Which is better for changing oil in a car?

Both move 1-4 L/min through 6 mm and 8 mm inlets, so either drains a sump at about the same speed. The LAYAN includes a 1000 mm 10 mm outlet hose, which helps route waste oil into a container.

Is the NORJIN worth $2 more?

Only if the aluminum-alloy housing and pure copper motor matter to you. Flow, current draw and the 30-minute work cycle are the same, so the LAYAN is the better value on paper.

Neither maker publishes a service life. Both are rated for a 30-minute work cycle, so letting the pump cool between runs is the main thing that protects either one.

Can either pump diesel or transfer fluid, not just oil?

The LAYAN is listed for diesel and fluid transfer as well as oil. The NORJIN is sold as an engine oil pump, so check its listing before using it on fuel.

Do both fit the same hoses?

Yes. Both take 6 mm and 8 mm inlet hoses and a 10 mm outlet. The LAYAN ships with all three tubes; the NORJIN's hose lengths are not stated.

Which is easier to store and carry?

The NORJIN is smaller at 16 x 6.5 cm. The LAYAN weighs 1500 g, so it is the bulkier of the two in a toolbox.
