Works great. Never had the outside covered with oil. If you do you have a leak somewhere it’s not the hose.

Very happy with the quality. I ordered 2 and received 28 Im giving four stars because the delivery took a bit longer than expected.

Does what it is supposed to do, but the outside surface becomes moist with oil soon after initial use. No dripping, but I wish it would stay dry.

Yes it can.

Q: Can this hose be used for a oil pressure line from the engine to the oil pressure gauge?

306 hose is approved for instrument air and vac lines, you would need to speak with your A&P/IA to determine the correct hose for your application.
