Apologies if this is a stupid question. Someone told me this years ago but I never gave it much thought at the time. I compared two brands of oil. One brand has little to no odour while the other has a strong petroleum type smell. They are both semi-synthetic oils priced at the lower end of the market.
I haven't mentioned the brand names as I know this may well be nonsense and I wouldn't want to imply anything negative about a product without justification.
Cheers
