Does this require oil?

Thank you for asking. Yes, you need to apply the oil to the trimmer before and after each use for lubrication. Part number for it is WER203X7910. You can find it here: panasonic.encompass.com/item/10387510/Panasonic/WER203X7910/

When i go to the barbor, i ask for a 3.5. does that mean 3.5mm? or is 3.5 different with this trimmer compared to a barber 3.5?

Yeah heart like an ostrich has more of the brain of an ostrich. He some how says that 1 inch is 25.4mm But, then contends that 3 inches is somehow equal to 10mm. Besides that. This product is a scam. You can buy a much cheaper version by the same company that has the same total length of dial settings, 1mm to 10mm, in a 19 setting dial. This one technically has more options, but more settings isn't always better. Seriously who's looking at anyone's beard that closely. The addition of the blade guards is just a real kick in the teeth. If you like to keep your beard longer like I do. You can buy a very nice trimmer that will come with blade guards of various sizes that'll do just as good of a job as this overpriced piece of junk for 1/3 of this price. My advice is don't waste your money here, this is an over engineered, way to expensive product that won't do you any better than it's counterparts. Don't waste your money on things that, claim to have more features, when their proformance is going to be the same. I also just have to point out that, Heart like an ostrich also gave specs about Wahl products when this product is clearly Panasonic, further confirming their lunacy.

As this is a washable unit, does it need a protective oil or some other maintenance to prevent rusting?

Why does this need blade oil and other brands do not?
