when you're finished, it can be used again several times.
