Actually -- not. That's why most of us have such fancy gas pumping nozzles these days - trying to keep the fumes down. But, yeah, if you had to, outside would be better than inside.
Lubes are a different topic, I suppose, but I think enough of my lube technique to share it - simple wax. Americans call it paraffin, or canning wax. I think Brits call it paraffin wax. Another petrochemical product, but one known and in use since Roman times, at least.
Back when I was racing, I was also riding 7-10K miles per year. I had tried a lot of lubricants, and ended up quite satisfied with a silicone lube I found. I had gotten my chain life up to about 2K miles per chain! Then a friend told me he used the wax method, and got 3K plus. I said, "but wax is not a lubricant!" Which is technically correct - but I tried wax, and I've never gone back. Using wax increased my chain life by at least 50%. The only thing I know of that is better would be to use an oil bath - but nobody wants to carry that heavy casing you used to find on bikes that had an oil bath!
I suppose, actually, that there might be superior versions of wax available today, and perhaps superior lubes. Idk - as I don't ride enough any more to justify messing about with it like I did back then.
